Overview
The Vickers FDC1-1-033 is a screw-in cartridge valve engineered for flow division and pressure-balanced operation in hydraulic circuits. Manufactured by Eaton (formerly Vickers), this compact, modular unit features ISO 7368 (DIN 24342) compliance and operates reliably at pressures up to 210 bar (3000 psi). The FDC1-1-033 is commonly specified in mobile equipment, industrial machinery, and OEM hydraulic systems where precise flow metering and load sensing are critical.
Key Features
- Pressure-compensated spool design — Maintains consistent flow output regardless of load variations
- ISO 7368 screw-in cartridge construction — Modular design allows integration into existing manifold systems
- Maximum operating pressure: 210 bar (3000 psi)
- Flow control functions — Supports flow division, load-sensing, and pressure-balanced applications
- Compact footprint — Reduces manifold size and system weight
- Durable construction — Proven performance in demanding hydraulic environments
