Diaphragm valve with corrosion resistant lining body and corrosion resistance of the diaphragm instead of valve core component, using the movement of the diaphragm regulating role. Diaphragm valve body material USES cast iron, cast steel, or cast stainless steel, and in a variety of corrosion or wear resistant lining material, rubber and ptfe diaphragm material. The lining of the diaphragm corrosion resistance is strong, applicable to strong corrosive medium such as strong acid, strong alkali. Diaphragm Industrial Valves has simple structure, small fluid resistance, flow capacity than other type with the specifications of the Industrial Valves; No leakage, can be used for high viscosity and the adjustment of the suspended particles medium. The diaphragm isolating medium with cavity on the stem, so there is no packing medium will not leak. However, as a result of the limitation of the diaphragm and lining material, pressure resistance, low temperature resistance, generally applies only to 1. 6 mpa nominal pressure and under 150 ℃. Diaphragm valve flow characteristics close to the quick opening feature, approximate to linear before 60% of stroke, 60% after the flow rate change is not big. Pneumatic diaphragm valve can be attached in the form of feedback signal, stop and locator device, to meet the needs of the automatic control, program-controlled or adjust the flow. Pneumatic diaphragm valve feedback signal using non-contact sensor technology. The product adopts the diaphragm to promote cylinder, replace the piston cylinder, ruled out the piston ring is easy to damage, caused by leakage and cause can't promote the disadvantages of the Industrial Valves opening and closing. When air failure occurs, well the handwheel makes the valve opening and closing operation.
Over the years, has become very popular as more and more people are trying it out.

But we do think that reckoning with supply chains of flow control valve is a really important step. Even super simple switches in material, or sourcing, or shipping, or worker benefits seems like good place to start.
