Forged Steel Pressure Seal BW Globe Valve

Forged Steel Y-Type Thread Globe Valve

High - pressure globe valve adopts self - sealing structure in the middle chamber, sealing performance is good.The two ends of the branch pipe are welded structure.The sealing surface of valve disc and valve seat is made of stellite cobalt-base hard alloy surfacing welding, with good abrasion resistance, high temperature resistance and abrasion resistance.The stem is tempered and surface nitrogenated.Bonnet stuffing box depth reasonable packing and corrosion inhibitor seal reliable.The valve has an inverted seal structure to ensure that the valve does not leak through the stem when open for operation.Widely used in petroleum, chemical, natural gas, metallurgy, chemical fiber, paper, urban construction, and other fields.
