V&M Hydraulic Valves (V&M Inc.) is a U.S. manufacturer founded in 1948 and based in Sioux Falls, South Dakota. The company builds hydraulic multiplier valves under its Add-A-Valve line, electric-over-hydraulic valves rated from 4 GPM at 3000 psi up to 40 GPM at 4500 psi, and also distributes Ritchie automatic livestock waterers and Flex-Trac traction products. The brand is active: its MV, SV, and DV valve families are still in production and carry a 2-year manufacturer warranty. Northern Hydraulics supplies and cross-references V&M Hydraulic Valves parts and can match replacement and equivalent valves by flow, pressure, and outlet count.
V&M Hydraulic Valves Product Lines & Series
V&M’s catalog centers on multiplier valves that add outlets and functions to an existing tractor or implement hydraulic circuit. The Add-A-Valve family splits a single set of outlets into multiple work circuits without re-plumbing the entire system. Confirmed lines and ratings include:
- Add-A-Valve — standard multiplier, 15 GPM at 3000 PSI.
- Super Add-A-Valve — high-flow multiplier, 45 GPM at 4500 PSI.
- One Way Add-A-Valve — 7 GPM at 3000 PSI.
- SV Series — 6-8 GPM per outlet at 3000 PSI.
- SV Directional Valve — 4-6 GPM per outlet at 3000 PSI.
- DV Series — 15-20 GPM per outlet at 3000 PSI.
- DV Directional Valve — 10-12 GPM per outlet at 3000 PSI.
- Shut Off Block & Pendant Switches — 12 GPM at 3000 PSI.
The MV Series entered manufacturing in 1989 and, alongside the SV and DV families, remains an active offering. V&M added Flex-Trac to its product range in 2000.
Cross-Referencing V&M Hydraulic Valves Parts
When you are matching an existing Add-A-Valve installation or sourcing a replacement multiplier, the deciding specs are GPM rating, working pressure, number of outlets, and whether the circuit is single- or double-acting. V&M’s lines span a broad flow range — from a 7 GPM One Way Add-A-Valve to a 45 GPM Super Add-A-Valve at 4500 PSI — so a correct match depends on the flow per outlet your implement needs, not just the model name stamped on the old housing.
We can cross-reference a V&M part number or a worn unit against an equivalent multiplier valve by flow, pressure, and outlet count, including SV and DV directional configurations. If you have an unlabeled or older multiplier and need to identify the equivalent V&M valve, send us the GPM and PSI you are running and the outlet arrangement. Request a V&M Hydraulic Valves cross-reference quote and we will help match the right valve to your circuit.
