Thermoelectric actuator for underfloor heating that promises dependable valve actuation. Installers and homeowners who want quiet, low-maintenance control gain reassurance with WENGART Thermoelectric Actuator WG2208. Is paraffin-driven actuation with spring-return safety the right choice for your heating system?
⚡ At a Glance
- • Actuation Performance: 110N thrust, 3mm stroke, opening time 3-5 minutes for measured valve movement
- • Best for: Underfloor heating systems requiring quiet, maintenance-free valve control
- • Not ideal for: Applications needing instant valve movement or very large valve travel
Electrothermal actuation uses paraffin propulsion and a PTC heating drive with a spring-return mechanism. Standard M30x1.5mm thread and two-wire connection allow straightforward installation on compatible valve bodies.
Precise valve movement - with 110N thrust and 3mm stroke
Thrust of 110N and a 3mm stroke generate the mechanical force and travel required to open or close compatible valves, with an opening time of about 3-5 minutes. Thermal expansion of the paraffin element, driven by a PTC heater, produces the linear motion.
Reliable, measured valve operation ensures thermostatic signals translate into consistent flow control. Suitable where gradual, controlled valve actuation is preferred over abrupt movement.
Low-maintenance, quiet operation - thanks to paraffin propulsion and no mechanical transmission
Paraffin expansion and contraction provide the driving force without gears or complex mechanical linkages, while the PTC heating element regulates temperature for stable cycles. The design minimises moving parts, reducing wear and noise.
Long service life and minimal upkeep reduce running headaches for homeowners and maintenance teams. Quiet operation keeps living spaces and hotel rooms undisturbed.
Safe fail‑back and easy installation - with spring return and M30x1.5 interface
A built-in spring return restores the valve to its original position when power is lost, providing a fail-safe state. A standard M30x1.5mm threaded interface accepts common valve bodies and requires only two wires for connection.
Fail-safe behaviour protects systems during outages while installers benefit from a fast, compatible fit on standard valves. Visible open/closed indication makes status checks immediate and straightforward.
