14/36 Variable Leak Valve User Manual / 87-400-085-01 (D)
Flange Connection
The valve is shipped in a closed, leak-tight position, lubricated and
ready for installation.
The ConFlat flange on which the variable leak valve is mounted
mates with any 2 /4 inch O.D. ConFlat flange.
1. Place a new copper gasket (Agilent part no. 953-5014) between
the two ConFlat flanges.
2. Lubricate and install bolts and nuts.
Use Fel-Pro C-100 high temperature lubricant on screw threads
and under the nuts.
3. Tighten each nut 180° apart in sequence to 5 to 8 ft-lbs torque.
This will partially close the gap between the flange faces. Repeat
the sequential tightening two more cycles.
4. The copper gaskets are partially sheared in making the seal and
the bolts should be tightened until the flange faces meet.
5. Leak-check the connection.
Inlet Gas Connection
The connection is made through standard Mini-Con- Flat flanges.
A Mini-ConFlat flange-to-flare-fitting adapter kit (Agilent part
no. 951-5117) is provided as an option.
1. Place a new copper gasket (Agilent part no. 953-5014) between
the two ConFlat flanges.
