Gas Motor Actuator Control

The Gevalco “Gas Motor Actuator Control” package utilizes hi-pressure poppet valve technology to provide reliable, maintenance-free control of gas motor actuators. The standard local “auto-manual” control consists of a pop- pet selector valve and two limit valves. The patented Gevalco “Limit Valves”, operated through a reliable cam mechanism, utilize a mechanical plunger integral to the proven Gevalco poppet valve. The poppet valve directly stops gas flow through the motor as opposed to operating a spool-type selector valve. This design pro- vides quick, positive shut-off of the actuator to eliminate excessive torque on the valve and the waste of valuable gas. The “auto-manual” station, which can be remotely located, utilizes the proven and reliable Gevalco poppet valve design to provide a compact, easy to use, local control of the valve. In addition, all of the proven Gevalco control packages, such as, Remote Electric, Automatic Station Bypass, and Line Break control modules can be provided for operation with the Gevalco “Gas Motor Actuator Control” module.
