The Sun Hydraulics FXDA8BN (FXDA8BN) is a fixed-orifice, pressure-compensated flow control valve designed with an integral pilot control cavity, compatible with any T8A pilot control cartridge. This valve is ideal for precise flow regulation in meter-in or meter-out applications, especially where there are significant pressure fluctuations. The flow setting is determined by the user and calibrated at the factory, ensuring accuracy within 10% of the specified value. This model features a sharp-edged orifice design that minimizes flow variations due to changes in viscosity and employs Sun's floating style construction to prevent internal binding from excessive torque or machining variations. The FXDA8BN supports a capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It requires installation torque between 45 to 50 lbf ft (61 to 68 Nm) and has a valve hex size of 1-1/8 inches (28.6 mm). The device weighs approximately 0.40 lb (0.20 kg) and uses Viton seal kits for optimal performance. When incorporating the optional T8A pilot control valve, it should be installed after the main stage valve has been correctly torqued. These pilot cartridges are sold separately and offer various operation modes including electro-proportional, solenoid, air pilot, and hydraulic pilot options. All two-port flow control cartridges from Sun Hydraulics are interchangeable within their series, although extension dimensions may vary. The FXDA8BN is particularly suited for applications requiring consistent flow regulation across varying pressures while maintaining high accuracy in the lower two-thirds of its range.
