Product Details

Control valve is contacted directly with the medium in the pipe, the valve trim act in the valve body,to change the flow area between the valve trim and the valve seat, which change the drag coefficient of the valve, thereby adjusting the process parameters.

The action way can be divided into positive way (air to close type) and back way(air to open type).The valve will be from fully open to fully close when input signal pressure change from down limit value to upper limit value;The valve will be from fully close to fully open when input signal pressure change from down limit value to upper limit value;

ZXN series Pneumatic double seat Control Valve Characteristics:

Pneumatic Diaphragm Single Seated/Double Seated/Sleeve Control Valve is composed of multi-spring adjustable diaphragm  actuator and single seat/double seated/sleeve control valve. This valve is lighter than ordinary double seated control valve while its outlook is nice. By using balanced valve core, differential pressure is large, flow rate is big, which is suitable for low requirement of leakage.Size Range: DN25-DN300 Pressure: 1.6 - 6.4MPA
