PF series parallel gate valveDetailed product description：

The PF series parallel gate valve design complies with the requirements of API Spec 6A and SY/T5127-2002 specifications. The valve structure has two forms: open stem and concealed stem: concealed stem (without tail rod) structure. Clear pole structure with balanced tail pole. The valve stem sealing packing can adopt a lip shaped structure, which is reliable in sealing and has a small operating torque. There is a reverse sealing structure between the valve stem and the valve cover, which facilitates the replacement of valve stem packing under pressure. Applied to drilling and completion systems, drilling tees, Christmas trees, tubing heads, and manifolds. Pressure bearing forging, bidirectional design. The valve plate and valve seat, valve seat and valve body, valve cover and valve body, and valve stem are all sealed with metal to metal seals. The sealing surface of the gate and valve seat is welded with hard alloy, which is corrosion-resistant and erosion resistant. The valve cover has grease injection holes. We can also produce special specifications of parallel gate valve series such as PFA, PFK, PFL, PFH, PFFY (hydraulic), etc. according to customer requirements.
