● 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.

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 hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
