7 1/16" HYDRAULIC HCR VALVE WITH GUIDE ROD

Nominal Bore:2-1/16"-7-1/16"
Working Pressure:2000-15000psi

Material :Alloy Steel

Standard:API 6A 

The hydraulic gate valve are widely used in the automatic control systems and remote control systems, featuring the hydraulically controlled opening and closing, stable performance and easy operation.

The valve use the self seal packing structure,needs no constant adjustment and the feature of this valve is very light open & close and a reliable seal.

An assisting sealing grease injection structure is set in the packing to have the sealing performance absolutely reliable and get a true null leak,settling the problem for the packing place of universal valves to be easiest leak outward.

The valve with the elastic seat and fixed spherical surface seal structure, thus form a better tightness for the seal part by the medium pressure and the valve can achieve the bid-directional tightness with zero leakage.
