Valve Restrictors:
The Restrictors Vary in size from Spool to Spool, Some Ports do not use restrictors at all,
See parts page for types and sizes. Restrictors operate by controlling the rate of flow to or
from a Cylinder, This is most commonly done by the size of the Hole the Oil is sent through,
But can be done by Hose Size. There are also 1 way and 2 way restrictors, Check Parts
pages. DO NOT Remove, Change or Modify Restrictors.
