Pilot-Operated Check Valves Professional Supplier In China
Pilot-Operated Check Valves
- Operation: Block reverse flow by default but can be opened remotely using a pilot pressure signal.
- Critical Feature: Controlled reverse flow on demand, enabling dynamic system adjustments.
- Typical Use: Applications requiring precise control, such as locking hydraulic cylinders or emergency pressure release.
Applications
- Hydraulic Cylinders: Ideal for equipment requiring position holding (e.g., construction machinery, industrial presses).
- Safety Systems: Enables emergency pressure relief in critical circuits.
- Energy Recovery: Redirects fluid to optimize energy use in complex hydraulic systems.

250 bar (3,600 Psi), 25 L/min, Ratio 3:1
250 bar (3,600 Psi), 30 L/min, Ratio 4:1
Unlock backflow only when needed (e.g., for system maintenance or emergency releases). Eliminates the need for manual intervention or system disassembly.
207 bar (3,000 Psi), 15 L/min, Ratio 3:1
240 bar (3,500 Psi), 30 L/min, Ratio 3:1
Securely locks hydraulic cylinders under load (prevents drift in cranes, presses, or lifts). Maintains position even during pressure drops.
Yes, but it is recommended for systems requiring controlled reverse flow. For basic one-way flow, standard valves are more cost-effective.
The valve defaults to its closed state, blocking reverse flow to ensure system safety.
Check for insufficient pilot pressure, clogged pilot lines, or worn components.
