Flow Restrictor Valve Replacement
If the flow restrictor valve Figure 4-4 needs to be removed or replaced, it is important
that it be properly reinstalled. The valve will be marked either with an arrow or with the
word “IN”. If marked with an arrow, the arrow must point away from the hydraulic cyl-
inder port. If marked with the word “IN”, the end of the valve marked “IN” must be to-
ward the hydraulic cylinder port. Only a 1/4 inch NPT hydraulic elbow should be con-
nected between the hydraulic cylinder port and the end of the flow restrictor valve.

Improper installation of the flow restrictor valve or the use of the wrong size elbow will
permit widely varying rates of descent and may result in near free-fall in case of hose
failure.
