Cast carbon steel top-mounted ball valves are specifically designed for fluid isolation, featuring exquisite craftsmanship that enables precise fluid separation in various pipeline systems. The top-mounted design makes online maintenance of the valve simple, significantly reducing downtime and ensuring continuous system operation. The cast carbon steel structure demonstrates robust durability, maintaining stability even under high pressure and harsh conditions.
Valves equipped with anti-static devices can prevent the accumulation of static electricity, which is particularly important in hazardous systems. O-ring seals provide a safe and leak-proof seal, preventing liquid leakage and ensuring operational safety. Additionally, self-ventilated seats and flexible seat inserts enhance sealing performance under various pressure conditions, ensuring reliability and safety during operation.
● Anti-Static Device: Prevent the accumulation of static electricity, so as to improve the safety of operation in flammable environment.
● O-Rings: Provide reliable, leak-proof seals that ensure safe and efficient fluid isolation.
● Soft Seat Insert: Improves the sealing capacity to ensure a tight closure and reduce the possibility of liquid leakage.
