Sun Hydraulics FCB-100-01A Flow Control Valve

The Sun Hydraulics FCB-100-01A is a line-mountable or cartridge-style hydraulic flow control valve designed to regulate hydraulic flow while preserving stable system performance under changing pressure, with configuration-dependent pressure compensation. It can function as a flow regulation device suitable for line-mounted manifolds or cartridge installations, and is commonly used in hydraulic manifolds, mobile equipment control systems, industrial presses, and fluid power circuits where precise flow control and load stability are required. Maintenance teams, OEM machine builders, and system integrators rely on the FCB for system tuning, retrofit applications, and replacement of flow control components in industrial hydraulic assemblies. Key specifications include a maximum operating pressure up to 5000 psi (varies by configuration), high-strength steel cartridge construction with aluminum manifold compatibility, and mounting options that are cartridge or Sun T-series cavity‑compatible manifold mounting. The valve supports hydraulic oils (mineral-based and compatible synthetics), with either fixed or adjustable flow control depending on configuration, and variant-specific functionality such as meter-in/meter-out or bypass flow regulation. Common replacements include Sun Hydraulics FCBBLAN flow control cartridge, Parker F600S flow control valve cartridge, and Bosch Rexroth 2FRM-series flow control valves.
