The Sun Hydraulics FCDBNAV (Material Number: FCDBNAV) is a fixed-orifice, pressure-compensated flow control valve with a reverse flow check feature, designed for precise flow regulation in meter-in or meter-out applications where there may be significant pressure fluctuations. It incorporates an integral high-capacity check valve that provides unrestricted flow from port 2 to port 1. The flow setting of this valve is specified by the user and calibrated at the factory, ensuring accuracy within 10% of the requested setting. This model is part of Sun's 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity for a given frame size, although cartridge extension dimensions from the mounting surface may vary. The sharp-edged orifice design minimizes variations due to changes in fluid viscosity, while the tunable control option allows for a \u00b125% variation from the nominal factory preset flow by adjusting clockwise to increase flow. This model features corrosion-resistant options identified by suffixes AP or LH for external stainless steel components or zinc-nickel plating, respectively. The Sun floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. With a capacity of 12 gpm (45 L/min) and maximum operating pressure up to 5000 psi (350 bar), this valve is suitable for high-pressure applications. It fits into cavity T-5A with a series number of 2 and requires an installation torque between 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and the locknut requires a torque between 80-90 lbf in (9-10 Nm). The model weighs approximately .50 lb (0.25 kg).

Fixed-orifice, pressure-compensated flow controls with reverse-flow check provide precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. The flow setting is specified by the user and is set at the factory.
- Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
