In the unlocked position, the valve permits varying fluid pressure in the conduit, whilst in the locked position an excess pressure can be maintained in the conduit. The valve comprises a housing with inlet (13) and outlet (14) channels and is connected to a pressure fluid conduit (5). It has a valve chamber inside which is a movable valve unit (9) with one or more connecting apertures (8.2). - These apertures connect the inlet and outlet channels (13,14) when the valve is in the unlocked position. They connect the inlet and outlet channels via the stop pressure channel (15) when the valve is locked. |
