blow off pressure safety valve in stock

Yep it works as intended so how could I give it anything but 5 stars.I purchased this overpressure safety valve to upgrade my 150 psi system to a 200 psi system because my pump and tank can easily handle it.Allong with a 200 psi pressure shut off switch and hornblasters pressure regulator for the ***** horns. I get much more volume in my 5 gallon tank for my onboard air system making airing up the tires after 4x4ing much quicker.

1/4" MNPT ASME safety valves are manufactured to ASME standards and certified by the national board of boiler and pressure vessel inspectors. Valves are interchangeable with all other ASME valves of same size and pressure. Valve resets after pressure drops by 50%.

Made from 6061 Billet Aluminum stock, it is a two piece adjustable valve that relieves pressure in the crankcase due to blown head gaskets or piston failure which can result in lots of air volume bypassed to the engines crankcase. It also protects in the situation where the vacuum pump isn"t working due to a thrown belt. The GZ Blow Off Valve PN VCB100B consists of a base with a nylon washer and nut that can be installed in a standard grommet hole in a valve cover or placed in a valley pan and a top that may be removed to replace the spring of Teflon ball inside. The top has an o-ring between it and the base to which is attached for leak free sealing. Once the valve is activated, the blow-by gases are vented through a fitting in the top which may be routed to a catch can or other means of containing fluids in the gases.

A pressure relief valve (blow off valve) is essential for any turbo, blower or nitrous equipped high performance engine with a Vacuum Pump. If for some reason the pump can"t keep up with crankcase pressure (like a hole in the piston on a blower car), the blow off valve will safely vent that pressure to a puke tank instead of pushing out a gasket in the engine and getting oil under the tires.

Safety Relief Valves guard against over pressure conditions in compressors and other pressure vessels. These units are manufactured out of brass bar stock to ensure a non-porous, strong fitting. Seats are silicon rubber to provide a long leak free service life. These valves are ASME approved.

Often referred to as a pop-off valve, a T&P valve helps manage temperature and pressure in the water heater. It functions by automatically popping open (hence pop-off) and draining hot water from the tank to reduce temperature and pressure. This is why people call it a water heater pressure relief valve (or pressure reducing). Technically, this is incorrect. A PRV is what you install on the mainline supply to the house. T&P valves are for the water heater.

Hopefully, it"s open because it"s doing its job. It"s supposed to open to relieve pressure in the tank when necessary. If this is happening with frequency, you should consider lowering the temperature. If that doesn"t seem to make a difference, you may have a compromised T&P valve. There are two things you want to look for:Is it leaking rather than "popping" open to drain? Hard water can cause the internal components to seize up, creating a leak. It can be hard to detect this sort of leak if you are draining the T&P valve right into a pipe, so if you have that setup, try to be extra observant.

The pressure in the tank can wear the valve down, and what you"ll see is the T&P starts popping open at lower and lower temperatures. You may not have hard water in your area, but every water heater tank introduces pressure into the equation. This issue is an eventuality.

Chances are you might"ve been tempted to hit the trip lever you see on the valve. You"re on the right track, except you want to be clear of the valve once the hot water starts gushing out. Give the trip lever a quick flip and get out of the way.
