This regulating valve adopts a pressure-balancing type valve core design, significantly reducing the operating torque. Combined with a high-precision guiding system, it achieves a regulation accuracy within 0.5%. The unique low-temperature compensation structure effectively counteracts the material shrinkage effect, ensuring stable performance across the entire temperature range. The valve internals are treated with a special surface treatment process, increasing the wear resistance by more than three times.

RAYS single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
The CN700 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.
