The Model V9-8 and Model AV9-8 Stream Select Valves are high pressure, 9-port, 8-position valves for stream
selection. The valves are rated at 1000 psi (max.). The 8 ports (labeled 1 through 8) provide bi-directional fluid
flow. The ninth port is the central common port located at the base of the valve. The fluid pathway is chosen
either by manually turning the valve arm on the Model V9-8 until the port indicator window shows the desired
port or by initiating a command from the Controller to the Model AV9-8. Note that for the AV9-8 the default
position at system power up or at the conclusion of a run, is position 1 (Ports 1 and 9 connected). Refer to the
BioLogic Instruction Manual for discussion of software control of the valve.
