Brand Hydraulics FC (Low Flow 0-30 gpm)

The Brand, full range pressure compensating variable flow control is designed so that the orifice area varies as the lever is rotated. Fluid travels past the variable orifice, through the compensator spool and then out the controlled flow port. Therefore the flow out of the CF port is proportional to the orifice area which can vary from closed to open. The sum of the controlled flow and the excess flow equal the inlet flow and as the controlled flow increases the excess flow decreases. Both outlet flows are pressure compensated with a spool that maintains a constant flow while adjusting for pressure. Hunting between the compensated pump
and our valve is dampened with a dashpot on the compensator spool. Thus, the outlet flow is smooth and constant regardless of the pressure on the CF and EX port. External seals on the side lever spool prevent contamination from getting between the spool and the casting, thus preventing the spool from locking in one position. Please consult the factory for stainless steel side lever spools when the valve is going to be used in a corrosive environment. We also offer the FC with outlet ports coming from the top of the casting.
