Complies with MSS-SP-80-97 300 WSP 600 WOG Non-Shock Service 100% Pressure Tested Threaded Ends Rising Stem Swivel Disc Holder Seat & Disc 400-500 Brinnell Stainless Steel Max Pressure 390 PSI @ 500 F Max Pressure for Boiler Blow-Off 312 PSI Care must be taken in blow off piping so that no water hammer effect causes shockto the “Y” blow off valve, especially in cases where a boiler has two blow-off lines.In such cases both lines should be piped to a common set of blow off valves or eachblow off line should be piped separately to the blow down separator. Excessive waterhammer or shock can destroy valves and piping and could cause injury.
