Hand and pneumatic opera - ted butterfly valves are quick opening valves that consist of a metal disc (lined where neces - sary) with its pivot axes at right angles to the direction of flow in the pipe. They are leaktight on all liquids, slurries, granular materials, powders, pastes, gases acids etc... Seat and disc are easily repla - ceable without any special tools. The wide range of available elastomer materials enables an appropriate selection for each application and is a guarantee of perfect resistance to corrosion and abrasion.
