The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
The dual-plate wafer check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
