✅ Flow rate: 15.9 GPM (60 LPM) at 300 psi pressure drop.
✅ Pilot ratio: 3:1.
✅ Check valve spring opening: 25 psi (1.7 bar).
✅ Seals: Viton.
✅ Temperature range: -22 to 230 F (-30 to 110 C).
✅ Ports: SAE -8 O-ring Boss; 3/4-16 thread, nominal 1/2".
✅ Leakage: 5 drops/min at 3000 psi (210 bar).
✅ Filtration: 25 micron or better.
✅ Cavity: T-11A.
✅ Application: Holds load in lifting systems for safety in power loss.

💡 What is an inline hydraulic counterbalance valve used for in lifting systems?

This handy device helps prevent unexpected actuator movement by balancing load against system pressure.

- Load holding maintains actuator position under changing pressure - Pilot ratio 3:1 provides predictable response to backpressure - Viton seals and 25 micron filtration help durability and oil cleanliness
