Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
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 cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
