Product Description

Fire hydrant

* Manual control type
* Normally open, the valve will close after the break-down of fuse when the temperature reaches high degrees , stop the smoke to extend along the air duct.
* It can work as a volume control damper when open to adjust the air volume. The blade is reset by manually.
