● The valve body, made from high-quality materials, includes a ball test fitting and has its middle flane and neck bolted together.
● The valve seat has a single-piston effect for both upstream and downstream flow and features a Double Block and Bleed (DBB) function.
● Between the valve seat and the ball, there are three types of seals: a traditional soft seal, a triangular ring seal, and a hard seal.
● The valve stem includes safety features to prevent it from being ejected if operated improperly.
● The valve is equipped with devices to enhance fire safety and prevent static buildup.
● Emergency sealant injection ports are available for the valve seat seal and stem seal. These are used for repairs in case of leakage, and each port has a grease valve and a check valve.
● The valve has both drainage and venting ports. The drain valve is at the bottom for emptying and venting the cavity, and the vent valve is at the top for cleaning.
● This valve is compatible with various types of actuators, including manual, electric, and hydraulic.
● Valves with welded ends can have their materials adjusted to match the pipeline, ensuring proper welding. Sleeve extensions prevent interference with sealing during welding.
● Underground valves have extended stems to make above-ground operation possible, with accessible grease, drainage, and venting facilities. The stem height is customizable.

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.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
Cryogenic Gate Valve is an opening and closing device used for fully opening and fully closing. The opening and closing component of ultra-low temperature gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape, and the wedge angle varies with parameters.
