Product Detail
HSU
Quick Overview
NORMALLY CLOSED SEQUENCE VALVE FOR PILOT OPERATION
Mounting Surface: 1200, 1600, 2000 Oilgear Standard Cavities
Max Pressure: 5000 PSI (345 bar)Rated Flow Rate: 39 to 170 gpm (148 to 644 l/min)
When operated by a HSLR pilot operator, the HSU sequence valve connects primary and secondary branches after the pressure requirement on a third branch has been satisfied. This valve can be circuited to be operated by multiple pressure settings.
A HSLR pilot relief valve must be connected via port 4 to top (spring side) of the main spool, and pressure must be connected to port 1 to operate the relief valve which pilots the sequence valve to connect ports 2 and 3. When the inlet pressure (ported thru the valve) exceeds the pilot setting, pressure on the top side of the sloop is relieved. A pressure imbalance then exists across the main spool. Port 1 pressure raises the spool and allows from between ports 2 and 3.
A trim adjustment is provided to vary the cracking and re-seating pressure. The cartridge is constructed of steel parts, and operating parts are hardened and ground as required. The cartridge is designed for easy service or field repair.
