PS Automation

Electric linear actuators for simple control operations, up to 30 kN.

Use it whenUse it as the standard linear electric actuator on globe and control valves where you need straightforward positioning and do not need on-board smart control. This is the bulk of the linear range and the widest force span.

Linear actuators up to 25 kN with the patented PS-AMS smart actuator electronics, for simple and advanced control operations.

Use it whenUse it when you want the control intelligence inside the actuator -- setup, diagnostics and advanced control without an external positioner or controller. Choose this over the plain PSL when the valve is on a modulating loop you will need to tune or monitor.

Linear actuators up to 2 kN with a mechanical failsafe function (PSF) or a manual override (PSF-M).

Use it whenUse it on smaller linear valves that must drive to a safe position when power is lost, or that an operator must be able to move by hand. If the process cannot tolerate a valve holding last position on a power failure, this is the family -- not an accessory on a PSL.

Explosion-proof versions of the PSF linear actuator, with failsafe function or manual override.

Use it whenUse it when a small linear valve with a failsafe or manual override sits in a classified area. Confirm the specific approval and zone against the datasheet before ordering.

Electric 90 degree quarter-turn actuators for simple control operations, up to 3000 Nm.

Use it whenUse it as the standard electric quarter-turn actuator for ball and butterfly valves, right up to large sizes. Start here for on-off and basic control duty.

Quarter-turn actuators up to 3000 Nm with the PS-AMS smart actuator electronics, for simple and advanced control operations.

Use it whenUse it when the quarter-turn valve is on a modulating loop and you want the control, configuration and diagnostics built into the actuator instead of adding an external positioner.

An efficient quarter-turn actuator up to 150 Nm.

Use it whenUse it on small and mid-size ball and butterfly valves where the full PSQ is more actuator than the valve needs and cost and size matter.

Robust industrial actuators for the low power range, up to 50 Nm.

Use it whenUse it on the smallest quarter-turn valves and dampers where you want an industrial-grade unit rather than a light commercial one, but the torque requirement is genuinely small.

Intelligent quarter-turn actuators for simple and advanced control operations up to 80 Nm, with manual override on the -M version.

Use it whenUse it on small quarter-turn valves where you want intelligent control in a compact unit, and specify the -M version when an operator must be able to move the valve by hand.

Explosion-proof intelligent quarter-turn actuators up to 80 Nm, with manual override on the -M version.

Use it whenUse it for small classified-area quarter-turn valves. Verify the approval and zone on the datasheet.

An intelligent explosion-proof quarter-turn actuator in a new compact housing, with a Wi-Fi access point for wireless parameterisation and operation.

Use it whenUse it in a classified area where opening an enclosure to configure an actuator is a permit-and-hot-work problem. Being able to set the actuator up over Wi-Fi without breaking the explosion-proof seal is the specific reason to pick this one, and it is the most interesting product in the line.

Accessory components specific to the PS-AMS smart actuator platform.

Use it whenUse it when adding to or servicing a PS-AMS actuator -- match the accessory to the platform, since the smart and standard ranges are not interchangeable.

General-purpose accessory components for the non-smart actuator range.

Use it whenUse it for the PSL, PSQ and PSF families. Confirm the part against the actuator series before ordering.
