1. Top Entry Cryogenic Trunnion Mounted Ball Valve Structure: This structure allows the valve to be maintained online, improving the convenience of use.
2. Extended Valve Cover Design: prevents condensed water from flowing into the insulation layer, ensuring the normal operation of the valve in low temperature environment.
3. Valve Stem live-loaded Seal Structure Design: This design improves the sealing performance of the valve and ensures good sealing effect under various working conditions.
4. Special Design of Valve Seat Assembly: including detachable valve seat structure to ensure reliable sealing and easy maintenance.
5. Valve Cavity Overpressure Relief Design: ensure the safe operation of the valve under high pressure environment.
6. Valve Stem Anti-settling Design: prevents the valve stem from settling during operation to ensure the stability and reliability of the valve.
7. The Extended Valve Cover Has a Drip Tray Design: it effectively prevents condensed water from flowing into the insulation layer and protects the internal structure of the valve.
8. Fire-resistant, Anti-static, and Anti-stem Blowout Functions: ensure the safe use of the valve under extreme conditions.

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.
The cryogenic butterfly body can be provided in two structural forms, namely flange connection and butt. welding connection (both with inspection ports). The body with inspection ports can replace the valve internals online, making maintenance work extremely simple, which is conducive to the rational use of resources and saving maintenance costs. The extended valve cover + drip tray design ensures that the temperature at the stuffing box is above zero degrees, so that the connection between the stuffing and the stem will not freeze and lock. Through the use of three-dimensional simulation optimization design, effective control of material changes under cryogenic conditions, selection of high-quality materials and effective processing technology to meet the stable performance of materials under cryogenic conditions. This series of valves has good sealing performance, high reliability, light weight, compact structure, and no need toworry about abnormal increase in valve cavity pressure. lt isan ideal valve for conveying cryogenic media and can bewidely used in cryogenic conditions in liquefied natural gas,aerospace and other fields.
RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
