Installation notes

Permitted installation position: from vertical to horizontal relative to the axis. Do not install with the axis pointing downwards. Observe the flow direction indicated by the arrow on the body.

At fluid temperatures of -10...2°C, stem heating or a valve neck extension is recommended. The permitted fluid temperature may depend on the actuator used.
