The Zero Emission Electro-Hydraulic actuator (photo) provides a comprehensive solution to lower emissions without requiring pipeline gas as the actuator’s primary power supply. Pipeline actuators have previously relied on using the gas from the pipeline as a power source, which is then emitted into the atmosphere. With the self-contained Zero Emission Electro-Hydraulic solution, the power source is attached to the actuator in a compact platform. Available in spring-return or double-acting configurations, the Zero Emission Electro-Hydraulic package can be mounted directly to the valve via flange or custom connection. The pump, motor, reservoir limit switches, solenoids and positioners are mounted to the actuator. In remote locations where power is not available, solar power systems can be applied to run the systems. A skid-mounted hydraulic-power unit for larger operations is also available, enabling power for multiple actuators simultaneously. — Automation Technology, Inc. (ATI), Houston
