Dual-plate check valve BB 2...
Undo threaded bolts, turn semicircular plates to the
left.
Take out semicircular plates, springs and support
plates.
Remove support plates, cover springs and withdraw
hinge pins.
Danger
Note that springs are preloaded, which means that they can jump out of the plate body
when the valve is being installed or removed.
This presents the risk of injuries to hands, arms and face.
