Merrill PRVHDNL150 1-1/2″ No-Lead Heavy Duty Pressure Relief Valve

Description

Features:

• 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.
• All PRV valves are field adjustable – by removing the cap and turning the internal disk down to increase pressure.
• All PRV, SSPRV, and PRVNL valves must be set at 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.
