Description

PRVHDNL's are recommended for use up to 150 PSI on water systems only. 

Recommended for all cold water system installations - to protect against damage to piping and pressure tanks. PRVHDNL's are set at 75 PSI. PRV's have a plus/minus 15% setting accuracy

Note: Merrill pressure relief valves may not reseat themselves after pressure relief. Manual disassembly and reseating of the valve may be required. Repeated opening of a pressure relief valve is beyond intended use and voids warranty 

*Note: ALL PRV valves are field adjustable - by removing the cap and turning internal disk down to increase pressure. Field adjustment of valve voids warranty. 

**Note: Valve warranty voids after a change in adjustment due to possible error

Warning: ALL PRV, SSPRV, and PRVNL valves must be set a minimum of 15 PSI above the typical high of the water system pressure, so valve chatter or rapid open and close will not occur. Valve chatter can cause the failure of the valve and voids warranty.
