The Sun Hydraulics FXCA-X1N is a fixed-orifice, pressure-compensated flow control valve. It is designed to maintain a constant flow rate regardless of pressure variations in the hydraulic circuit.
Technical Specifications According to official documentation from Sun Hydraulics, the FXCA model features the following core specifications for its Series 1 frame size:
Cavity: T-13A. Capacity: Standard models in this series handle up to 6 gpm (23 L/min). Maximum Operating Pressure: 5000 psi (350 bar). Installation Torque: 30 - 35 lbf ft (41 - 47 Nm). Valve Hex Size: 7/8 in. (22.2 mm). Flow Accuracy: Factory-set flow ratings are typically within +/- 10% of the requested setting.
Configuration Details The specific model code FXCA-X1N breaks down as follows based on Sun Hydraulics configuration guides:
Control (X): Not adjustable (fixed orifice). Setting Range (1): Often refers to a specific flow rate or orifice range; however, in standard FXCA nomenclature, specific flow rates are typically assigned letter codes (e.g., "A" for .1-6 gpm). In related models like the FXCC, "1" or similar numeric codes designate specific pre-set flow rates. Seal Material (N): Buna-N seals, which are standard for most petroleum-based hydraulic fluids.
Key Performance Features Viscosity Stability: The sharp-edged orifice design is engineered to minimize flow variations caused by changes in fluid viscosity. Floating Construction: Utilizes Sun's "floating style" design to prevent internal parts from binding due to excessive installation torque or machining variations in the cavity. Interchangeability: All 2-port flow control cartridges within the same frame size are physically and functionally interchangeable.
