Risk of damage to property and production disruption
Grease can impair the function of the valve. The valve may not open
or close completely.
Coat the sealing rings and threads only with a thin layer of grease.
Follow these steps:
• Carefully insert the valve into the bore of the valve block.
• The valve must be manually screwed into the thread. It must be
possible to screw the valve with minimal effort. Do not damage the
threads in the valve block.
• Tighten the valve in the valve block with a socket wrench to 4.5
Nm.
