Of all the challenges you face keeping your customers’ plants operating at full capacity, safety and relief valves shouldn’t be one of them. NASVI’s job is to give you the confidence that your valve supply chain is rock solid regardless the pressure it’s under.

Expect expert service, the most extensive inventory in the nation and emergency service whenever needed. That’s how we’ve got our customers’ backs since 1975.

A customer urgently needed information on the availability of five 4-inch liquid flanged valves. Unfortunately, the end user had ordered the wrong valves and desperately needed the correct ones right away. NASVI not only had them in stock, but also shipped the valves same day. It was a happy ending to the customer’s frustrating day of tracking down the valves only to hear there was a six-week lead time. It’s why our customers’ call NASVI, their trusted safety valve distributor, first.

When the pressure is on, you can count on us to come through with 35,000 safety valves in stock shipped same or next-day. When there are unknowns involved, our experienced applications engineers guide you to the right valve make and model so you can be your customers’ hero.

Choosing remanufactured safety and relief valves is a smart alternative for saving money and minimizing down time. It makes good sense for the majority of industrial uses because they are:

How much time and money have you lost because of price, availability and delivery times associated with new safety valves? Get production back up to speed affordably and confidently with remanufactured valves.

If a remanufactured valve doesn’t meet your expectations for any reason, within 5 days of receipt and prior to installation, return it for full credit plus shipping and return freight costs.

Kunkle Relief Valve OverviewWhen it comes to industrial and commercial safety and relief valve products, Kunkle’s valve’s catalog is second to none in steam, air, gas, and liquid applications.

Kunkle relief valves range in size from ¼” NPT to 6” flange and are suitable in cryogenic and high temperatures up to 800°F environments at vacuum to 7,500 psig pressure. Kunkle Valve’s code certifications meet several global and national board standards, including ASME Section I, Section IV, and Section VIII, PED, CRN, TU and Chinese, as well as non-code requirements.

Relief Valves for Steam ServiceSteam supplies heat for industrial and chemical processes and also is used to heat buildings, supply mechanical energy, and drive mechanical equipment. Steam moves from the boiler to the end point, then heats by direct heating or indirect heating through a heat exchanger. Kunkle steam relief valves are critical to protecting equipment such as boilers, steam lines, and pressure valves, from being over-pressurized.

Relief Valves for Air ServiceKunkle designs valves for air service, for example for air compressors in mechanical shops and small factories where either low-pressure or high-pressure air is required. NASVI stocks Kunkle relief valves for air service in iron, steel and bronze for a variety of uses.

Relief Valves for Liquid ServiceKunkle also makes valves for liquid service, which provide bypass relief in a variety of applications and liquid types.

More About KunkleKunkle Valve is a renowned pressure relief valve manufacturer. Erastus B. Kunkle invented the safety valve to prevent overpressure in locomotive engines. Kunkle patented it in 1875. Since that time, Kunkle has earned its reputation for high-quality valves, and other equipment manufacturers ship their products with Kunkle’s valves pre-installed.

NASVI has stocked Kunkle safety relief valves since we opened in 1975, so we are confident when we call ourselves Kunkle safety valve experts. Every day we fulfill orders for our customers looking for Kunkle relief valves for steam, air, gas, and liquid applications.

Our two-truck unit responds to customer requests anywhere, offering on-site repair and resetting of safety valves during scheduled maintenance shutdowns.

Step into the mobile repair unit and you’ll find all the equipment necessary to perform highest-caliber repairs: sand blaster, compressor, lathe, mill/drill press, lapping machine–-it’s all inside. There’s also a Consolidated® seat-resurfacing machine with all adapters for every orifice in the Maxi-Flow® boiler line. Completed valve work will carry the VR stamp.

The Field Service Unit also includes a state of-the-art computerized lift-assist testing unit that allows for testing set pressures and resetting high-pressure safety valves in the field. The testing unit makes testing valves that are welded in-line or stationary possible without removing the valves. Your customers won’t be required to pressure down or increase pressure to test for set pressure. The lift assist testing unit also allows for resetting valves after repairs have been made while the valves are on-line.

If you have prospects or customers that bought their replacement valves elsewhere because you haven’t been able to provide on-site service, you will want to get back with them and talk about this service. If you have questions about pricing and scheduling of our Field Service Unit, give us a call at (800) 800-8882.

Pressure relief valves are designed to protect equipment from overpressure. The valve should be handled with care, not subject to heavy shock loads, and protected to prevent dirt from getting inside. Failure to do so could result in property damage or serious injury to personnel.

Mount the valve in a vertical position so that the valve body is self-draining. If a body drain port is provided, make sure it is open when required by the ASME code. Do not plug any bonnet vent openings. The inlet piping should be as short as possible, with no elbows, and equal to or greater than the size of the pressure relief valve inlet connection. This will help limit the inlet pressure drop to 3% or less when the valve is relieving.

When discharge piping is connected to valve outlet, make sure it is self-draining when a body drain port is not used. The valve should not be connected to any discharge pipe that contains pressure before the valve opens or to any pipe where the pressure build-up is greater than 10% of the set pressure when the valve is open and relieving. Discharge piping other than a short tailpipe must be supported by something other than the valve. For steam service, a drip pan elbow or flexible connection between the valve and the pipe should be used to prevent excessive pipe stress, due to thermal expansion, from being imposed on the valve body.

For threaded valves, apply a small amount of pipe thread sealing compound to external threads only. Do not put any sealing compound on the first thread or any internal threads. To do so may cause the sealing compound to enter the valve and cause seat leakage. Use wrench flats provided to tighten the valve to the connecting pipe. Do not use the valve body or bonnet and do not over-tighten. To do so may cause valve leakage.

Maintain a system operating pressure at least 5 psig or 10% below the set pressure of the valve – whichever is greater. Operating too close to the valve set pressure will cause seat leakage and will shorten the time between valve maintenance.

Do not use the safety valve as a control valve to regulate system operating pressure. Excessive operation will cause the seat to leak and will require more frequent valve maintenance.

ASME Code-stamped valves equipped with lift levers are designed to be operated only when the system pressure is 75% of the set pressure or greater. When hand operating the valve, hold it open long enough to purge any foreign matter from the seat area. If a cable or wire is attached to the lift lever for remote actuation, make sure the direction of pull is the same as it would be if the lever were pulled directly by hand.

Maintenance should be performed on a regular basis. We recommend an initial inspection interval of 12 months. Depending on the service conditions and the condition of the valve, the suggested inspection interval may decrease or increase.
