The Sun Hydraulics FXFALBV (FXFALBV) is a fixed orifice, pressure-compensated flow control valve designed for precise flow regulation in applications with significant pressure fluctuations. This valve is suitable for both meter-in and meter-out flow control scenarios, ensuring consistent performance regardless of varying pressures. The user specifies the flow setting, which is factory set to within 10% of the requested specification. Additionally, there is an adjustable control option that allows for a 20% variation from the nominal factory preset flow rate. The design features a sharp-edged orifice that minimizes variations in flow due to changes in fluid viscosity. All Sun Hydraulics 2-port flow control cartridges are interchangeable, maintaining the same flow path and cavity dimensions across different frame sizes, although the extension dimensions from the mounting surface may differ. The FXFALBV model incorporates Sun's floating style construction, reducing the risk of internal component binding from excessive installation torque or machining variations in cavities or cartridges. Key specifications include a T18A cavity, Series 4 classification, and a capacity of up to 50 gpm (200 L/min). The maximum operating pressure is rated at 5000 psi (350 bar). Installation requires a valve hex size of 1-5/8 inches (41.3 mm) and torque specifications range from 350 to 375 lbf ft (475 to 508 Nm). An internal hex size of 5/32 inches (4 mm) is used for adjustment screws, while locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). Weighing approximately 2.80 lb (1.30 kg), this model also supports Viton cartridge seal kits for enhanced durability and performance.
