Page 2 BV90 fire protection valves Function, volume flow setting Construction and function - The fire protection valve is essentially made up of an inte- grated duct for installation in walls or ceilings (1). - The valve disc (3) is inserted in it. - In the event of fire the release element (4) reacts and closes the valve disc with springs (3). The interlocks (5) are released by unscrewing them. In the pro- cess the inner locking pins are released. Left turn Left turn ⇒ see operating instructions Removing the valve disc (3) Inserting the valve disc (3) Setting the volume flow • In the factory the stroke marks , i.e. the lowest volume flows, are preset. ⇒ Nomograms, page 5 or 6 • Other settings to the stroke marks can be made on site: Stroke marks - To do so, remove the valve disc (3) from the integrated duct (1) by turning it to the left.
