Installation and use notes
Permitted installation position: from vertical to horizontal in relation to the axis; installation with the axis pointing downwards is not permitted. Observe the flow direction indicated by the arrow on the body.
At a fluid temperature of -10...2°C, stem heating or a valve neck extension is recommended. The permitted fluid temperature may depend on the actuator type; limitations are specified in the relevant actuator data sheets.
