● Low Torque Floating Seat: The valve uses a floating seat with O-ring seals for easy and efficient bidirectional sealing. It requires only half the usual operating torque, making it easy to open and close.
● Dual PTFE and Metal Seals: The seat incorporates a PTFE sealing ring for dual protection with both PTFE-to-metal and metal-to-metal sealing capabilities. It also helps clean debris from the gate.
● Grease Injection for Sealing: Equipped with a grease valve, the valve allows grease to be injected directly to the seal, achieving zero leakage.
● Flow Guiding Hole Design: The gate includes guiding holes to protect the sealing surface from media erosion, ensuring a perfect seal at all times.
● Low Flow Resistance and Pigging Capability: With a straight and smooth channel when fully open, the valve offers minimal flow resistance and supports pipeline pigging.
● Easy Maintenance and Low Leakage: Features a self-sealing packing structure that requires minimal adjustment and has an auxiliary sealing grease injection for guaranteed zero leakage.
● Self-Relieving Seat: Automatically relieves high pressure inside the valve when closed for added safety.
● All-Weather Actuator: Comes with fully enclosed, weather-resistant actuators suitable for all conditions.
● Position Indicator: Includes an indicator to show whether the valve is open or closed.
● Reliable Seat Design: Features a dual soft seal structure and multiple sealing rings for enhanced reliability.

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.
