SAE Cartridge Valves
- Pressure relief valves These valves are used as pressure limiting devices to protect hydraulic systems.
- Pressure reducing valves Pressure reducing valves are pressure limiting devices that limit pressure in one portion of a circuit while leaving system pressure unaffected.
- Sequence valves As the name implies, sequence valves control a sequence of operations. Sequence valves usually use a pressure signal to shift a spool, thereby opening or closing a flow path at a pre-set pressure.
- Check valves Check valves allow free flow in one direction and block flow in the opposite direction.
- Pilot operated check valves Pilot operated check valves are used to prevent a load from dropping in case of hose or tube failure or from drifting caused by directional control valve spool leakage.
- Needle valves Needle valves provide adjustable, non-compensated flow control. They are available with standard or fine adjust, and with a variety of knob adjusting options.
- Flow regulator pressure compensated valves Pressure compensated flow control valves are used to limit or regulate flow.
- Counterbalance valves Counterbalance valves are used to control the motion of a load in the following ways: - prevent a load from dropping in case of hose or tube failure or from drifting caused by directional control valve spool leakage. - provide smooth, modulated motion when the load is in a lowering or run‑away mode or when the directional control valve is suddenly closed.
- Directional solenoid valves Solenoid valves are electrically-operated, on-off poppet or spool-type valves for load holding, blocking, or directional control applications.
