Category : Electric butterfly valve

Product Name : Gas Low-load Electric Butterfly Valve

Product introduction:
As a gas modulation device & a two-way switch device gas low-load electric butterfly valve is suitable to ventilation and dust removing pipeline in the industrial fields of metallurgy mineral cement chemical-engineering power device industrial furnace and so on.
*Small driving torque, flexible opening and closing without friction, convenient operation, long service life of valve.
*Can be install in any orientation, not affected by the flow direction.
*The new type of structure is designed and manufactured by using the midline plate and short structure steel plate welding, to avoid the influence of high temperature expansion, easy to operate.
*Suitable for switching off and flow regulation in ventilation system, air conditioning system and high temperature flue gas.


 

PRODUCT CHARACTERISTICS

 
(1) Valve body valve plate are made of welding steel plate light weight simple structure and easy installation.

(2) Butterfly plate and valve body expansion gap can effectively prevent the phenomenon of freezing caused by thermal expansion.
(3) No connecting rod bolts reliable work effectively extend the service life.
