Ball check valve with loose flange

The ball check valve is provided with one loose flange which considerably facilitates the exchange of existing valves. In case of new constructions the manhole can be built smaller, since a dismantling piece is not required.

The hinged cover can be opened and closed easily. Therefore bolts, nuts and washers don't have to be loosened thus preventing their falling into the shaft.

For draining or flushing the ball check valve the body is provided with a 1/2" female thread outlet of stainless steel.
