Thermal Actuator 920080PL
The 920080PL Modulating Thermal Actuator is a Normally Closed electrothermal valve actuator with 0-10V DC proportional control, positioning the valve continuously in response to a control signal rather than simply switching it on or off. Built with a heat-resistant glass-fiber reinforced PA66+30%GF housing, it produces a linear force of 120±10N and a stroke of ≥4mm from a 24V supply while drawing only 2W of power.
Because valve position follows the 0-10V signal, the 920080PL delivers precise, modulating flow control that suits building automation systems and modern climate controllers. It supports selectable operating modes, including an energy saving and comfort mode, a heating mode, and an off state, and uses a convenient plug-in cable connection for quick wiring. With an M30x1.5mm adapter, IP54 protection, and compliance with the EN 60730 standard, it combines accurate proportional actuation with the quiet, wear-free operation expected of a thermal actuator.
Key Benefits
- 0-10V DC proportional control – Valve position tracks the control signal for smooth, modulating flow regulation instead of simple on/off switching, giving finer temperature accuracy
- Selectable control modes – Supports energy saving and comfort mode, heating mode, and an off state to match different operating needs
- Linear movement – Direct linear actuation delivers predictable, proportional travel across the stroke range
- Plug-in cable connection – A plug-in wiring method speeds installation and servicing compared with fixed terminal connections
- Normally Closed fail-safe action – The valve closes when de-energized, stopping flow to the circuit as a safe default
- Strong 120±10N force – Provides firm, reliable actuation for demanding valve assemblies
- Low power draw – Consumes just 2W with a maximum starting current of 300mA, easing the load on the control power supply
- IP54 protection grade – Dust and splash protection suits manifold cabinets and utility-room installations
- EN 60730 compliant – Meets the international standard for automatic electrical controls for household and similar use
- OEM and ODM customization available – Force, cable, adapter thread, and housing can be adapted to specific product requirements

Application & Use Cases
- Modulating underfloor heating and cooling – Proportional 0-10V control adjusts flow continuously for tighter room temperature accuracy than on/off actuators
- Fan coil units – Regulates water flow proportionally in commercial HVAC fan coils for smooth capacity control
- Chilled and heated ceilings and beams – Suits radiant systems that rely on fine, continuous valve modulation
- Building automation systems – Integrates with BMS and controllers that provide a 0-10V analog output for zone-level flow control
- Precision climate zones – Applied where comfort and energy efficiency depend on accurate, proportional valve positioning
Installation Notes
- Mount the actuator on a compatible valve using the M30x1.5mm adapter, confirming the valve thread beforehand
- Provide a stable 24V supply and connect the 0-10V DC control signal from the controller or BMS according to the wiring diagram
- Use the plug-in connection with the supplied 3×0.5mm² 800mm cable, observing correct conductor assignment
- Ensure the power supply can handle the maximum starting current of 300mA per actuator, particularly when several units start together
- Select the appropriate control mode (energy saving and comfort, heating, or off) for the installation
- Because the actuator is Normally Closed, the valve stays shut at a 0V signal or when de-energized. Confirm this suits the control logic
- Allow the 3 to 5 minute response time. Movement is proportional and gradual by design, not instantaneous
- Observe the IP54 rating and keep the unit within the 0°C to 60°C working range, installed upright on the valve
- For OEM integration, confirm three key parameters in writing before finalizing the order: force, control signal, and adapter thread
Frequently Asked Questions
How is a 0-10V modulating actuator different from an on/off actuator?
An on/off actuator has only two states, fully open or fully closed. The 920080PL instead positions the valve in proportion to a 0-10V control signal, so intermediate voltages hold the valve partly open. This continuous modulation gives finer control of flow and temperature, which improves comfort and can reduce energy use in systems designed for proportional control.
What are the control modes for?
The actuator supports selectable operating modes, including an energy saving and comfort mode, a heating mode, and an off state. These let the installation match its behavior to the season and the comfort or efficiency priorities of the space. Refer to the user manual for how each mode is selected and applied.
What does the plug-in wire connection mean?
Rather than fixing individual wires to terminals, the 920080PL uses a plug-in cable connection. This makes installation and servicing faster and reduces the chance of wiring errors, which is useful on manifolds with several actuators.
What controller do I need to drive it?
You need a thermostat, controller, or building automation system that provides a 0-10V DC analog output for each zone, along with a 24V supply for the actuator. If you are planning a system, our team can advise on compatibility.
Which valves is the 920080PL compatible with?
The actuator connects through an M30x1.5mm adapter, which fits the majority of underfloor heating manifold valves and common zone valve bodies. Confirm that your valve uses the M30x1.5 thread before ordering.
