DESCRIPTION
16 size, 1 5/16-12 thread, “Super” series, motorized adjustable pilot-operated pressure relief valve.
OPERATION
The AJ-RVR blocks ow from (2) to (1) until sufcient pressure is present at (2). The setting of the AJ-RVR can be
adjusted to any value between 14 and 245 bar (200-3500 PSI) applying electrical power to the motor. The setting
does not change unless the electrical motor is activated. Reverse ow (1) to (2) occurs when the pressure at (1)
is at least 2.1 bar (30 PSI) higher then at port (2).
