Description
Solenoid actuated relief valve.
Operation
This standard valve package is
designed for pump unloading
via solenoid valve activation
and pump relief, when the
solenoid valve is not activated
and system pressure reaches
relief valve setting.
Features
Normally closed and normally
open options, tamper proof or
adjustable relief options. Low
power requirements, gauge
port. Aluminum in-line type
housing, number of voltage
and connector options.
All components in the package
are true cartridges and can
be removed from the housing
without disturbing the plumbing.
