Double safety structure of valve stem: In order to prevent sudden accidents caused by valve stem damage or flying out due to unknown
reasons, independent valve stem flying prevention mechanisms are designed at the upper and lower ends of the valve stem, which fully
complies with standard API 609 and safety requirements for use.
Two-way sealing elastic valve seat:The valve seat adopts a flexible lip sealing ring elastic structure, which can automatically adjust when the
temperature and pressure change to ensure that the sealing performance of the valve is not affected;This structure can achieve two-way
sealing and meet the standard of no bubble leakage.
Internal travel limit: Minimize the probability of valve seat damage and extend the service life of the valve seat.
Fireproof and anti-static structure (optional):Can Effectively protect the safety of equipment and personnel, reduce the probability of
accidents, and improve the safety factor of the site.
High-strength one-piece valve stem: The high-strength, integral valve stem design ensures effective torque transmission and maintenance of
sealing. At the same time, the valve stem head is standardized and has the characteristic of being able to replace the actuator.

Additionally, the valve is equipped with an automatic self-cleaning feature that removes deposits during operation, ensuring reliability and stability over long-term use. Ideal for both new projects and upgrades of existing systems, the RAYS Double Disc Slab Gate Valve-Ethylene is a perfect choice for enhancing productivity and safety.
The high-temperature ball valve is a special type of valve designed for high-temperature and high-pressure environments. It can effectively control the on-off of high-temperature and high-pressure fluids. It can operate stably under harsh conditions and meet the precise control requirements in industrial production processes. It is widely used in the petroleum, chemical, natural gas, and power industries.
The structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
