Worcester Air Vent Valve 87161064450

Air Vent Valve Worcester Fits a number of Worcester Boilers

The Worcester Bosch air vent is for use in the pump section of Worcester Bosch's Greenstar, Greenstar 8000 Life, Greenstar 8000 Style and Greenstar ErP boiler range. In the central heating safety device, an air vent releases built up air. As water flows through, a float closes or opens the vent based on the water level. The float is forced to the top of the system when it is full, blocking the vent until the water level drops.

• Fits a number of Worcester boilers
