Eaton Flow Controls F(C)G 3, 10 Series

in

These pressure compensated valves are designed to provide adjustable controlled flow rates independent of changes in inlet and/or outlet pressures above a minimum pressure differential. Models are available with or without integral reverse flow check valves. Those with check valves are optionally available with an anti-jump feature designed to eliminate transient surges above the controlled flow rate setting whenever flow is first directed to the inlet port A.

All models have rotary adjustment of controlled flow and can be supplied with or without an integral key-lock feature. The construction of a typical model with integral check valve and anti-jump feature is shown opposite. Its operation is the same as for similar valves described in the “Industrial Hydraulics” manual although the spring-loaded hydrostat is functionally located downstream of the adjustable restrictor, as shown in the “Functional Symbols” section available for download.
