CS702 Small-size Cage-guided Control Valve
The CS702 Small-size Cage-guided Control Valve is a high-performance single-seat regulating valve, suitable for high-pressure differential situations where the liquid pressure difference exceeds 3 MPa. It is widely used in self-control systems of industries such as petroleum, chemical engineering, metallurgy, power stations, air separation equipment, liquefied natural gas, etc. The sturdy valve core guide and sleeve can prevent liquid from undergoing flash evaporation and cavitation. The valve body has an S-shaped streamlined channel, with low pressure drop loss, large flow rate, and a wide adjustable range.

CH702 High-pressure Cage-guided Control Valve
The CH702 High-pressure Cage-guided Control Valve is a pressure-balancing type regulating valve. This valve is widely applicable to high-pressure drop scenarios that require good dynamic stability, low noise, and minimal cavitation corrosion. The fluid passage of the valve body is in an S-shaped streamline, resulting in low pressure drop loss, large flow rate, and a wide adjustable range.
CJ702 Jacketed Cage-guided Control Valve
The CJ702 Jacketed Cage-guided Control Valve is a derivative product of the C702 cage-type control valve. When the crystallization temperature of the regulated medium is higher than the normal temperature, or due to the decrease in temperature and the increase in fluid viscosity or solidification, the valve fails to operate properly, the valve can be heated and insulated with steam to prevent material crystallization and solidification, avoiding valve blockage and reducing the power consumption of the project. This valve not only has the advantages and applications of the CJ702 cage-type control valve, but also has the function of insulating the regulated medium.
CT702 Cage-guided Control Valve with Pilot
The CT702 Cage-guided Control Valve with Pilot is a pressure-balancing type control valve. The valve internals adopt a sleeve-guided pilot-type valve core. It is suitable for controlling high-pressure differential fluids at various temperatures. The valve core moves rapidly by utilizing the pressure of the fluid, with low operating force. The sealing type is a single-seat seal, and the accuracy of the flow characteristic curve is high. The dynamic stability of the control valve is good, the noise is low, and it is dust-proof.
This series of products features a compact structure, small size, and S-shaped fluid channels. The valve core adopts a pressure-balancing structure, with high accuracy of the flow characteristic curve and the ability to achieve a larger CV. It can be quickly replaced, is stable and reliable, and is easy to maintain. A smaller actuating force can control a high pressure difference. There is a sealing ring between the valve core and the valve cage, significantly reducing the leakage. It is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a large thrust, strong steel strength, sensitive action, high-precision positioning, fast response, convenient and sturdy, and a long service life.
Developed with principles of standardization, universality, modularity, and interchangeability. Valves of different sizes maximize part interchangeability, universality, and ease of maintenance. This ensures low operational costs.

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.
Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
