DIRECT ACTING EXTERNAL OPERATED NORMALLY OPEN SEQUENCE VALVE
Mounting Surface: 1200 Oilgear Standard CavityMax Pressure: 5000 PSI (345 bar)
Rated Flow Rate: 39 gpm (148 l/min)
The HSUO-DA sequence valve disconnects primary and secondary system branches after the pressure requirement in a third branch has been satisfied.
As the pressure at port 1 overcomes the spring resistance, it moves the main spool to block port 3. Because the spring chamber is connected (separately) to drain, back pressure at operating ports will not alter resistance.
Direct acting for fast, accurate responses. Several pressure ranges are available. The cartridge is constructed of steel parts, and operating parts are hardened and ground as required. The cartridge is designed for easy service and field repair.
