About multiposition valves
Dead-end flowpath –
SD configuration
Multiposition valves – low pressure
MW Type
SD valves select one of 4 to 16 dead-ended streams. The selected stream flows from the outlet to a sample valve, pressure sensor, detector, column, etc. The same flowpath can also be used to direct one stream to a number of outlets in applications such as fraction collection. See application suggestion.

Specifications / Product numbers
A complete valve product number includes information about the specific valve, actuator, and mounting hardware. Locate the valve with desired specifications in the chart below and select it to continue to the next step in arriving at the correct product number.
Jump to the valve selection chart.
Actuation
Valves can be automated with pneumatic or electric actuators. Manual actuation is not recommended. Read more about actuators.
Standoffs
Multiposition GC valves usually require a standoff - an extension between the valve and actuator which allows the valve to be mounted in the heated zone while the actuator or handle remains outside at ambient temperature. Standoffs are available in lengths of 2", 3" 4", and 6".
Options
Consult the factory for product number and pricing for the following options:
- Standard valve body material is Nitronic 60 stainless steel. Other materials are available: Hastelloy C, Inconel 600, Monel 400, Nickel 200, Nitronic 50, titanium, and zirconium.
