The plug valve is an indispensable and important component to connect the high pressure manifold during the cementing and fracturing operation of the oil field. It is also used with similar high pressure liquid control.The product is compact, easy maintenance, small torque, open quickly, operation effort, cementing, fracturing manifold is the best valve.
Working principle and structure characteristic:
■ plug valve mainly by the valve body, hand wheel, plunger and other components.
■ Plug inlet and outlet are 1502 by the form of connection (also can be customized according to customer demand), the valve body and the liner for the cylindrical tie between, and through the lining of the outer ring inlaid into the seal seal.
