The answer to problems of: corrosion, abrasion, clogging, contamination, vacuum & gas handling

Hand and pneumatic operated pinch valves do not incorporate any stuffing box and are leaktihgt on all liquids, slurries, granular materials, powders, pastes, gases, acids, etc…

Sleeve (internal rubber) is supported during opening and closing, and is 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.

G&O SERIES PNEUMATIC ACTUATORS

Piston type air operators line offer a great solution to a wide range of actuation situations. They are exclusively designed to G&O series pinch valves and can be mounted in any position. These actuators are built in aluminum and are available in three options:

• single effect acting – fail to close (air to open)

• single effect acting – fail to open (air to close)

• double effect acting – fail to open & fail to close

Single effect acting actuators are fitted by an extractable handwheel for security.
