Pneumatic control valve is powered by compressed gas, with a pneumatic diaphragm head as the actuator, and driven by accessories such as valve positioner, converter, solenoid valve, holding valve, gas storage tank, gas filter, etc., to achieve on/off or proportional adjustment. It receives control signals from industrial automation control system to adjust various process parameters of pipeline media, such as flow rate, pressure, temperature, liquid level, etc. The characteristics of pneumatic control valves are simple control, fast response, and inherent stability, without the need for additional explosion-proof measures

Product Features:

Pneumatic sleeve regulating valve adopts sleeve guidance and pressure balanced valve core, suitable for situations with large pressure difference. By replacing the upper valve seat with a balanced sealing ring, the traditional sleeve double seat valve structure is transformed into a sleeve single seat structure, greatly improving the leakage level of the sleeve valve. The valve core utilizes a pressure balanced structure with low opening and closing force. The working condition of high pressure difference can be controlled by a smaller actuator thrust. Widely used in fluid control of medium and low temperature, medium and low pressure pipelines that require good dynamic stability. Good sealing performance and large allowable pressure difference. Sleeve guide, with a large guide area, good stability, compact structure, can quickly replace valve components online, high maintenance efficiency, and save manpower and time. The balanced valve core structure ensures that the required actuator thrust is small.
