Abstract
A wet piping system modular valve assembly includes a single piece valve body with a check valve within the valve body. The check valve is movable between a closed position and an open position according to a pressure differential across the check valve. A drain valve is removably mounted to the valve body and fluidly connected with the valve body downstream of the check valve. A mechanically independent flow detection switch is removably mounted to the valve body and fluidly connected with the valve body upstream of the drain valve.
Claims14
A wet piping system modular valve assembly comprising:
- a valve body having an inlet, an outlet and a fluid pathway therebetween;
- a combination check and control valve comprising:
- an endless valve seat within the valve body and a clapper disk removably and pivotably mounted within the valve body, the clapper disk being movable between a closed position and an open position according to a pressure differential across the clapper disk, the clapper disk being in sealed engagement with the endless valve seat in the closed position and the clapper disk being spaced away from the endless valve seat in the open position;
- and
- a selectively rotatable actuator arm rotatably supported by the valve body, the actuator arm being rotatable between a first position, permitting fluid to move the clapper disk into the open position and flow through the valve seat according to the pressure differential across the clapper disk, and a second position, preventing fluid from moving the clapper disk into the open position irrespective of the pressure differential across the clapper disk;
- a drain valve removably mounted to the valve body and fluidly connected with the fluid pathway downstream of the combination check and control valve;
- and
- a flow detection switch removably mounted to the valve body and fluidly connected with the fluid pathway upstream of the drain valve,
- wherein the valve body includes a pair of first ports extending through, and being generally oppositely disposed about, a sidewall of the valve body, and being in fluid communication with the interior of the valve body, the drain valve being removably coupled to either one of the pair of first ports.

- a flow detection switch removably mounted to the valve body and fluidly connected with the fluid pathway upstream of the drain valve;
- and
- a pressure relief valve coupled to the valve body,
- wherein the drain valve and the pressure relief valve are combined into a single drain and pressure relief module.
