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).
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.
- O-ring ports eliminate leakage
- Metering spools provide smooth control of load
- Enclosed handles increase handle rigidity and eliminate exposure to the elements
- Individual load check built into each section to prevent the load from dropping when the spool is shifted
- All sections and assemblies are 100% tested including both internal and external leakage and flow tests
