Q: the composition and principle of diaphragm valve introduce a: the diaphragm valve with corrosion resistant lining body and corrosion resistance of the diaphragm to replace the valve core component, using the movement of the diaphragm has regulation effectiveness. The diaphragm isolating medium and cavity on the stem, so there is no packing media will not leak. When air failure occurs, well the handwheel makes the valve opening and closing operation. 。 Pneumatic diaphragm valve feedback signal right and using non-contact sensor technology. The diaphragm valve has simple structure, small fluid resistance, flow of Marine valve is experienced with the specifications of the other type Industrial Valves is big; No leakage, can be used for high viscosity and the suspended particles of the medium. The product right and the use of diaphragm to promote cylinder, replace the piston cylinder, dispense with the piston ring is easy damaged, cause leakage and cause there's no way to push the valve opening and closing of ills. The lining of the diaphragm corrosion resistance is strong, suitable for use in the regulation of acid, strong alkali, strong corrosive medium. However, because the diaphragm and lining material limit, pressure resistance, low temperature resistance, ordinary only suitable for use in 1. 6 mpa nominal pressure and under 150 ℃. The way of pneumatic diaphragm valve can be attached feedback signal, stop and locator device, in order to suit the requirements of automatic control, program-controlled or adjust the flow. Diaphragm valve flow especially close to the nature of the nature of the quick opening special, before 60 one hundred percent stroke approximate to linear, small as changes in the flow after 60 to one hundred percent. Diaphragm valve body material see fit and use of cast iron, cast steel, or cast stainless steel, and in a variety of corrosion or wear resistant lining material, rubber and ptfe diaphragm material. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
