Cast Steel Fixed Ball Valve 7

Description

Cast Steel Fixed Ball Valve 7

The Cast Steel Fixed Ball Valve 7 is engineered to provide reliable flow control and isolation in demanding process environments. With a robust cast ASTM A216 WCB steel body and pressure ratings up to Class 2500, this valve accommodates pipe sizes from DN 50 to DN 700, delivering strong structural integrity in steam, water, oil, and gas systems. As a cast steel fixed ball valve, its precision-machined ball remains fixed between dual seat assemblies, ensuring stable sealing and low actuation torque—ideal for high-pressure and high-viscosity applications where consistent performance is essential.

Designed to meet API 6D, ASME B16.34, and ISO 17292 standards, the valve is available in both full-bore and reduced-bore designs, allowing versatility across different flow control requirements. Seats are offered in PTFE or reinforced materials to ensure bubble-tight sealing even after prolonged thermal cycling. The cast steel construction adds robustness against pipeline thrust, vibration, and mechanical strain, making this valve a reliable choice for heavy-duty industrial applications. Safety features include anti-static devices, blow-out-proof stems, and live-loaded packing to prevent fugitive emissions and improve seal longevity.

Each valve undergoes stringent pressure and leakage testing according to API 598 and EN 12266‑1 before delivery, ensuring performance consistency—critical in power plants, chemical plants, water treatment facilities, and refineries. Its quick quarter-turn operation and low-torque design make it superior to conventional gate and globe valves in emergency shutdown or control scenarios.

The valve accommodates manual lever actuation or can be fitted with worm-gear, pneumatic, or electric actuators via the ISO 5211 mounting pad. Three-piece body construction allows inline maintenance—eliminating the need to remove the valve from the pipeline for seat or seal replacement. End connection options include butt-weld, socket-weld, or ANSI B16.5 flanged ends, enabling seamless integration into both new installations and existing systems while maintaining leak-free integrity.

Suitable for operating temperatures ranging from sub-zero up to 150 °C with soft seats, and higher when equipped with optional metal seats, this cast steel fixed ball valve adapts to many industrial processes. These include steam distribution lines, petrochemical and hydrocarbon service, compressed air networks, and water treatment processes where safe and efficient containment is vital.

Engineers favor fixed-seat designs in processes with abrasive or viscous media for their secure sealing and minimal seat wear. The Cast Steel Fixed Ball Valve 7 combines the reliability of forged designs with the adaptability of cast components, ensuring longevity and consistent performance in heavy-duty service.

Its blend of rugged cast steel construction, full or reduced-bore configuration, and inline serviceability provides a low-cost, easy-to-maintain solution for high-pressure systems. With robust sealing, fast operation, and industry-standard certifications, this valve is ideal for engineers aiming to reduce downtime and improve lifecycle efficiency.
