The Power Plant Check Valve has low fluid resistance, and the internal medium passage of the valve body is straight. When the medium flows through the stop valve, its flow direction does not change. It adopts self-tightening pressure sealing, and the two ends of the valve are usually welded connections. The valve disc closes quickly, the water hammer pressure is small, the shape structure is simple, the manufacturing process is good, the sealing performance is good, and the sealing surface is less eroded when fully open. It has a wide range of applications.

Oxygen Globe Valve are often used in physical and chemical experiments with gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the system. The oxygen shut-off valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.
RAYS Blind Valve features an advanced design for quick and safe flow isolation or fluid control within pipelines. At the heart of the valve is a blind plate that can be swiftly moved in and out by turning a handwheel. To isolate the flow, simply turn the handwheel and the blind plate will slide along a track to the center of the pipe, creating a seal that blocks fluid flow. This operation does not require any special tools, nor does it involve dismantling heavy machinery or dealing with complicated bolts and nuts. The design of the blind plate ensures a stable and reliable sealing performance in any working condition, greatly simplifying the operation and reducing operational risks. The simplicity and durability of the structure also make maintenance straightforward, reducing both maintenance costs and downtime.
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.
