2017 wholesale priceRubber Flap Valve - Pneumatic ventilation butterfly valve – Jinbin Valve Detail:
Pneumatic ventilation butterfly valve
The structure of the ventilation butterfly valve is welded with the midline butterfly plate and short structural steel plate, so there are no connecting rod, bolt and other components in it, so there will be no component problems in the process of use, so the failure rate is very low. It’s very convenient to use. It is a reliable valve device.
Because the clearance between the butterfly plate and the valve body of the ventilation butterfly valve is large and there is enough expansion space, it can effectively prevent the thermal expansion and cold contraction caused by temperature changes during use, and the butterfly plate will not be stuck.
Because of the wide selection of materials, this ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is very long.
