RE 18321-30/03.2016, Bosch Rexroth Oil Control S.p.A.
Description
A constant flow rate, regardless of system pressures, is
established from 1 to 2 while a minimum pressure
differential of 14 bar (200 psi) exists between the two
ports. Output flow can be varied from closed to the
nominal maximum rating for the valve. Free flow is
permitted from 2 to 1, regardless of valve adjustment, by
when pressure overcomes the spring bias of the valve
check function.
Flow control, 2-way pressure compensated,
fully adjustable, free reverse flow
Common cavity, Size 12
