The structure characteristics of once-through pneumatic diaphragm valve

overview of once-through pneumatic diaphragm valve:
once-through pneumatic diaphragm valve is dedicated to control of corrosive or general corrosive medium, surface without lining pneumatic valve body cavity or covered with a selection of all kinds of rubber, suitable for different working temperature and fluid lines. Applicable temperature: ℃ or less and ℃ or less and ℃ or less ( According to the lining and diaphragm material) 。 Pressure levels: PN. 、. 、. 。

the structure characteristics of once-through pneumatic diaphragm valve:
pneumatic diaphragm valve is a special kind of stop pneumatic valve;
and the opening of the elastic sealing parts, ensure no leakage;
and streamlined flow channel, make the small pressure loss;
no stuffing box, so there is no leakage;
separated by a middle diaphragm, pneumatic valve body and cover, that at the top of the pneumatic diaphragm valve, pneumatic valve stem parts not eroded by the medium;
, the diaphragm can be replaced, maintaining low cost.
and the diversity of the lining material, can be applied to all kinds of medium, and it has good corrosion resistance.
