A heavy duty, multifunction, screw-in, cartridge-style, spool-type flow divider/combiner. It provides pressure-compensated proportional division of inlet flow or combining of two return flows regardless of system operating pressure. The FD56-45 has an orifice at Port 1 to facilitate removal of the spring ring if needed.
In the dividing mode, the FD56-45 will divert input flow from 3 to 2 and 4, based on the ratio specified, regardless of operating pressure. When the flow direction is reversed the valve will combine flows from 2 and 4 to port 3. Synchronizing flow is provided in both the dividing and combining modes at "bottomed" conditions in cylinder applications and at stalled conditions in motor applications.
• Hardened parts for long life.
• Quiet, modulated response.
• Wide operating flow range.
• Industry common cavity.
• Synchronizing in dividing and combining modes.
• Floating cage — High installation torque.
