The Brand, Series 21 Direct Acting Solenoid Operated Stackable Directional Control Valves are
assembled to meet our customerís requirements for up to six individual applications per assembly.
Brand Hydraulics does not charge anything extra for this process, an assembly is priced solely on the
overall sum of the prices of its components.
When assembled in their normal manner the Series 21 spool sections are in parallel. When the spools are in the neutral position flow passes by each spool and then onto the tank (outlet) port. If two or more spools are shifted simultaneously their work ports are in parallel. The oil flow will take the path of least resistance allowing lighter loads to move first.
