1 to 30 kN depending on model
Stroke lengths from 50 to 95 mm
Optional Positioner
Manual Override
Linear actuation, precisely configured to your valve specifications
PSL is PS Automation's standard series of linear electric actuators. It is designed for globe valves, control valves, and other linear-stem mechanisms where thrust, stroke, and mounting interfaces align. Modulating control requires a compatible positioner. Advanced PS-AMS diagnostic and configuration functions are available in a separate product line.
Optimized Operating Force
The selection depends on the seating torque and the dynamic load across the full stroke.
Effective Stroke
Models accommodate maximum stroke lengths of 50, 65, or 95 mm, depending on the part number.
Customized Actuation Options
PSAP positioner, position feedback, and additional limit switches are optional features to be selected.
Manual Override
The manual override allows the actuator to be operated in accordance with model-specific procedures.

Voltage, frequency, and duty cycle ratings depend on the part number ordered.
Select the right PSL to seamlessly integrate with your valve
A replacement is never just about matching the torque or thrust rating on a nameplate. We thoroughly inspect the valve, stem connection, and actuator to engineer the right configuration, then verify immediate availability from our local inventory.
Mechanical Specifications
Operating Load
PSL technical datasheets specify an average allowable thrust over the full stroke of 50% of the maximum force. Be sure to also verify the seating thrust.
Stroke and Speed
Record the effective stroke in mm and the desired operating speed in mm/s. Operating speed varies based on motor selection, voltage, and frequency.
Valve Interface
Inspect the yoke rods, stem coupling, threading, overall dimensions, and manual override clearance.
Electrical Specifications and Service
Orders and Returns
Please specify three-point floating or modulating control. Note that the positioner and position transmitter are separate components.
Power Supply and Frequency
Please provide the voltage, AC or DC, frequency, and phase count. A 50 Hz specification does not automatically reflect performance at 60 Hz.
Service and Environment
Verify the duty cycle, operating cycles, ambient temperature, and IP rating of the part number. Media temperature primarily impacts the valve and its mounting assembly.
Start with a photo of the nameplate and any data you have on hand. Our team will work with you to clarify missing details, identify practical options, and confirm the lead time for the selected PSL.
Control and Signalling
Select only the options required for your control loop. Availability depends on the model and its electrical configuration.
Optional PSAP positioner
The analogue positioner requires a compatible potentiometer. The signal range and break detection depend on the PSAP version.
Potentiometer or PSPT Transmitter
Resistive feedback and active feedback are not interchangeable. Please specify the signal input required by your PLC.
Contact & Protection
Additional limit switches, an anti-condensation heater, or IP67 protection are available depending on the specific part number. Please note that spring-return functionality is not available on the standard PSL series.
