JG Speedfit JGUFHA(240V)/2 240V UFH Circuit Actuator Valve – Normally Closed 2-Wire Thermal Actuator for Underfloor Heating Manifolds
JG Speedfit JGUFHA(240V)/2 240V UFH Circuit Actuator Valve – Normally Closed 2-Wire Thermal Actuator for Underfloor Heating Manifolds
The JG Speedfit JGUFHA(240V)/2 240V UFH Circuit Actuator Valve (Normally Closed) is a reliable electrothermal actuator designed for John Guest Speedfit underfloor heating manifolds, providing precise individual room temperature control.
Product Description
The JGUFHA(240V)/2 is a 240V normally closed (NC) thermal actuator that opens the flow valve when energised by the room thermostat. It features a fast-acting wax element, first-open function for easy system commissioning, and a clear visual indicator to show power and valve status. The actuator simply screws onto the standard M30 x 1.5 manifold port and connects with just two wires, making it quick and straightforward to install on JG Speedfit underfloor heating systems.
Key Features
- Normally Closed (NC): Opens when powered – standard for most UFH systems.
- First-Open function: Automatically opens during initial filling and commissioning.
- Visual status indicator: Clear window shows power on/off and valve open/closed.
- 2-wire connection: Simple live & neutral wiring (no neutral required in some setups).
- Fast response wax element: Quick open/close times.
- M30 x 1.5 thread: Direct fit for JG Speedfit and most standard UFH manifolds.
- IP54 rated: Protected against dust and water splashes.
- Low power consumption: Approx. 2–3 W when operating.
Technical Specifications
- Model: JGUFHA(240V)/2.
- Voltage: 230–240 V AC, 50/60 Hz.
- Power consumption: 2–3 W (operating).
- Stroke: 4.0 mm.
- Actuating force: 100 N.
- Opening/closing time: Approx. 3–5 minutes.
- Thread: M30 x 1.5.
- Protection rating: IP54.
- Protection class: Class II.
- Cable length: 1 metre (pre-wired 2-core).
Dimensions & Weights
- Height: 55 mm (approx.).
- Diameter: 45 mm.
- Weight: 110 g (including cable).
System & Application Notes
- Specifically designed for JG Speedfit underfloor heating manifolds.
- Compatible with all standard M30 x 1.5 manifold valves.
- Works with JG Speedfit wiring centres and 230V room thermostats.
- Ideal for both new installations and retrofits.
- Professional installation recommended.
- Manufacturer’s warranty: 2 years.
