Product Code ESAVBCV
Automatic Air Vent 3/8" and 1/2"
The ESi Controls automatic air vents are designed for heating systems and other closed circuit hot water systems which require the efficient, automatic removal of air when a system is filling with water. The ESAVBCV allows quick and easy removal of trapped air from sealed heating systems without draining down the system and reduces, and often eliminates, the need for bleeding.
The ESAVBCV features a vacuum break on the base of the valve to prevent an air lock forming and to encourage air to be released from water. The ESAVBCV can be fitted anywhere in the positive pressure side of the system where air is likely to be trapped, although it should be installed in an accessible and visible area to ensure it can be serviced easily.
