DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, motorized adjustable pressure reducing, relieving valve, pilot opearated.
OPERATION
The AF-PRP can be adjusted to any position between fully open and fully closed applying electrical power to the
motor. When a pre-determined pressure is reached at (3), the spool shifts to restrict input ow at (2), thereby
reducing (restricting) ow. If valve and pressure at port (3) exceeds setting, spool shift to open passage at port
(1), thereby regulating pressure at port (3) by relieving excess ow.
