High pressure lift disk check valve
Description
Adopt straight way body, there are three kind of body, die forging, free forging and casting.
Pressurized seal design, more reliable the seal.
Lift disk,medium enter from lower position and go out from higher position, it is benefit to prevent counter flow.
Disk guide part is equipped with pressure relief hole, opening and closing buffer action
The sealing surface is welded with hard alloy. Wear resistant and corrosion resistant, reliable sealing, long service life.
The valve is vertically equipped on the pipe.
