Zjhy Pneumatic Small Flow Control Valve - China

ZJHY Pneumatic small flow control valve

Pneumatic small flow control valve product description

ZJHY pneumatic small flow control valve is a product developed independently by our company for small flow conditions.

It consists of a pneumatic diaphragm actuator and a small flow control valve body.

The multi-spring actuator has a low height, light weight, and simple equipment.

Pneumatic small flow control valve features small size, light weight, high performance, precise control for small flow rates, etc.

When adjusting unclean media, the problem of blocking jams should be taken care of with regard to the problem of small throttling clearance.

Pneumatic small flow control valve is particularly suitable for the main flow adjustment of liquids, steam and other media.
