Mounting cover of equipment with DN 65 -
100
Attention!
Equipment may leak if the gasket is
damaged.
It is therefore essential that you
always insert a new gasket before re-
attaching the cover.
Make sure that the cover is not tilted
or skewed when refitted.
Clean the gasket surfaces of the cover and
body.
Apply a light smear of lubricant to the threads of
the bolts and the underside the bolt heads.
The lubricant must have the same properties as
OKS 217.
Mount the two covers one after the other. The
following section describes how to mount the upper
cover with the adjustment screw (11). Mount the
lower cover with the adjustment screw (12) in the
same way. The following drawings show the
components of both covers.
Put a new body gasket (31) onto the sleeve (30).
Screw the adjustment screw (11) into the cover
(3) and stop shortly before it hits the stop.
Make sure that the regulator unit (4) is securely
fixed in place.
Carefully place the cover with the regulator unit
onto the body.
