Installation notes

Installation is permitted from vertical to horizontal relative to the spindle; installation with the spindle pointing downwards is not permitted. Observe the flow direction indicated by the arrow on the body. For medium temperatures of -10...2°C, a valve neck extension is recommended. The permitted medium temperature may depend on the actuator type; limitations are specified in the actuator data sheets.
