EIM G-Series Pneumatic Direct Gas Gear Motor
The EIM G-Gas actuator is a high pressure direct gas driven pneumatic actuator. It is designed to provide fast stroking speeds for large quarter turn and linear gate valves on gas pipelines. Ideal for applications where there is no electricity and high pressure is readily available.
The EIM™ G-Series Pneumatic Direct Gas Gear Motor, manufactured by Emerson, is a high-torque, heavy-duty actuator drive solution engineered for reliable valve automation in demanding oil and gas environments. Designed for direct gas operation, this gear motor uses pipeline gas pressure to deliver powerful rotary motion for actuating quarter-turn or multi-turn valves — without requiring an external power source.
Built for rugged field service, the EIM G-Series features a precision-engineered gear train and robust pneumatic drive mechanism that ensures smooth, efficient torque transmission even under fluctuating gas conditions. Its modular design allows for easy configuration, maintenance, and integration with a wide range of control systems, including fail-safe and remote automation setups.
The direct gas operation eliminates the need for separate pneumatic or hydraulic supply systems, making it ideal for remote wellheads, pipelines, and compressor stations where power availability is limited. Constructed with corrosion-resistant materials, it is built to perform in harsh onshore and offshore environments.
Engineered to meet the stringent requirements of the oil, gas, and petrochemical industries, the EIM G-Series Pneumatic Direct Gas Gear Motor provides unmatched reliability, long service life, and precise control in mission-critical applications.
