Material cast iron brand G6B41F product alias diaphragm valve applicable scope environmental protection, industrial connection form flange nominal diameter 15 ~ 200 (mm) pressure 0.6 (Mpa)
The compact small pneumatic piston diaphragm regulating valve consists of a diaphragm valve and a pneumatic actuator. It is powered by compressed air and regulates the flow of fluid medium in the process piping. The closing and opening of the diaphragm valve is achieved by the pressure from the line acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down, closing the valve passage. When the control chamber pressure is discharged to the atmosphere or the downstream pipeline, the diaphragm rises and the valve passage is opened. The valve does not have a valve stem, a gasket, an orientation seat, etc. The only component that moves in the channel is the diaphragm, so there is no rust and lock, and it has higher stability. A variety of structural forms and control forms are available for a variety of fluid control needs.
   Due to the structural use of the corrosion-resistant lining valve body and the corrosion-resistant diaphragm, the no-filler structure, the throttling element is the elastic diaphragm, and the valve body flow path is smooth, the pneumatic diaphragm valve has a small force and a large flow rate. No external leakage and convenient, reliable, fireproof and explosion-proof advantages, widely applicable to the flow regulation of strong acid, strong alkali, strong corrosion, high viscosity, containing granules, fiber with toxic and non-contaminated media in industrial automation systems
