The gate valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change
its flow direction when flowing through the gate valve. The torque required for opening and closing is small, the body structure is simple, the
manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of
applications is wide. Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides
and easy to install.
Application Scenarios: The wedge valve is generally used in the shape of the valve's shape without strict requirements, but the use conditions are
more harsh. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require closure to ensure
long -term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the application of power
industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
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.
