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

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.

Line body construction allows direct connection into hydraulic systems. Leak-proof adjust screw gives easy, accurate adjustment to required flow setting. Hardened and ground working parts give accurate flow control and long working life.
