G&O SERIES BUTTERFLY VALVES
Hand and pneumatic operated butterfly valves are quick opening valves
that consist of a metal disc (lined where necessary) 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 replaceable 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.
