DE-RVB CROSSOVER RELIEF VALVE, FOR PARALLEL CIRCUITS
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, crossover relief valve for parallel circuit applications.
OPERATION
The DE-RVB is a direct-acting, cross over relief valve. When pressure at either port exceeds the nominal setting
value, ow will be diverted to the opposite port. Back pressure at either port will affect the nominal setting of the
opposite port on a 1:1 basis. For correlation purposes, pre-set value will be measured at port (2). Pressure at port
(1) will not vary more than ±300 PSI from the port (2) value. The cartridge offers smooth transition in response to
load changes in common hydraulic circuits.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
