Pneumatic Actuated Ball Valves, API 6D, A216 WCB, Customized

Product Name: Pneumatic Actuated Top Entry Ball Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: Customized
Pressure: Customized
End Connection: RF
Operation: Pneumatic Actuator

Our top-entry trunnion ball valves provide an optimal solution for both offshore and onshore applications. Designed for ease of operation and maintenance, they allow convenient in-line disassembly for trim inspection and internal repairs, even in space-constrained environments. These valves offer exceptional corrosion resistance and reliable sealing performance across a wide pressure range. Manufactured as a single forged or cast piece, they feature two independent seats for bi-directional sealing. Each valve is engineered to meet customer-specific requirements while adhering to international standards.
