Excess flow valve

摘要

The pipe break valve is for closure of a pressure medium conduit in the event of damage and comprises a housing (1) with an inner chamber (2) and a valve plate (4) spring (3)-loaded in an o pen position for closure of the inner chamber. The valve plate in a closure position locates with a peripheral edge on a correspondingly formed sealing surface of the housing. A shaft (5) at one end has a head (6) for location of the spring and at the other end at least one securing component activating the outside of the valve plate. In the inner chamber is an insert body (9), which has flow through passages (8) for the pressure medium. The valve plate and the insert body are centrally penetrated by the shaft.
