ABSTRACT:
A valve and an arrangement for testing and draining a fire suppression water sprinkler system includes a valve which has a valve member with first, second and third ports. The selective rotation of the valve member interrupts a flow of water through the valve and permits a flow at one or two preselected flow rates. The valve is provided with a pressure relief valve with an outlet of the pressure relief valve preferably communicating with the outlet of the valve.
