Stainless steel electric triple eccentric butterfly pneumatic valve picture adjustment

Electric pneumatic valve adopts triple eccentric butterfly triple eccentric structure, make the pneumatic valve seal in as little as possible to reduce the friction in the process of opening and closing, at the beginning of the pneumatic valve plate rotating moment face out completely, so as to realize without sealing seal, greatly improve the service life of pneumatic valves, and make the size of the opening and closing torque had significantly improved.


electric triple eccentric adjusting torque pneumatic valve pneumatic butterfly valve rod through the butterfly plate pass directly to the sealing surface, thus put an end to the open ordinary common jump phenomena in the pneumatic valve. This means that the electric pneumatic valve almost triple eccentric butterfly can start from zero opening into the regulatory regions, until 90 opening. Than the normal regulation is 2 times more than general pneumatic valve adjustment, regulation than a maximum of 100: more than 1.



electric pneumatic valve structure principle of triple eccentric butterfly:


1. Pneumatic valve shaft center and pneumatic valve plate sealing surface to form a deviation,

2. Pneumatic valve shaft center and the center line of the pneumatic valve body to form an offset,

3. The center line of the pneumatic valve sealing surface and the center line of the pneumatic valve form an offset.

electric triple eccentric adjusting control pneumatic valve fully open, the butterfly plate thickness is the only medium resistance, thus produced by the pressure drop is small, so has good flow control characteristics, especially suitable for used to adjust flow.
