MANUAL OPERATING LEVER
All NVMZ Series motorised Valves are equipped with a manual operating lever. This lever:
Allows the valve to be opened for system flushing before it is put into operation
Prevents damage to the seating paddle on 3-way valves, and allows flushing of the system by
maintaining the valve in the mid-position
Resets to normal position the first time the valve is powered up.
