MAIN CHARACTERISTICS of
Safety relief valve SD 737

SD 737 relief valves are spring self-actuated valves. When the force exerted by the fluid pressure is greater than the force exerted by the spring, the valves open automatically allowing the fluid to exit the valves. The relief valves are safety devices which prevent the maximum allowable working pressure in the system from being exceeded. Direct acting relief valves are suitable for air, natural gas, LPG and CO2.
