Electric actuator butterfly valve
Product introduction
COVNA series butterfly valve, unique appearance, compact structure. The 2- way seal function, not affect by the flow control. Can be used as the truncation effect, also can flow regulation, Shell using epoxy resin coating to prevent rust. Through the selection of the valve seat seal, disc material, suitable for different working medium.
