About multiposition valves
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.
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.

Valves can be automated with pneumatic or electric actuators. Manual actuation is not recommended. Read more about actuators.
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".
For specific product numbers, select a valve specification below.
