— Pressure safety relief valves are typically used to control pressure on boilers in heating systems, on stored hot water cylinders in domestic hot water systems, and generally in water systems. T&P relief Valve Function:

This is caused by water expanding during the heating cycle. The T/P valve will then relieve pressure by releasing hot water drips to the drain line. It is recommended that an expansion control valve be fitted to the cold water supply line to reduce cold water(not hot water) during the heating cycle expansion, thereby saving energy and increasing the life of the T&P relief valve. Local regulations may require installing an expansion control valve in the cold water supply line.

With so many brass pressure relief valves to choose from, it can be challenging to find the right one. Whether you are looking for a valve that has a higher flow rate or is more durable, here are some essential things to consider when choosing your next brass pressure relief valve:

Once you have answered these questions, you can narrow your search for the perfect brass pressure relief valve. For example, if you have a system that operates at a high PSI, you will need a valve to withstand higher pressures. Conversely, if you have a minor piping system, you may consider a valve with a lower flow rate.

Always read the manufacturer’s instructions carefully before installing, no matter what type of valve you choose. By following these simple guidelines, you can be confident that your new brass pressure relief valve will provide years of reliable service.

Answering these questions will make it easier to narrow your search for the perfect brass pressure relief valve. For example: if you have a more extensive piping system with high operating pressures, you may want to consider one that can handle higher flow rates and has extra features (such as a pilot light). Conversely, if you choose between two valves that can withstand up to 150 PSI but only differ by 0.25 GPM in their flow rate, then maybe select based on price alone. The key here is knowing what factors matter most when purchasing something like this, so don’t be afraid to ask for help from a qualified technician.

Like anything else, it’s essential to read the manufacturer’s instructions carefully before installation. Following these guidelines ensures that your new brass pressure relief valve will provide years of quality service!

Once you have chosen the perfect brass pressure relief valve for your system, it is essential to install it properly. These instructions are based on a typical installation with similar-sized piping and valves. The first step in choosing an appropriate location for installing your new valve will be finding out what type of piping system you currently have.

Once you have determined the pipe size in PSI, it is time to find what pressure relief valve will work with your system. Now that you know the piping system and pipe size, finding a brass pressure relief valve should be as easy as pie!

Valves for industrial applicationsIn order to prevent the uncontrolled rise in pressure in pressure vessels or pressurized pipelines, a safety valve is inserted. The safety valve is designed so that it opens at a given maximum pressure, thereby relieving the line or the container. Safety valves find their use in almost all areas of the pressure vessel and pipeline construction. In cryogenics as a spring-loaded safety valve for example.

The primary purpose of a safety valve is to protect life, property and the environment. Safety valves are designed to open and release excess pressure from vessels or equipment and then close again.

The function of safety valves differs depending on the load or main type of the valve. The main types of safety valves are spring-loaded, weight-loaded and controlled safety valves.

Regardless of the type or load, safety valves are set to a specific set pressure at which the medium is discharged in a controlled manner, thus preventing overpressure of the equipment. In dependence of several parameters such as the contained medium, the set pressure is individual for each safety application.

Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).

Reliably safe processes - this is what our KIESELMANN safety valves with EAC certification and CE type approval for gases stand for. They protect automatically, without additional auxiliary power, as soon as the system pressure has exceeded the adjusted system pressure and close reliably and quickly when the safe operating pressure is reached again.

With safety valves from our company you ensure trouble-free operation and avoid damage due to overpressure. The ideal protection for all connected system parts, containers, pipelines and your employees.

KIESELMANN safety valves open automatically as soon as the pressure has exceeded a previously defined value. The closing is then effected by the force of a spring or weight. They are used in systems where liquids and gases are present. The response pressure is set at the factory precisely according to your requirements and is sealed to protect against unwanted changes. We will be happy to help you with the design of the appropriate safety valve.

Against overpressure, for the highest hygiene requirements. KIESELMANN safety valves feature a compact and closed housing construction. All moving parts are inside the housing, so no functional parts can be blocked from the outside. This also allows adequate cleaning of the exterior surfaces. The spherical inner contour with the hygienically designed clamping connections provides excellent CIP (cleaning-in-place) and SIP (sterilisation-in-place) properties. And we also thought: the valve insert can be removed from the housing for maintenance purposes without changing the pressure setting.

We like to be measured by our success: Our safety valves have been used successfully for many years in numerous processes in the food and pharmaceutical industries.

A little product education can make you look super smart to customers, which usually means more orders for everything you sell. Here’s a few things to keep in mind about safety valves, so your customers will think you’re a genius.

A safety valve is required on anything that has pressure on it. It can be a boiler (high- or low-pressure), a compressor, heat exchanger, economizer, any pressure vessel, deaerator tank, sterilizer, after a reducing valve, etc.

There are four main types of safety valves: conventional, bellows, pilot-operated, and temperature and pressure. For this column, we will deal with conventional valves.

A safety valve is a simple but delicate device. It’s just two pieces of metal squeezed together by a spring. It is passive because it just sits there waiting for system pressure to rise. If everything else in the system works correctly, then the safety valve will never go off.

A safety valve is NOT 100% tight up to the set pressure. This is VERY important. A safety valve functions a little like a tea kettle. As the temperature rises in the kettle, it starts to hiss and spit when the water is almost at a boil. A safety valve functions the same way but with pressure not temperature. The set pressure must be at least 10% above the operating pressure or 5 psig, whichever is greater. So, if a system is operating at 25 psig, then the minimum set pressure of the safety valve would be 30 psig.

Most valve manufacturers prefer a 10 psig differential just so the customer has fewer problems. If a valve is positioned after a reducing valve, find out the max pressure that the equipment downstream can handle. If it can handle 40 psig, then set the valve at 40. If the customer is operating at 100 psig, then 110 would be the minimum. If the max pressure in this case is 150, then set it at 150. The equipment is still protected and they won’t have as many problems with the safety valve.

Here’s another reason the safety valve is set higher than the operating pressure: When it relieves, it needs room to shut off. This is called BLOWDOWN. In a steam and air valve there is at least one if not two adjusting rings to help control blowdown. They are adjusted to shut the valve off when the pressure subsides to 6% below the set pressure. There are variations to 6% but for our purposes it is good enough. So, if you operate a boiler at 100 psig and you set the safety valve at 105, it will probably leak. But if it didn’t, the blowdown would be set at 99, and the valve would never shut off because the operating pressure would be greater than the blowdown.

All safety valves that are on steam or air are required by code to have a test lever. It can be a plain open lever or a completely enclosed packed lever.

Safety valves are sized by flow rate not by pipe size. If a customer wants a 12″ safety valve, ask them the flow rate and the pressure setting. It will probably turn out that they need an 8×10 instead of a 12×16. Safety valves are not like gate valves. If you have a 12″ line, you put in a 12″ gate valve. If safety valves are sized too large, they will not function correctly. They will chatter and beat themselves to death.

Safety valves need to be selected for the worst possible scenario. If you are sizing a pressure reducing station that has 150 psig steam being reduced to 10 psig, you need a safety valve that is rated for 150 psig even though it is set at 15. You can’t put a 15 psig low-pressure boiler valve after the reducing valve because the body of the valve must to be able to handle the 150 psig of steam in case the reducing valve fails.

The seating surface in a safety valve is surprisingly small. In a 3×4 valve, the seating surface is 1/8″ wide and 5″ around. All it takes is one pop with a piece of debris going through and it can leak. Here’s an example: Folgers had a plant in downtown Kansas City that had a 6×8 DISCONTINUED Consolidated 1411Q set at 15 psig. The valve was probably 70 years old. We repaired it, but it leaked when plant maintenance put it back on. It was after a reducing valve, and I asked him if he played with the reducing valve and brought the pressure up to pop the safety valve. He said no, but I didn’t believe him. I told him the valve didn’t leak when it left our shop and to send it back.

If there is a problem with a safety valve, 99% of the time it is not the safety valve or the company that set it. There may be other reasons that the pressure is rising in the system before the safety valve. Some ethanol plants have a problem on starting up their boilers. The valves are set at 150 and they operate at 120 but at startup the pressure gets away from them and there is a spike, which creates enough pressure to cause a leak until things get under control.

If your customer is complaining that the valve is leaking, ask questions before a replacement is sent out. What is the operating pressure below the safety valve? If it is too close to the set pressure then they have to lower their operating pressure or raise the set pressure on the safety valve.

Is the valve installed in a vertical position? If it is on a 45-degree angle, horizontal, or upside down then it needs to be corrected. I have heard of two valves that were upside down in my 47 years. One was on a steam tractor and the other one was on a high-pressure compressor station in the New Mexico desert. He bought a 1/4″ valve set at 5,000 psig. On the outlet side, he left the end cap in the outlet and put a pin hole in it so he could hear if it was leaking or not. He hit the switch and when it got up to 3,500 psig the end cap came flying out like a missile past his nose. I told him to turn that sucker in the right direction and he shouldn’t have any problems. I never heard from him so I guess it worked.

If the set pressure is correct, and the valve is vertical, ask if the outlet piping is supported by something other than the safety valve. If they don’t have pipe hangers or a wall or something to keep the stress off the safety valve, it will leak.

There was a plant in Springfield, Mo. that couldn’t start up because a 2″ valve was leaking on a tank. It was set at 750 psig, and the factory replaced it 5 times. We are not going to replace any valves until certain questions are answered. I was called to solve the problem. The operating pressure was 450 so that wasn’t the problem. It was in a vertical position so we moved on to the piping. You could tell the guy was on his cell phone when I asked if there was any piping on the outlet. He said while looking at the installation that he had a 2″ line coming out into a 2×3 connection going up a story into a 3×4 connection and going up another story. I asked him if there was any support for this mess, and he hung up the phone. He didn’t say thank you, goodbye, or send me a Christmas present.
