JG Speedfit UFH Underfloor Heating Manifold Isolating Valve SPUFH11

Automatically shutting return circuits when not in use, the temperature-operated JG Speedfit UFH Underfloor Heating Manifold Isolating Valve controls water flow, reduces heat loss and maintains system efficiency 

Designed for installation on the return side of JG underfloor heating manifolds, the JG Speedfit UFH Underfloor Heating Manifold Isolating Valve is a temperature-operated device that regulates flow through the return circuit. The valve remains closed at low temperatures and automatically controls individual circuits by responding to the changes in water temperature within the system. As the heated water starts to circulate, the internal thermostatic element senses the rising temperature and gradually opens the valve to allow return flow. When heat demand stops and the system begins to cool, the valve closes again, isolating the circuit and prevents unwanted circulation of water.

Features

• Temperature-operated valve – Controlling return flow by automatically responding to system water temperature changes
• Return circuit installation – Designed specifically for fitting on the manifold return rail
• Thermostatic control element – Uses an internal temperature-sensitive device to regulate valve opening and closing
• Automatic circuit isolation – When system temperature drops or heat demand stop, the valve closes
• Progressive opening action – When return water temperature increases, for controlled flow, the valve gradually opens
• Reduces unwanted circulation – Prevent residual flow through inactive loops, improving system efficiency
• Energy efficiency support – Reduces standby heat loss within the underfloor heating system
• Compatible with JG Speedfit manifolds – Allows for seamless integration with JG UFH underfloor heating systems
