RE 18321-20/03.2016, Bosch Rexroth Oil Control S.p.A.
Description
A constant flow rate, regardless of system pressures, is
established from 1 to 3 while a minimum pressure
differential of 14 bar (200 psi) exists between the two
ports. Input flow supplied to 1 in excess of the regulated
output at 3 is by-passed to 2. Output flow can be varied
from closed to the nominal maximum rating for the valve.
Flow from 3 to 1 is limited by the diameter of the selected
control orifice and is not pressure compensated. Flow from
2 to 1 is not permitted.
Flow control, 3-way pressure compensated,
combination type fully adjustable
Common cavity, Size 10
