Eaton Integrated 2FB25 - Flow Regulator - Bypass Style

Application
2FB valves are bypass flow regulators. The flow (and actuator speed) will be largely independent of the load and the pressure conditions.

If used to regulate flow from a fixed supply, for example a standard gear or piston pump, the valve will pass the required flow and any surplus flow will be dumped to the tank line at working pressure. The supply pressure requirement will be approximately 7 bar (100 psi) higher than the system pressure, this being the operating pressure of the valve.

Operation
Inlet flow passes through the adjustable orifice and out of the regulated port. The pressure drop across the orifice is sensed at each end of the spool, producing a force which, at the required flow rate, overcomes the spring force. The resultant movement of the spool regulates the flow by opening the radial valve ports and dumping excess flow.

The valve will pass flow in the return direction but this is restricted by the flow path through the control orifice. For correct valve function the pressure on the tank line MUST be lower than the minimum pressure on the regulated line.
