The valve’s relief of elevated liquid, gas, or steam pressures prevents damage to the system or vessel. The safety valves open when a preset pressure is exceeded and automatically shut when pressure ...

In steam boiler applications, pressure relief valves (PRVs) are the silent sentinels — the last line of defense against potentially disastrous overpressure situations. In a perfect world, boiler ...

For the past 15 years, pilot-operated safety relief valves (POSRVs) have effectively and reliably protected economizers on Section I power boilers in overpressure situations, working in tandem with ...

Q: My water heater leaks from some type of a brass valve on the side of the tank near the top. There is a pipe that comes out of the valve at a right angle that looks like it goes through the wall.

H5600A pressure relief valves in 1/2- by 3/4-in. sizes, are now available with 400-psig pressure settings. Matching rupture disc assemblies, also with 400-psig pressure settings, are available to ...

A 0.281-in.-diameter pressure-relief valve now comes in a NACE-compliant model for harsh-duty applications in the oil-tool industry A 0.281-in.-diameter pressure-relief valve now comes in a ...

In this image, natural gas is discharged through a two-inch diameter pipe and ignited as part of an SwRI-conducted test to evaluate pressure relief valves. Temperatures and heat fluxes were measured ...

These new reduced-capacity pressure relief valves — H5600R (1/2 by 3/4 in.) and H5602R (3/4 by 1 in.) — are designed to safely and dependably deliver over-pressure relief to a range of vessels in ...
