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.

When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
