High-pressure, low-torque plug valve with Fig 1502 integral union ends, suitable for high-pressure oil/gas manifolds in well service, cementing, and fracturing operations.
Plug valve is necessary part that is applied to high pressure manifold in well cementing to fracture service, also selected for high pressure fluid control system. It is excellent for its compact structure, easy maintenance, low torque, and rapid operation, which make it to be the most ideal valve for cementing and fracturing manifold.
