Driven by motor driving this butterfly valve actuator

2011-08-02

Driven by motor driving this butterfly valve actuator, make the dish
plate in 90 ° scope free rotation to achieve on-off or regulatory medium
flow purpose.
At present, fluorine-butterfly butterfly valve, lining rubber
butterfly valve, as a kind of used to attain a pipeline system hige and
flow control components, already in petroleum, chemical, metallurgy,
water and electricity in many areas get very widely. In the butterfly
valve technology already male know, its sealing form used more sealing
structure, sealing materials for rubber, ptfe etc. Due to restrictions
of structure characteristics, does not adapt the high temperature
resistant, high pressure and corrosion resistance, abrasion resistance,
etc. Existing a more advanced butterfly valve is triple eccentric metal
hard seal butterfly valve, the valve body and seat for conjoined twins
components, heat-resistant, seating surface layer surfacing corrosion
resistant alloy material. Multi-layer soft fold type sealing ring fixed
in the valve plate, this butterfly valve and traditional butterfly
valve, compared with high temperature resistant no friction, open the
operation of the light, closing with transmission’s torque increases to
compensate for sealing, improve the butterfly valve sealing performance
advantages and prolong the service.
