Change-over valves

Differential pressure switch

Hydraulical or electrical change-over valves
are used in SKF DuoFlex dual-line centralized lubrication systems to control main feed
lines 1 and 2. Starting from the lube pump,
the main lines are alternately used as pressure (P) and return (R) lines.

The differential pressure switch is used to
optimize the changeover from line 1 to
line 2. It is used in dual-line systems with
long lines and very low temperatures. It is
installed upstream of the dual-line distributor farthest from the pump to ensure sufficient pressure to all dual-line distributors
even under low temperature conditions and
with long feed lines.
