The jacketed structure facilitates online maintenance. Without the need to dismantle the pipeline, the valve seat or sealing parts can be quickly replaced, significantly reducing maintenance costs. The fixed ball design reduces valve ball wear, and in combination with the low-torque valve stem bearing system, the operation is lightweight and has a long lifespan. The ultra-low temperature adaptability is verified through material optimization and structural simulation, avoiding cold flow phenomena; the bidirectional metal sealing structure maintains sealing integrity under high pressure differences. The overall design takes into account both lightweight and high strength, supporting electric, pneumatic or manual drive, meeting the requirements of automated control, and suitable for deep cold environments with high safety requirements.

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.
RAYS pig valve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
The Axial Flow Check Valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
