Adjustment of extension rod pneumatic valve is introduced

butterfly pneumatic valve is suitable for the temperature of extension rod ~ ℃ or less such as food, medicine, chemical, petroleum, electric power, textile, paper and other water supply and drainage, for adjusting flux on the gas pipeline and the role of intercepting medium. Its main characteristic is:
, novel design, reasonable, unique structure, light weight, rapid opening and closing.
, small operation torque, easy to operate, saving smart.
, can any position installation, maintenance is convenient.
, seal can be replaced, sealing reliable performance to achieve two-way sealing zero leakage.
weak, sealing material ageing resistance, resistant to corrosion, long service life, etc.
