Frontline Services

Cost for actuator maintenance and repair increases with the age and wear of the actuator. Retrofitting is a process of auditing old actuators and re-automating them with controls. This ensures that your plant is more efficiently controlled, and any changes due to age and wear are addressed. We offer a complete bolt-on package for name brand actuators, while the actuator is in place, without any service interruption. We can also replace hand pumps, high pressure controls, limit switches and poppet blocks. If the audit shows that replacement is not necessary, we have spare kits for pumps and poppets.

ATI/Gevalco “Gas Motor Control” package can be used to upgrade existing EIM “G” series gas motor actuators with current, more reliable technology. The control package utilizes current “poppet” valve technology to provide reliable, maintenance-free control of gas motor actuators. The standard local “auto-manual” control consists of a “poppet” selector valve and two limit valves. The Gevalco patented limit valves, operated through a reliable cam mechanism, use 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 provides 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. The components can be easily field installed and calibrated to provide reliable, long cycle life control of existing gas motor actuators.

The ATI/Gevalco Advantage

• Bubble tight “poppet” design eliminates the seal cutting problem associated with the existing spool valve design.
• Valve material is marine-grade, hard-anodized aluminum and stainless steel for maximum corrosion resistance and longer cycle life.
• Built-in pilot pistons provide signal input from other solenoids or pneumatic devices.
• High flow exhaust shuttle valve improves motor efficiency while reducing gas consumption.
• Commercially available 3-way SS ball valve for local manual operation.
•  Optional limit switches with (2) explosion proof SPDT hermetically sealed proximity switches for remote indication.
•  Optional remote electric operation with (2) 2-way explosion proof solenoids.
•   Unit comes pre-tubed for an easy bolt-on; Connect power gas and go.

ATI customizes valve automation solutions to meet our customers’ specific needs. Almost 20 years ago, our story began with proprietary technology in customizing linear actuators. Those signature series actuators helped ATI build a strong reputation in the flow control industry. Paying attention to engineering specs became our core competency.  Since that time, ATI has expanded our customization to include automation solutions when power is not readily available, controls for fast speeds, modulations or special conditions, and actuators for the pipeline industry. We have the experienced technicians, as part of ATI FrontLine Services, to repair or provide startup for on-site installations.
