● 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.
● 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.

The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
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.
