C700 Series Single Seated Control Valve is a top-guided structure control valve, used in equipment that can achieve air opening or air closing. The fluid channel of the valve body is in an S-shaped streamlined shape, featuring low pressure drop loss, large flow rate, wide adjustable range, high accuracy of the flow characteristic curve, large guiding area of the valve core, and good vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which features a compact structure and large output force. It can be used to control various fluids with different pressures and temperatures.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
The Axial Flow Check Valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
