Pneumatic High Pressure Low Flow Control Valve

Pneumatic High Pressure Low Flow Control Valve

Pneumatic small flow control valve is a small diameter regulating valve specially developed for small flow regulation.Small flow control valveis a micro control valve customized for certain special working conditions.The micro flow control valve is made of forged valve body, and is easy to be made into ahigh pressure low flow control valve.

The pneumatic low flow control valve is small in size, light in weight, high in performance, and is used for accurate control of minute flow. For example, in precision chemical and scientific research institutions, it is used to precisely control the flow rate and pressure.

3. High pressure resistance, up to 32MPa;
4. The valve plug is diversified and the adjustment performance is good;
5. Small size, light weight and easy to install;
6. The control accuracy is high, and the small flow rate can also be adjusted normally. The small control CV reaches 0.001.

The Dimensions of High Pressure Low Flow Control Valve:

Kind notes when applying the small flow control valve:

When control the dirty medium, it should be concerned with the problem of small interception gap, and pay attention to prevent the occurrence of jamming. If necessary, add a filter or strainer in front of thesmall flow control valveto ensure the smooth passage of the medium. With thelow flow control valveused by the positioner, the positioner does not work properly, and the blockage of the air passage throttle is the most common fault. Therefore, when working with the positioner, the air supply must be handled. The usual method is to install an air filter pressure reducing valve on the air supply line before the positioner.
