Our bridge valve is a valve used for ponds and swimming pools. Basically it is a valve whose operation is carried out by a threaded spindle that ascends a bridge that has a threaded upper part. This spindle is joined by a plate and its screws to a disc or plate with a rubber closing gasket that rises and falls as the valve is operated, closing and opening. This plate closes the passage of water in a seat that is horizontal. It has a cast lever or handle (optional) to operate the valve.
The legs on the base of the valve act as claws to place and fix the valve to the surface (soil, cement…).
