Installation
The valve can be installed in horizontal or vertical piping. For electrically
actuated valves, the axis of 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.
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.
