Installation & Operating Instructions
Ball Valve FK 75C and FK 76C
Commissioning – Recommended Practice
When using a valve wrench, the position of the ball valve must be
recognizable by the position of the wrench – for safety reasons:
– Open position: Valve wrench parallel to body/pipework
– Closed position: Valve wrench crosswise/perpendicular (90°) to
the pipework
ARGUS FK ball valves must not be used as throttle or control valves.
