Pressure control valves (PCV)
ÄKTAprocess can be provided with up to two optional pressure control valves, PCV-341
and PCV-342, as shown in the illustration below.
The illustration shows PCV-341 and PCV-342 positioned horizontally.
Note:
The function of the PCVs is to protect the system from 'free flow' if the inlets are fed with
a higher pressure than 0.2 bar.
The pressure control valve option allows the pressure on the inlets to be regulated and
the flow through the system via individual system pumps to be controlled.
ALP2 PCV safety monitoring
If ÄKTAprocess is optionally configured to include a pressure control valve, or valves, the
system will also be equipped with an ALP2 air, level and pressure monitoring system.
The ALP2 unit protects against exceeding maximum operating pressures by monitoring
pressure between the pumps and the PCVs.
