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 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.
The C700 Series Low-Noise Control Valve is divided into the CN702 and CDN702 series, mainly designed to reduce the noise of compressible fluids. To adapt to the throttling, diffusion and expansion of gases, the valve core adopts a pressure-balanced structure, and the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The fluid passage is in an S-shaped streamline, and a deflector wing is also provided to improve the smooth flow of the fluid around the sleeve. Therefore, the control valve has low pressure drop loss, large flow rate, low noise and less cavitation corrosion. The control valve is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a simple and compact structure, stronger stability, large output force and long service life.
The Side Entry Trunnion mounted ball valves are quarter-turn valves used to stop the flow of medium in pipelines. RAYS is the real API 6D valve manufacturer for the Trunnion mounted ball valve. These valves feature a round or spherical disk in the center that rotates to start or stop the flow. This disk is called a ball and it features a hollow center. Ball valves are extremely versatile and are commonly used in industrial applications where tight shut-off is required.
