Operation
The valve is operated by handwheel (ON 13 3110), chainwheel
(ON 13 3130) or from a stand (ON 13 3140 and ON 13 3142). The type of electric actuator and maximum pressure drop is selected by the
supplier.

Testing
The valve is tested as per ÈSN 13 3060, part 2, DIN 3230-3.
Installation
The valve can be installed in horizontal or vertical piping. For electrically actuated
valves, the axisof electric motor must remain
horizontal. If an actuator is fitted with el. motor which axis is vertical, amount of oil fill
must be increased. If the valve is installed
horizontally, the actuator must be supported.
