● Frictionless Switching: The unique design prevents friction against the valve seat, reducing wear compared to traditional valves.
● Single Seat Design: This design ensures no leakage downstream and prevents pressure build-up inside the valve.
● Self-Cleaning: The media flows 360 degrees around the seal when the valve core moves away from the seat, cleaning off any debris.
● Low Torque Required: Without friction on the sealing surface, the valve turns easily.
● Durable Hard Seal: The valve core's sealing surface is reinforced with hard alloy, making it reliable even in harsh conditions.
● Double Eccentric Design: This feature combines the best aspects of various valves, handling extreme conditions like high and low
temperatures, frequent operation, and bidirectional shutoff more effectively.
● Full Bore Design: The design ensures an open, unobstructed flow path without any dead zones or build-up, eliminating the need for
pressure relief.

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 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.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
