Thermostatic Towel Rail Radiator Valves are available in an elegant polished chrome plated finish to accompany our range of designer radiators. They are a thermostatically controlled valve and they keep the ambient temperature of the room where they are installed constant at the set value. They are supplied in pairs a thermostatic control valve and a lockshield valve. The lockshield valves are installed on the return branch and are used for the hydraulic balancing of the circuit. Valves are available in straight or angle pattern form with ½” BSP male and ½” Irish size compression connections.
