Eliminating Methane Venting with Electric Actuator Technology

August 4, 2026

Electro-hydraulic actuator technology eliminates venting emissions while delivering precise process control and improved asset reliability.

The Challenge

Remote well pads and compressor stations often rely on pneumatic devices that continuously vent methane as part of normal operation. This creates several operational and environmental challenges:

Methane venting contributes to greenhouse gas emissions.
Emissions reporting requirements create ongoing compliance and administrative burdens.
Pneumatic control devices can make it difficult to achieve corporate zero-emission site objectives.
Multiple devices are often required to provide both control and emergency shutdown (ESD) functions, increasing system complexity.
Remote assets require reliable performance with limited maintenance intervention.

The Solution

Spartan Controls implemented electro-hydraulic actuator technology to replace venting pneumatic devices.

The self-contained actuator system uses hydraulic fluid pressure to create stored energy through gas-charged accumulators or compressed actuator springs, providing failsafe positioning without the need for external backup power systems.

Key solution features include:

Electro-hydraulic actuator with integrated reservoir, control electronics, and actuator assembly.
High-speed, high-accuracy process control.
Non-intrusive commissioning and configuration through local user interface and Bluetooth connectivity.
Advanced diagnostics when paired with DCMlink.
Real-time operational visibility through HART communications.
Continuous modulating duty with low power consumption.
Integrated control and ESD functionality within a single device.
No separate UPS, battery backup, or supercapacitor systems required.
