The Polypipe PB00401 is a valve actuator for underfloor heating from Polypipe range. The valve actuators are connected to the underfloor heating manifolds. Polypipe PB00401 valve actuators are designed to open and close supply valves in the system. Valve actuators are normally connected to the underfloor heating manifolds to allow water to flow to specific zones. These valves are electrically operated devices to open and close the manifold valves, allowing water to flow through to an individual room or zone. Each Polypipe compatible replacement actuator is controlled by the room thermostat in the corresponding room or zone.
