Gas Valve Actuators
Gas Valve Actuators for Industrial Combustion Systems
A gas valve actuator converts a control signal into the mechanical force needed to open, close, or position a gas valve, turning a manually operated valve into one that can be automated from a burner management system or process controller. Actuator selection depends on the torque the valve requires and the type of control signal available.
Matching an actuator to its valve means confirming required torque, stroke, and fail safe behavior, along with the control signal type the actuator will receive from the burner management system. Correctly paired gas valve actuators support reliable automatic operation and consistent safety shutoff performance. These actuators are suitable for new gas train automation and actuator replacement on existing valves.
Shop Relevant supplies gas valve actuators in pneumatic and electric configurations, sized to match specific gas valve bodies used in combustion gas trains and process gas systems. The category includes actuators for new automated valve assemblies as well as replacement actuators for valves already in service. Ships same day.
Frequently Asked Questions
How do I know what actuator my gas valve needs?
Check the valve manufacturer's specification for required operating torque and stroke, then match those figures along with the available control signal type to an actuator rated for that combination.
What is fail safe behavior on a gas valve actuator?
Fail safe describes how the actuator drives the valve if it loses power or air supply, typically using a spring return to move the valve to its safety position, closed in most fuel gas applications.
Can I replace just the actuator on a gas valve instead of the whole valve?
In most cases yes, provided the replacement actuator is compatible with the valve's mounting interface, stem, and required torque, which keeps replacement cost and downtime lower than swapping the entire valve assembly.
