Integral Valve

Abstract

A valve comprising a shoulder, a movable check member having a wall facing the shoulder and a coupling member. The movable check member is adapted to prevent fluid passage through or out of the valve when in contact with the shoulder. The coupling member is adapted to displace the movable check member away from the shoulder responsive to the pressure being applied on the wall exceeding a predetermined threshold. The coupling member is further adapted to retract and maintain the movable check member secured against the shoulder responsive to the fluid flow pressure at the wall dropping below the threshold.

1 . A process of using a plurality of valves in a drip irrigation pipe line configured to house the plurality of valves and one or more drippers deployed therebetween, whereby the plurality of valves divide the pipe line into a plurality of separate segments, each segment is enabled to provide fluid flow via the one or more drippers independently of other segments, each valve of the plurality of valves being configured to allow fluid passage in a single direction responsive to a fluid flow pressure applied thereon exceeding a threshold.
