HTHP Slab Gate Valve has small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure self-tightening seal is adopted, and the two ends of the valve body branch pipe are usually welded. 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 application is wide. The phenomenon of water hammer is not easy to produce due to the long closing time. The medium can flow to either side in any direction, easy to install.

The Cryogenic Gate Valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
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.
