The Sun Hydraulics FCBBKAV (FCBBKAV) is a fixed orifice, pressure-compensated flow control valve designed to provide precise flow regulation for both meter-in and meter-out applications, particularly in scenarios with wide pressure fluctuations. This model features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. Users must specify the desired flow rating, which is factory-set within a 15% tolerance of the requested setting. The tuneable control option allows for a 20% variation from the nominal factory preset flow, with adjustments made by turning the screw clockwise to increase flow. All two-port flow control cartridges are interchangeable in terms of physical and functional design, although cartridge extension dimensions may vary. The sharp-edged orifice design minimizes variations due to viscosity changes, while the floating style construction reduces the risk of internal parts binding due to excessive torque or machining variations. The valve fits into a T-162A cavity and belongs to Series 0 with a capacity of 3 gpm (11 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's hex size is 3/4 inch (19.1 mm), and it requires an installation torque of between 20 and 25 lbf ft (27 to 34 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm), requiring a torque of between 80 and 90 lbf in (9 to 10 Nm). The model weighs .30 lb (.15 kg) and uses Viton seals as part of its cartridge seal kit.
