Bettis GVO-C Linear valve actuator has been designed to meet a wide variety of
applications. It has been manufactured to close tolerances and specifications and has
been factory inspected and tested prior to shipment. Each actuator is identified with a
unique serial number for reference when ordering replacement parts.
The actuators have a special feature: they are single-acting, spring-return, to provide
“Fail-Close” or “Fail-Open” action in case of loss of air pressure or electrical power.
The springs are located in a factory sealed canister, easy to remove and provide high
safety standards during the operation and maintenance.
Each actuator was engineered to meet and exceed your specific application
requirements.
The following guidelines are designed to help you with your maintenance procedures.
