1. An arrangement for testing and draining a fire suppression sprinkler system, comprising:
- conduit means for supplying a fire suppression fluid to a plurality of sprinklers;
means for sensing a flow of said fire suppression fluid in said conduit means;
a valve having a housing with an inlet and a first outlet, the inlet and the first outlet being provided on opposite ends of the housing with a ball valve member being provided in the housing between the inlet and the first outlet;
a valve seal provided between the ball valve member and said first outlet for sealingly engaging the outer surface of said ball valve member;
a valve seat provided between the ball valve member and the inlet, said valve seat permitting continuous communication between the inlet and the interior of the housing;
a pressure relief valve having an inlet in communication with the interior of said housing;
said ball valve member having a first passageway which permits flow from the inlet to the first outlet at a first flow rate when the first passageway is aligned with the inlet and the first outlet, said first flow rate enabling said arrangement to be drained, said ball valve member having a second passageway which permits flow from the inlet to the first outlet at a second flow rate which is less than the first flow rate when the second passageway is aligned with the inlet and the first outlet, said second flow rate enabling the means for sensing a flow of said fire suppression fluid in said conduit means to be tested; and
, means for moving said ball valve member within said housing.

Abstract
A valve and valve arrangement for a fire suppression system includes a valve having an inlet and an outlet provided on opposite ends of the valve housing with a pressure relief valve in communication with the interior of the housing. A gap in a seat for the valve member provides communication with the inlet of the valve. In another embodiment, a valve has a disk provided in a passageway through the valve member to restrict the flow through the valve to a predetermined rate which is less than the fully opened flow rate through the valve.
