A valve and an arrangement for a fire suppression water sprinkler system includes a valve which has an inlet and an outlet with a restricted orifice to limit the flow through the valve to correspond to the flow through a single sprinkler head. The valve has a biasing member so that the valve opens when the pressure in the inlet exceeds a predetermined pressure and the valve may be opened manually to test the system or to drain the system.
