FDC16 Flow Divider/Combiner (FDC16)
A specialized flow divider/combiner valve manifold, commonly applied in hydraulic motor drive applications with uneven pressure loads caused by steering or ground conditions. This valve/manifold assembly uses the FD56-45 cartridge valve; see page 5.636.1.
Product Operation
In the dividing mode, the FDC16 will divert input flow from valve port 3 (V) to ports 2 (C2) and 4 (C1) based on the ratio specified, while pressure at 2 and 4 remains relatively equal. If a pressure differential develops, fluid will be transfered to the lower pressure port from the higher pressure port via an internal body orifice: 4 to 2 or 2 to 4.In the combining mode, the internal orifice will serve to equalize load pressures, preventing combiner spool lock-up.
Product Features
• Hardened parts for long life.
• Quiet, modulated response.
