<p>The present invention relates to fluid control and management. In particular, it relates to valves or regulators for controlling a flow of fluid, such as, but not limited to, taps and faucets. We will describe a fluid control valve comprising a valve body having an inlet, for operative connection to a supply of pressurised fluid, and an outlet and defining a fluid flow path therebetween. A first valve is adjustable under the control of a first valve actuator between a first, or closed, position in which flow of fluid through the first valve is prevented and a second, or open, position in which flow of fluid through the first valve is permitted. The valve is characterised in that the fluid control valve further comprises a second valve associated with the inlet or intermediate the inlet and the first valve, wherein the second valve comprises a second valve body and a second valve actuator adapted such that the first valve actuator bears against the second valve actuator in each of said first and second positions to urge the second valve into an open configuration allowing flow of fluid; and further wherein the fluid control valve is arranged such that the first valve actuator is adjustable to a third position in which the first valve actuator is spaced from the second valve actuator by a separation sufficient to allow fluid pressure at the inlet to cause the second valve to close, preventing flow of fluid through the fluid control valve.</p> |
