High pressure swing check valve
Description
Adopt straight flow body, there are three kind of body, die forging, free forging and casting.
Pressurized seal design, more reliable the seal.
Swing disk,freedom open and close,prevent counter flow.
The connection between the disk and the arm is kinetic, good concentric, reliable sealing.
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.
