The Sun Hydraulics FDCBYAV (Material Number: FDCBYAV) is a fully adjustable, pressure-compensated flow control valve designed to provide precise flow regulation for both meter-in and meter-out applications, especially in scenarios with wide pressure fluctuations. This model features a reverse-flow check that allows for unrestricted flow from port 2 to port 1, thanks to its integral high-capacity check valve. With its balanced adjustment mechanism, the valve can be easily adjusted even under high pressures. The sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity, while the minimum leakage rate is .2 gpm (0.8 L/min) when the adjustment mechanism is fully closed. Physically and functionally interchangeable with other 2-port flow control cartridges of the same frame size, this model uses a T5A cavity and belongs to Series 2 with a capacity of 12 gpm (45 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open. Installation requires a torque of 45-50 lbf ft (61-68 Nm), and the valve hex size is 1-1/8 inches (28.6 mm). The locknut hex size is 9/16 inches (15 mm), requiring a torque of 80-90 lbf in (9-10 Nm). This model weighs approximately .60 lb (0.30 kg) and can be fitted with Viton seals using seal kit number 990203006 for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it may damage the seals. This product is ideal for applications requiring consistent flow control under varying conditions, ensuring system efficiency and reliability.
