MalcoEdge Dual-Valve Hi-Flow Y Branch 3/8″ x 3/8″ x 3/8″ (HFYV38)
The MalcoEdge HFYV38 Dual-Valve Hi-Flow Y Branch combines high-flow performance with independent flow control. Each leg of the Y features an integrated ball valve, allowing technicians to isolate hoses, control system flow, and fine-tune evacuation or recovery processes. Designed with a 3/8″ high-flow configuration, this fitting maximizes throughput while maintaining control, making it ideal for complex system setups or staged evacuation workflows.
FAQs
Q1: Why would I use a Hi-Flow Y instead of a manifold?
A1: MalcoEdge Hi-Flow Ys create fewer restrictions and reduce potential leak points compared to traditional manifolds.
Q2: What are the advantages of using a Hi-Flow Y?
A2: Hi-Flow Ys allow multiple hoses to connect to a single port for faster evacuation, recovery, and charging applications. Y connections generally provide improved flow compared to T fittings.
Q3: Are MalcoEdge Hi-Flow Ys vacuum rated?
A3: Yes. MalcoEdge Hi-Flow Ys are vacuum rated to 20 microns.
Q4: What is the maximum working pressure for MalcoEdge Hi-Flow Ys?
A4: MalcoEdge Hi-Flow Ys are rated for 800 psi (55 Bar)
Q5: What is the benefit of the integrated ball valves on the HFYV38?
A5: The integrated ball valves allow each leg of the Y fitting to be independently opened or closed, providing greater control when isolating a line or operating from a single side.
Q6: What do I do if my valve can turn 360 degrees?
A6: The likely cause of this is that the retaining screw on your valve handle has become loose and the handle is able to spin freely while disengaged from the ball valve stem. Fully unscrew the retaining screw with a philips-head screwdriver. Fully remove the ball valve handle from the unit. Inspect the handle and the valve stem to ensure the hex engagement between both the stem and handle have not been stripped or worn. Inspect the ball valve position by looking down the bore of the HYV38. Adjust the ball valve position to the fully open position by turning the valve stem by hand or using the valve handle on the valve stem hex. Re-position the valve handle so that the pointed end of the handle points in the direction of flow for the ball valve and fully seat the knob on the valve. Apply a light amount of blue threadlocker to the handle retaining screw and reinstall the screw. Once assembled, confirm proper orientation of the valve and the knob and open/close operation of the ball valve. The handle should only allow the valve to turn 90-degrees between open and close positions.
