Quick Overview
RELIEF VALVE FOR PILOT OPERATION
Mounting Surface: Oilgear Standard 1200, 1600, 2000
Max Pressure: 5000 PSI (345 bar)Rated Flow Rate: 62 to 220 gpm (235 to 834 l/min)
The HSR cartridge is a fast acting relief valve when controlled by a HSLR pilot operator. The cartridge is designed for continuous duty applications to regulate system maximum pressure continuously and smoothly.
A HSLR pilot relief valve must be connected via port 3 to top (spring side) of the main spool. Then the inlet pressure (ported thru the valve) exceeds the pilot setting, pressure on the top side of the spool is relieved. A pressure imbalance then exists across the main spool, and port 1 pressure raises the spool to allow flow to port 2.
Multiple pressure ranges, proportional pressure, and vent operation options are available thru the use of standard pilot control modules.
The HSR cartridge valve is constructed of steel parts, and operating parts are hardened and ground as required. Cartridges are designed for easy service or field repair.
