Notes on Installation
GEA Tuchenhagen recommends that the valve should be installed vertically (actuator
up, housing bottom). If the control valve is not installed vertically, the stress on the valve
stem seals is higher than when installed vertically. Therefore, regularly check the control
valve for leakage.
To prevent damage, make sure that
• the valve is installed in the pipe system free of tension and
• no foreign materials (e.g. tools, bolts, lubricants) are left in the system.
