The swing-type valve disc design is combined with a low-inertia structure to ensure rapid closure and reduce water hammer effects, thereby enhancing system safety. The sealing surfaces of the valve seat and valve disc are treated with hardening or PTFE composite materials, which adapt to the ultra-low temperature contraction characteristics and maintain long-term sealing performance. The optimized flow path design reduces pressure loss, improves the efficiency of medium flow, and simultaneously reduces the risk of icing. The overall structure is compact, supporting horizontal or vertical installation, meeting the requirements of different pipeline configurations, and suitable for high-demand applications of one-way cutoff for deep-cold media.

The dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
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 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.
