The cast carbon steel top inlet ball valve used for fluid isolation is designed to provide precise fluid isolation for various pipeline systems. The valve adopts a top inlet design, which facilitates online maintenance, significantly reduces downtime, and ensures continuous operation of the system. Its cast carbon steel structure has robustness and durability in high-pressure and high demand environments.
This valve is equipped with anti-static devices to prevent static electricity accumulation, which is particularly important in hazardous systems. O-ring provides a safe and leak proof seal, preventing any fluid leakage and ensuring safe operation. In addition, the self relieving valve seat and soft valve seat insert improve the sealing performance under different pressure conditions, ensuring reliability and safety during operation.
● Antistatic Device:Prevents the accumulation of static electricity and improves the safety of operation in flammable environments.
● O-Ring Seals: Provides reliable and leak proof sealing, achieving safe and efficient fluid isolation.
● Soft Seat Insert: Enhances sealing ability, ensures tight closure, and minimizes the chance of fluid leakage.
