This is a Lock & Cancel Valve used in many pneumatically controlled instruments.Its function is to turn off and on instruments/pneumatics with on and off signals from the roll frame. The 5/32" elbow on top of the valve allows the vacuum to flow threw the valve to operate pneumatics that control instruments. A signal given to the bottom valve will stop the flow of vacuum. These units are built with adjustable Wurlitzer type valves.
Note: These valves DO NOT COME WITH THE BASE PICTURED. We can customize anything you wish. Just make a request.
