The plug valve is wellhead valve and conformed with API 6A specification. High pressure plug valve is a very important fitting for cementing, well cementing and crushing and is also applicable to control other high pressure fluid. Plug valve is combined by valve body, seal arcing segment, plug cock, etc.
The low torque and high pressure plug valve designed and manufactured by our company are all made by high quality and high strength structural alloy steel. Strict heat treatment ensures even metallographic structure and loading capacity. The materials completely conform to USA ASTM and AISI standards and products technical index fully matches with API Spec 6A standard. Product joints can be connected by joint thread, pipeline thread, butt welding or non-pressure sealing end;
There buckle models are provided for the terminal of plug valve: union plug valve, LP female connection and LP external thread. In according to users’ needs, we can design the high pressure plug valve with a base;
High pressure plug valve has different specifications: 1’’, 2’’, 3’’ and different cold working pressures: 42Mpa(6000Psi),70Mpa(10000Psi),105Mpa(15000Psi). Plug valve and maintenance package used under normal temperature, low temperature and sulfurous gas environment are available.
