Principle of operation
The process medium flows through the valve in the flow-to-open
Direction. The position of the valve plug determines the
Cross-sectional area of flow between the seat and plug. The CIR -culation inhibitor at the bottom minimizes the effects of the me -dium flow in the insulating section.
Fail-safe positions
Depending on how the compression springs are arranged in the
Actuator (see Data Sheets T 8310-1 EN and T 8310-2 EN for
Details), the control valve has two different fail-safe positions
Which become effective upon supply air failure:
Actuator stem extends (FA)
The actuator springs close the valve when the supply air fails.
Actuator stem retracts(FE)
The actuator springs open the valve when the supply air fails.

Installation in the pipeline
It is not necessary to remove the insulating section to weld the
Body in the pipeline.
Please note that the temperature at the point of connection from
The valve body to the insulating section must not exceed 220 ° C.
