Miniature pneumatic diaphragm control valve for import Product Overview
Germany VordeWODEImported precision miniature pneumatic diaphragm control valves, composed of a multi-spring pneumatic diaphragm actuator and a low-flow resistance miniature control valve body. The multi-spring actuator features a low height, light weight, and simple assembly. The flow channel of the miniature pneumatic control valve body isSStreamlined with compact structure, lightweight, rapid operation, minimal pressure drop loss, large valve capacity, high accuracy in flow characteristics, and easy maintenance, suitable for stringent working conditions.
Pneumatic Diaphragm Control Valve with Electric Power Supply-Air valve positioner or pneumatic valve positioner, capable of achieving automatic regulation and control of process pipeline fluid medium. Miniature pneumatic regulating valves are mainly used to maintain process parameters such as pressure, flow rate, temperature, and liquid level for gases, liquids, steam, and other mediums at given values. These miniature pneumatic regulating valves are suitable for applications where leakage is allowed to be minimal, there is not a significant pressure difference before and after the valve, and the medium has some viscosity and contains a small amount of fibers.
