1 4 npt safety valve price

Brand new field adjustable, Non Code 1/4" NPT pressure relief valve kit. This is a high quality relief valve that can easily be adjusted to any pressure between 25 and 200 PSI. This valve kit comes with 4 springs. These springs are easy to change out and give you the ability to easily alternate relief pressure anywhere from 25-50, 50-100, 100-150, and 150-200 PSI! The knurled thumbscrew and jam nut make adjustments easy and repeatable. This valve can be used in a variety of applications and has a max temperature rating of 250°F. This relief valve is made of solid brass and has an inner silicon rubber seal and a zinc plated music wire spring.

A Pressure Relief Valve (also known as a Safety Valve, Overpressure Relief Valve, or simply a Relief Valve) limits the amount of pressure in a compressed gas system. Without such a valve in place, pressure could build up beyond what the system is designed for and cause equipment failure. The Pressure Relief Valve opens at a designed “set pressure” to protect the system against failure from being overpressurized.

Atmospheric Pressure Relief Valve, Superior HVACR Products, 1/4 NPT, 425 PSI, Body Construction: Brass, Seat Material: 100 % PTFE, Spring Material: stainless steel, Minimum Temperature: -40 degrees F, Maximum Temperature: 325 degrees F, Discharge Capacity: 14.3

This is a diaphragm and spring type relief valve where the spring constantly opposes the pressure acting against the diaphragm which seals off the inlet port from the outlet port at the valve seat. The desired relief or bypass pressure is achieved by compressing the spring until the spring force is adequate to balance the pressure force acting against the diaphragm. When the inlet pressure exceeds the set pressure, the diaphragm will open to relieve and bypass the excess pressure.The valve will operate in a vertical orientation as illustrated, horizontal, or any other orientation.

Although the ports are inline, this is not a "through flow" model where flow continuously passes through the valve. If this valve were to be installed in a flow line, it would shut off flow to the line completely and open only when the set pressure is exceeded. This valve is typically mounted to a device to be protected such as a tank or other pressure containing device. If a flow stream needs to be protected from overpressure, then the valve is mounted on the side of a Tee, or at the end of a line branch where it will pass excess flow only when the valve opens. The outlet port of the valve is usually piped to a drain or discharged directly to atmosphere only if the liquid or gas is safe to be discharged without injuring personnel or damaging equipment nearby . For a true "through flow" model, see our model RVT05 which is a piston type that has three ports.
