Bi-direction metal seat wafer butterfly Valve

The valve is used in pipeline system where is bi-directonal tight,frequent operated and high reliability,especially in purified pipelines of food,beverage,medical and chemical and key pipelines of petroleum chemical,power station,rnetallurgy,traffic and large building acting as on-off and regulating.

The seal of bi-directional butterfly valve is high performance compound material or deposit welding alloy, which is anti-corrosive, zero leakage and has long shelf life.The unique floating seat ensures bi-directional tight and solves single seal problem of offset butterfly valve. This valvehas all the merits of triple offset butterfly valve,also has high reliable, two-way seal performance.

The connecting is wafer and lug, and the driving is worm gear, electric actuator and pneumatic actuator.Electric butterfly valve sould be noted the detailed specifications of performance requirements of electric actuator in the sales order. Pneumatic butterfly valve also should be remarked whether need solenoid directional valve, 3 air supply accessories,limit switch,manual operator,positioner or not in the sales order.
