pressure safety valve
Safety valves protect installations against overpressure: when the set pressure is exceeded, they open automatically and release the excess pressure, then close again as soon as the pressure drops.
Available in brass, stainless steel, bronze and cast iron, with threaded or flanged connections — for water, air, steam and gases.

Safety valves for reliable overpressure protection
A safety valve is the last line of protection against excessive pressure in an installation. A spring-loaded mechanism keeps the valve closed until the set opening pressure is reached; above that, the valve opens automatically and releases the excess pressure in a controlled way. As soon as the pressure drops back below the set value, the valve closes again on its own. The valve operates fully self-acting, without external energy, protecting pressure vessels, boilers and pipework against damage. Available in brass, stainless steel, bronze and cast iron, with threaded or flanged connections.
