ABSTRACT:
A mains pressure valve including a main chamber having an inlet chamber for fluid and an outlet for fluid, a non-return valve located downstream of the outlet and adapted to provide resistance to fluid flowing therethrough, a piston located in the main chamber which is movable into and out of sealing engagement with the outlet of the main chamber and which defines above it an upper portion of the main chamber and having an internal passageway which communicates between the upper portion of the main chamber and the inlet, a port in the upper portion which permits fluid to flow therethrough, and actuation control associated with the port to regulate the flow of fluid through the port. Upon actuation, fluid in the upper portion drains through the port, allowing the piston to rise and mains pressure fluid passes from the inlet chamber through main chamber and out discharge chamber. The non-return valve provides some resistance to the passage of fluid to reduce the vacuum force created by the passage of fluid at mains pressure. Fluid bleeds via the flow valves into the upper portion and, when the port is closed, piston closes the valve after a predetermined period.
