High performance butterfly valve

Product description

Product introduction: Pneumatic high performance butterfly valve adopts the "oblique elliptical butterfly plate radial dynamic balance sealing system" to realize the butterfly plate sealing ring

The non-lubricating friction and jamming between the sealing surface of the valve seat, the pressure Angle of the sealing surface is greater than the friction Angle, so that the butterfly plate is open

The opening resistance is very low, the opening seal is separated, and the closing contact automatic sealing action is realized quickly and reliably

Butterfly valve inlet and outlet two-way seal zero leakage.
