Internal Actuators; Solenoid Valve With Tuning Valve - Getinge Applikon my-Control Hardware Manual

The my-Control may be equipped with different internal actuators for aeration and addition of liquid:
• Solenoid valve with tuning valve per gas inlet line (nitrogen, air, oxygen and carbon dioxide)
• 1-channel or 3-channel mass flow controller
• Tubing pump for liquid additions
Gasses that are used for aeration and pH control (CO
-Required inlet pressure for the gasses: 2 barg.
-Required quality of the gasses:
A micro valve may be applied as external actuator. Refer to the section about the micro valve.

SOLENOID VALVE WITH TUNING VALVE

Per gas inlet line, inside the my-Control a solenoid valve may be installed. The individual gas flows can be
manually tuned by a Needle Valve Module. The needle valve module includes a Non-Return valve that
prevents back-flow of gas.
By default, the tuning valve is set to the required gas flow.
Changing the tuning valve setting must only be performed while using a flow meter.

*Additional (needle ) valves must be installed by a certified Service Engineer.
For gas flows up to 200 ml/min, a precision metering valve is
available for more accurate gas flow regulation:
This metering valve is located inside the Control Console cabinet.
Changing the default gas flow requires opening the cabinet and
must only be performed by qualified personnel.
