● Excellent fire and flame retardant performance: The valve is made of high-quality stainless steel, brass or Monel alloy and other materials, with good flame retardant and electrical conductivity.
● Oil-free design and cleaning requirements: All components are strictly degreased during the manufacturing process to ensure that there is no oil, the surface is smooth and no burrs, and the high cleaning standards for oxygen delivery are met.
● Compact structure, safe and reliable: the valve has compact design, fast heat transfer, easy operation, excellent sealing performance and long service life.
● Low torque operation: Valve with low torque design, flexible operation, reduce mechanical friction, reduce the risk of ignition.
● Fire safety Certification: compliant with API 607 and API 6FA fire safety standards.

An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
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 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.
