According to the invention, a constant flow valve along with a three way control valve are arranged so as to provide an enhanced shut-off function. During closure of the flow valve, the pressure of the supply fluid is employed in a manner bolstering the valve's spring closure force, thereby resisting any tendency of the valve to open in response to fluid supply pressure surges above the valve's threshold opening level.
