Air actuated butterfly valves with double acting or spring return
function
General purpose valve with an EPDM liner, offering a long life with
low maintenance. Self-lubricating bearings ensure perfect guiding
and turning of the shaft without seizure or premature wear.
These valves are supplied completely assembled with either single
(spring return) or double acting pneumatic actuators.
All valve and actuator packages are tested and issued with
certification confirming the actuators functionality before
dispatch.
