The cast carbon steel top mounted ball valve is designed specifically for fluid isolation and is finely crafted to achieve precise fluid isolation in various pipeline systems. The valve adopts a top installation design, which is easy to maintain online and greatly reduces downtime, ensuring the continuous operation of the system. Its cast carbon steel structure exhibits robustness and durability even in high-pressure and harsh environments.
Valves equipped with anti-static devices can prevent static electricity accumulation, which is particularly important in hazardous systems. O-ring provides a safe and leak proof seal, preventing any liquid leakage and ensuring safe operation. In addition, self exhaust valve seats and soft valve seat inserts can improve sealing performance under various pressure conditions, ensuring reliability and safety during operation.
● Antistatic Device:Prevents the accumulation of static electricity, thereby improving the safety of operation in flammable environments.
● O-Ring Seals: Offer reliable and leak proof sealing, achieving safe and efficient fluid isolation.
● Soft Seat Insert: Improves sealing ability, ensures tight closure, and reduces the possibility of fluid leakage.
