Multi-ported refrigeration valve assembly
View Patent ↗A refrigeration valve having a valve body having an inlet, an outlet, and a flow passage defined therebetween, an expansion valve in the flow passage, a first hand valve between the inlet and the expansion valve, and a second hand valve between the outlet and the expansion valve. The first and second hand valves are provided at a top of the valve body and are movable in a first direction for preventing fluid flow through the flow passage. By providing the first and second hand valves at the top of the valve body rather than at a bottom of the valve body, valve life is increased and the valves are not prevented from operating due to particulate build up in the valves.
1. A refrigeration valve assembly including:
a valve body having an inlet at a first end, an outlet at a second end, a flow passage defined between the inlet and outlet, and a strengthening rib extending between the inlet and the outlet;
a flow control valve between the inlet and the outlet; and
a hand valve between the inlet and the flow control valve for preventing fluid flow from the inlet to the outlet,
wherein the strengthening rib has disposed along a length thereof a plurality of ports extending into the flow passage that individually serve as a drain or a test port.
2. The refrigeration valve assembly according to claim 1 , wherein the flow control valve is an expansion valve in the flow passage for throttling fluid flowing through the flow passage.
3. The refrigeration valve assembly according to claim 1 , wherein the flow control valve is a regulator valve including a plug extending into the flow passage that is movable to regulate the flow of fluid through the flow passage.
4. The refrigeration valve assembly according to claim 1 , further including a hand valve between the outlet and the flow control valve for preventing fluid flow from the outlet to the inlet.
5. The refrigeration valve assembly according to claim 4 , wherein each hand valve is movable in a first direction for preventing fluid flow through the flow passage.
