Figure 13. Replacing molbloc-S Flanges
Using a 3 mm hex wrench, remove and preserve the socket head caps
screws that retain the existing VCR inlet end flange. DO NOT remove the
downstream end flange.
Preserve the end flange face seal, Viton
®
O-ring ( DHI P/N 102221) Parker
P/N 2-022, for use with the new flange. Be careful not to damage this seal in
any way, as a leak can result which will cause errors during flow measurement.
Position the replacement VCR inlet flange on the end of molbloc-S, making
sure that the flange seal is in its proper location, and be sure not to “pinch”
the seal between the flange and body.
Thread each of the socket head caps screws into the body, but leave loose
enough to allow adjustment in the flange’s final position.
Tighten each of the screws in a “star” pattern a little at a time. Finish by
tightening to a torque value of 3 Nm on each screw.
