Pneumatic Sleeve Regulating Valve
The Pneumatic Sleeve Regulating Valve is a high-performance control valve designed for precise flow, pressure, temperature, and liquid level regulation in industrial process systems. It adopts a sleeve-guided structure, providing excellent stability, high control accuracy, low vibration, and extended service life under demanding operating conditions.
The valve is actuated by a pneumatic diaphragm or piston actuator and can be equipped with valve positioners, limit switches, solenoid valves, and other intelligent accessories to achieve automated process control. It is widely used in industries such as petrochemical, chemical processing, power generation, oil & gas, water treatment, metallurgy, and pharmaceuticals.
As a professional valve manufacturer, we provide comprehensive OEM and ODM services to meet diverse customer requirements.
