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.

RAYS PDS Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.
RAYS Three-Way and Multi-Port Ball Valve are important components in fluid control systems and are widely used in various industrial fields. They are variants of ball valves. Their design allows fluids to be distributed or converted between more than two pipes. The three-way ball valve has three interfaces, which can realize the diversion, confluence or switching of fluids. According to the different internal structures, it is divided into L-type and T-type. The L-type can only connect two mutually orthogonal pipes, and cannot simultaneously maintain the interconnection of the third pipe, and only plays a distribution role; the T-type can make three orthogonal pipes interconnected and cut off the third channel, playing a diversion and confluence role. The multi-way ball valve is an extension of the three-way ball valve, with more interfaces and more complex fluid control functions.
The Throttle Stop Valve is mainly composed of valve body, valve cover, valve flap, and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals to move it up and down along the valve stem axis to realize the full-opening, full-closed movements and regulating traffic functions. The force applied by the hand wheel can be obsessed with the valve seat to reach the sealing state; Location, change the cross-sectional area between the valve petals and the cover of the valve seat, and achieve the purpose of regulating media flow. At the same time, the throttle stop valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the life of the valve.
