The Power Plant Check Valve has low fluid resistance, and the internal medium passage of the valve body is straight. When the medium flows through the stop valve, its flow direction does not change. It adopts self-tightening pressure sealing, and the two ends of the valve are usually welded connections. The valve disc closes quickly, the water hammer pressure is small, the shape structure is simple, the manufacturing process is good, the sealing performance is good, and the sealing surface is less eroded when fully open. It has a wide range of applications.

Y-Type Check Valveis a type of valve used to prevent fluid backflow, named after its Y-shaped valve body. It allows fluid to flow in one direction, and when the fluid flows in the opposite direction, the valve automatically closes to prevent backflow.
The Double Eccentric High-Performance Butterfly Valve is a new type of butterfly valve designed based on absorbing the advantages of several different structural butterfly valves. The sealing surface of the valve plate of this valve is a - spherical arc surface. The sealing mechanism achieves a true dynamic seal through system pressure, thus having reliable sealing performance and durability. It has a small volume, light weight, wide manufacturing range, and is easy to maintain and repair. Due to the design of the double eccentric butterfly plate, combined with a single piece of flexible lip-shaped sealing seat, it is suitable for valves in situations requiring reliable sealing and good regulating characteristics. It can be used for quick shut-off or regulating flow.
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.
