Model 11 Valve

This section presents information to disassemble, clean, and rebuild the Model 11 Valve
(including the Model 11 Low Dead Volume Valve).
The Model 11 valve (M11) is available in two primary types, the standard Model 11 Valve and
the Model 11 Low Dead Volume (LDV) valve. The primary difference between the Model 11
and the Model 11 LDV valves is the sample ports on the valve cap. The sample ports on the
Model 11 valve have tubing connected as part of the cap. For the Model 11 LDV the ports are
threaded holes and tubing is not part of the cap. Within this section, steps for these two types
of valve are the same except where noted.
Further maintenance procedures for these valves, including port-to-port leak tests, are
available in the Model 11 Valve Repair Manual (PN M06115) and the Model 11 LDV Valve
Repair Manual (PN 2015584-001).
