Safety Valve Maintenance and Testing
Under normal operating conditions a "try lever test" should be performed every two months. Under severe service
conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be performed more often.
A "try lever test" should also be performed at the end of any non-service period.
Hot, high pressure fluid may be discharged from body drain and vent during "try lever" test. Care must be taken
to avoid any bodily contact.
High sound levels may be experienced during "try lever" test. Wear proper safety equipment and exercise extreme
care! Test at, or near, half of the operating pressure by holding the test lever fully open for at least two seconds to
flush the valve seat free of sediment and debris. Then release lever and permit the valve to snap shut.
If lift lever does not activate, or there is no evidence of discharge, turn off equipment immediately and contact a
licensed contractor or qualified service personnel.
