Product description
An automatic air vent releases collected air from the heating circuit continuously, without anyone having to bleed the radiator by hand. Inside the brass body a float follows the water level and opens the venting port while air is present, then closes it the moment water reaches the valve. The F251 vents to the side, which is useful when the space above the valve is blocked by a shelf or a cover.
Key features
- Side venting for restricted space above the valve
- Float operated
- Solid brass, natural colour
- Leak tested on the air tightness rig before shipment
Applications
Installations with limited headroom above the vent.
