PRESSURE RELIEF VALVE
IDENTIFICATION
FIN: 1063GM
LOCATION
ZONE: 146
DESCRIPTION
The pressure relief valve protects the system from
overpressure.It opens at 237 bar (3436 psi) and closes
at 220 bar (3190 psi).
LEAKAGE SOLENOID VALVE
IDENTIFICATION
FIN: 1150GP
LOCATION
ZONE: 146
DESCRIPTION
The leakage solenoid valve controls the fluid flow to
the leakage measurement system manifold.It is normally
open. During ground operation of the system, the valve
is closed to connect the HP outlet port to the return
circuit and thus shuts the HP inlet port.
