●The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.
●Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature differences, ensuring a reliable seal.
●The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.
●It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.
●The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.

Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
There is an oil groove between the valve body and the sealing surface of the pressure-balanced plug valve, and sealing grease can be injected into the valve seat through the oil nozzle at any time to improve the sealing performance. The material of the parts and the size of the flange can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
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.
