Válvula hidráulica en línea de retención de carga con contrapeso y cuerpo para elevaciones de alta resistencia, 4 puertos, 15 GPM a 3000 PSI, relación de pilotaje 3:1, cavidad T-11A, puertos con junta tórica SAE , Seals de Viton, amplio rango de funcionamiento de 1015 a 4060 PSI

Single inline hydraulic counterbalance valve for lifts
✔️ 4-port inline counterbalance valve, 15.9 GPM @ 300 psi, 3:1 pilot

This inline hydraulic counterbalance load holding valve is designed to keep heavy actuators in place, preventing unintended movement if pressure is lost. It's commonly used on heavy-duty lifts, hoists, cranes, and hydraulic presses to improve safety and control.

✅ Operating pressure: 1015 to 4060 psi (70 to 280 bar).
✅ 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
