c) Manometer Mounting Port
On the end cap of the hydraulic valve bank, there is a nominated “GA”
port that is used to install a pressure gauge. This gauge monitors
the hydraulic oil pressure which is delivered from molding machine,
or pumping power station, to the valve bank. The pressure will be
reduced to 45-50 bar (653-725 PSI) by the PRV before sending to
actuators. If you need to monitor and manipulate the actual hydraulic
pressure that is driving the actuator, there are two ports that can be
used to install the pressure gauge.

d) Manual Override Pin
This allows you to push the spool to reset the valve in emergency
conditions, for example, when there is a power shortage the solenoid
cannot be energized.
