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, is lightweight, and has simple equipment. Pneumatic small flow control valve features small size, lightweight, high performance, precise control for small flow rates, etc. When adjusting unclean media, blocking jams should be taken care of about the problem of small throttling clearance. The pneumatic small flow control valve is particularly suitable for the central flow adjustment of liquids, steam, and other media.
