The ZMABY Pneumatic Diaphragm Low-Flow Control Valve is a compact-bore control valve specifically developed for precise regulation of minute flow rates. It enables accurate control of minute flows and features a compact structure, small size, light weight, and convenient installation and maintenance. When regulating impure media, attention should be paid to preventing blockage due to the valve's narrow throttling gap. It is widely used in main flow regulation applications for liquids, steam, and other media.
