N-Series Isolation Poppet Valves
5.2 Valve Installation
Every N-Series valve is packaged with plastic protective flange end-caps. Leave these caps in place until the product is ready to be installed in the piping mani-
fold or vacuum system. Even the smallest scratch or nick on the flange sealing surface can significantly compromise the leak integrity of the vacuum system and
cause inadequate pump-down performance.
Be sure to always use the proper Nor-Cal flange connection hardware, including centering rings, O-rings, copper gaskets, clamps, nuts and bolts, etc.
CAUTION: BENDING MOMENTS: Improper installation of the N-Series valve may lead to failure of the valve to seal or permanent damage
to the valve housing body. Bending moments across the inlet and outlet flange connections should never exceed 50 ft-lb. Never
force two tube ends together with clamps or fastening hardware. Doing so will likely damage components in the line, such as a
valve. Instead, make use of flexible couplings to help join slightly misaligned sections of vacuum tubing.
5.3 Pneumatic Hook-Up
The standard N-Series valve comes equipped with a quick disconnect fitting. Use 5-32” [4mm] OD flexible tubing to supply compressed air to the valve.
Alternate tubing connections can be accommodated by replacing the quick disconnect fitting. The valve stem thread is 10-32 [M5].
