Abstract:
A combination control and check valve assembly for a wet piping system includes a control valve in the form of a ball valve and a one-way check valve mounted within the flow pathway of the ball valve. A valve actuation assembly is mounted to the valve assembly to selectively rotate the ball valve between the open and closed positions thereof. The valve actuation assembly is mounted to a first side of the valve assembly and rotationally fixed to the ball, whereby rotation of the valve actuation assembly rotates the ball between the open and closed positions. A side opening is formed in a second side of the valve assembly that is angularly spaced from the first side. The side opening is positioned to align with the fluid flow pathway of the ball valve in the closed position thereof to provide access to the check valve.

Claim (Index 1):
A combination control and check valve assembly for a wet piping system, the valve assembly comprising:\n a valve body defining an inlet of the valve assembly, an outlet and a valve body fluid flow pathway therebetween; a ball valve positioned within the valve body, the ball valve comprising a rotatable ball, an upstream sealing seat ring positioned on an inlet side of the ball and a downstream sealing seat ring positioned on a downstream side of the ball, the ball having an inlet opening, an outlet opening and a ball fluid flow pathway therebetween, and the upstream and downstream seat rings being configured to substantially seal off fluid flow between an upstream side and a downstream side of the ball except for travel through the ball fluid flow pathway; a valve actuation assembly configured to selectively rotate the ball between an open position, fluidly connecting the ball fluid flow pathway with the valve body fluid flow pathway to permit fluid flow from the inlet to the outlet of the valve body through the ball, and a closed position, substantially fluidly disconnecting the ball fluid flow path from the valve body fluid flow path to substantially prevent fluid flow from the inlet to the outlet of the valve body, the valve actuation assembly including a stem extending from outside the valve body, through a first side thereof and into rotationally fixed attachment with the ball, whereby rotation of the stem rotates the ball between the open and closed positions thereof irrespective of a pressure differential across the ball; a one-way check valve mounted within the ball, the check valve being movable according to a pressure differential across the check valve between a closed position, blocking fluid flow through the ball fluid flow pathway, and an open position, permitting fluid flow through the ball fluid flow pathway in a direction from the inlet side to the outlet side thereof; a side opening formed in a second side of the valve body that is angularly spaced approximately 90\u00b0 from the first side of the valve body, the side opening being positioned to align with and access the ball fluid flow pathway in the closed position of the ball, and the side opening being dimensioned to permit passage of the check valve therethrough; and a side cover removably closing the side opening.
