Abstract: Provided is a fluid flow valve including a housing including a fluid inlet port, and a fluid outlet port including an outlet aperture and a valve seating bounding the outlet aperture; a sealing-member configured to be biased, under fluid pressure within the housing, against the valve seating so as to seal the outlet aperture; a sealing-member displacing mechanism secured to the sealing-member so that displacement of the displacing mechanism in a first sense detaches the sealing-member from the valve seating so as to open the outlet aperture, while displacement of the displacing mechanism in an opposite sense allows for the sealing-member to become sealingly biased against the valve seating; and a sealing-member opening mechanism configured for displacing the sealing-member against the biasing effect of the displacing mechanism so as to discharge the fluid flow valve.
