Pilot-Operated Check Valves
- Description: Allow fluid flow into an actuator but block reverse flow unless pilot pressure opens the valve.
- Use Case: Suitable for static load holding, such as outrigger cylinders in cranes or boom support in aerial platforms. They prevent drift from slow leaks or hose failures.
- Why Use: Simple, cost-effective, and reliable for static applications. Sun Hydraulics notes low leakage (less than 5 drops/minute) when rigidly mounted.
- Example: HydraForce VBSN-12U-RS or Sun Hydraulics CK** series for compact systems.
