TYPE 'C' flanged RESET RELIEF VALVE utilizes the same mechanical principle as the Type B Reset Valve. The primary difference is the sub and flanged body. The valve is designed for Hydraulic or Gas use at the following pressure ratings: Hydraulic use: 1500-6200 PSI W.P. 
Reset relief valve processing by advanced heat treatment is made from high-strength alloy steel and intensive stainless steel, which is against corrosion, impact, and abrasion.
It consists of a piston, crank, linkage, and loaded spring-balanced device. The piston is designed by an internal and external piston device and Oil pressure-balanced device. It realizes auto and hand pressure release.
It is very convenient and safe for us to maintain.
* Corrosion resistance, impact resistance, wear resistance.
* Balancing device adopting piston, crank, connecting rod mechanism, and imported load spring.
* Automatic pressure relief and manual pressure relief, manual reset.
