Non-lubricated plug valve utilizes a tapered or cone-shape that acts as a plug and presses a polymeric sleeve against the body cavity. The use of the sleeve reduces friction between the plug mechanism and body.
Each pressure balanced lubricated plug valve is composed of a sleeve and seat of polymeric sleeve seat, self-cleaning metal edge and bolted cover. It is made under strict manual operation standards, suitable for gear operator and actuator. The flange end or butt-weld end can ensure that there will be no leakage.
