Remarks. 1. A filter must be installed upstream of the regulating valve.
2. For temperatures around the valve exceeding 150 °C (steam pressure > 4 bar), a cooling element must be installed.
3. The valve must be used together with its actuator. Failure to comply with this point may cause leakage through the stem.
