Imported pneumatic low flow regulating valve
(Air-Powered Micro Flow Control Valve, Air Flow Regulation Valve, Feed Additive Device Flow Regulation Valve)
Section 1: Import Pneumatic Low Flow Regulating Valve Product Overview
Germany VordWODEOur imported pneumatic micro flow control valve, also known as the pneumatic small flow control valve, is a product developed by Ward Company for low flow conditions. It consists of a pneumatic diaphragm actuator and a micro flow control valve body, featuring a multi-spring actuator that is low in height, lightweight, and easy to install. The pneumatic small flow control valve is characterized by its compact size, light weight, high performance, and suitability for controlling micro flows. When regulating impure media, attention should be paid to the issue of small throttle gaps to prevent clogging. The pneumatic small flow control valve is suitable for primary flow control in liquids, steam, and other media.
