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.
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.
The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
