Cartridge Valve

Premium Cartridge Valve

Cartridge valves are compact screw‑in hydraulic valves that control flow, direction, or pressure inside a manifold/block. Their biggest advantage is a small footprint with high performance, which makes them common in loaders, lifts, cranes, plows, and many other hydraulic machines.

Because many cartridge valves look similar, the key is matching the exact function + cavity (size/thread) + coil voltage (if solenoid), so you don’t buy the wrong one.

Common Cartridge Valve Types

Below are the most common types you’ll see on this category page:

1) Solenoid‑Operated Spool Cartridge Valves

• What they do: switch oil flow paths electrically (directional control).
• Where used: boom/lift functions, auxiliary hydraulics, motor control circuits.
• When to pick: you need an on/off valve controlled by a coil (12V/24V).

2) Solenoid‑Operated Poppet Cartridge Valves

• What they do: on/off control with tight shutoff (often lower leakage than spool designs).
• Where used: load holding, isolation, safety shutoff.
• When to pick: you need better sealing or minimal leakage.

3) Check Valves (Cartridge Check)

• What they do: allow flow in one direction only.
• Where used: preventing backflow, protecting circuits, holding pressure.

4) Sequence / Pressure Control Valves

• What they do: open at a set pressure to control the order of operations.
• Where used: stabilizers/outriggers, multi‑function circuits, clamp/hold sequences.

5) Specialty / Machine‑Specific Cartridge Valves

• What they do: replacements made for specific equipment systems (plows, lifts, cranes).
• Where used: Boss RT3 plows, Skyjack lifts, Genie lifts, etc.

4 Common Mistakes You Need to Avoid

• Ordering SV08 when your manifold needs SV10 (cavity mismatch).
• Buying the right valve but the wrong coil voltage (12V vs 24V).
• Mixing up spool vs poppet designs where leakage/sealing matters.
• Replacing a 3‑way valve with a 2‑way valve (function mismatch).
