ZJHS Pneumatic Piston-Type Control Valve
The ZJHS pneumatic piston-type control valve consists of a ZSA(B) spring-loaded piston actuator and a compact single-seat (cage) valve body. It features a lighter, more compact structure with greater thrust, though its sensitivity is slightly reduced. When paired with an electro-pneumatic or pneumatic valve positioner, the pneumatic piston-type control valve enables automatic regulation of process pipeline fluids. It is widely used for maintaining precise control of process parameters—such as pressure, flow rate, temperature, and liquid level—in gases, liquids, and steam at specified values.

Product Details

The pneumatic piston-type control valve features a balanced plug design, offering high allowable differential pressure, excellent vibration resistance, low noise, and superior stability. It allows for easy installation and removal, and the required allowable differential pressure can be achieved by selecting different spring ranges. This valve is suitable for industrial process automation systems requiring low noise, high operating differential pressure, restricted installation space, or rapid response times.
