HSRS-P
Quick Overview
PILOTED SPIKE RELIEF VALVE
Mounting Surface: 800 Oilgear Standard Cavity
Max Pressure: 5000 PSI (345 bar)Rated Flow Rate: 35 gpm (133 l/min)
The HSRS piloted relief valve is a fast acting valve designed to prevent high pressure spikes that can occur with slower acting valves, and regulate system maximum pressure consistently.
The inlet pressure is ported thru an orifice (lower main spool) to the pilot relief valve (in the upper portion of the body). When the inlet pressure exceeds the pilot valve setting, pressure on the top side of the main spool is relieved, A pressure imbalance then exists across the main spool, and port 1 pressure raises the main spool to allow flow to port 2.
The HSRS cartridge valve is constructed of steel parts, and operating parts are hardened and ground as required. The cartridge is designed for easy service and field repair.
