Maintenance and Testing Instructions

CAUTION! Before testing, make certain discharge pipe is properly connected to valve outlet and arranged to

contain and safely dispose of discharge (see Installation Instructions).

Under normal operating conditions a “try lever test” should be performed biannually in steam service, with a visual

inspection every 2 months and an annual pressure test. In air/gas service, perform a visual inspection every 6 months, a

lever test annually and a pressure test every 3 years. Under severe service conditions or if corrosion, pitting, and/or

deposits are noticed within the valve body, testing must be performed more often. A “try lever test” should be performed at

the end of any non-service period.

CAUTION! High sound levels may be experienced during lever test. Wear proper safety equipment and

exercise extreme care.

Test at or near maximum operating pressure by holding the test lever fully open for at least five seconds to flush the valve

seat free of sediment and debris. Then release lever and permit valve to snap shut. If lift lever does not actuate, or there is

no evidence of discharge, turn off equipment immediately and contact a licensed contractor or qualified service personnel.

For resetting, adjustment or repairs contact Conbraco Industries for the appropriate service facility.

Neither Conbraco Industries, Inc. nor it’s agents assume any liability for valves improperly installed or maintained.
