Oilstop V anti-siphon valve
Operation
8. Operation
•
During operation, the valve does not require any action.
•
The valve can be shut off for work on the suction pipe. To do so, set
the scale to “absperren” (shut off) by turning the handwheel. After
having completed the work on the suction pipe, set the scale back to
the required protection height.
