Series 20
The Brand, Series 20 Sectional Directional Control Valves are assembled to meet our customer’s requirements for up to six individual applications per assembly (consult factory for more sections). Brand Hydraulics does not charge anything extra for this process and assembly is priced solely on the overall sum of the prices of its components.
When assembled in their normal manner the series 20 spool sections are in parallel. When the spools are in neutral position, the 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. All spools are machined with metering chamfers, and have a high "handle vs. spool" movement ratio, resulting in good metering capability. Input flow can be divided among several circuits (spool sections) by feathering the spools.
