Our valves are designed in accordance with API 6A, API 6D, and NACE MR0175 standards. The sealing surfaces of the gate and seat are coated with carbide alloy through overlay welding to enhance resistance against erosion and corrosion. We use imported lip-type composite gates and seats, along with stem seals that ensure reliable sealing, safety, and reduced operational torque. The stem’s back seal design allows for packing replacement under working pressure conditions. The valve structure offers two options: rising stem and non-rising stem, each with clear indicators for opening and closing. The gate can be either integral or split, while the seat is available in both floating and fixed types. Driving mechanisms include manual, hydraulic, and gear-driven options. Connection types support flange, threaded, and coupling configurations. Product technical specifications cover PSL1 to PSL4 and PR1 to PR2. Key technical parameters include:
