numbered in sequence CCW. Inlet ports use fittings with short nuts, and
are equipped with filter unions.

When plumbed for continuous flow operation, this valve allow sample gas to flow
continuously from inlet to outlet, ensuring that fresh sample gas is available at
the mass spectrometer at all times. When this port is selected for sampling, the
gas is routed to the mass spectrometer instead of to the outlet port. In cases
where continuous flow is not desired, such as for ports with calibration gases
connected, the outlets should remain plugged. Valve(s) are shipped with plugs
installed in both inlets and outlets.
Refer to the following diagrams for information on rotary valve options.
