Patent ID: 7945989

Claim:
A valve assembly, comprising: a flow valve chamber having a first inlet port and a first outlet port; an actuator slideably positioned within the flow valve chamber and adapted to be moved from a first actuator position to a second actuator position by fluid pressure from a fluid comprising at least a first liquid entering the valve chamber through the first inlet port; a priming assembly adapted to vent air from the flow valve chamber, the priming assembly comprising a float chamber, a float movably positioned within the float chamber, a vent to atmosphere, and a priming port in fluid communication with the flow valve chamber; wherein, the flow valve chamber further comprises a second inlet port and a second outlet port; and, a secondary liquid valve is operably coupled to the actuator, the secondary liquid valve being fluidly positioned between the second inlet port and the second outlet port and adapted to be moved between a first valve position in which the secondary liquid valve prevents a second liquid from passing from the second inlet port to the second outlet port, and a second valve position in which the secondary liquid valve allows the second liquid to pass from the second inlet port to the second outlet port.
