With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. Also known as pinch valves, they press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.

Valves with a closed body securely hold tubing in place.

Valves with an open body provide easy access to tubing for maintenance or replacement.

Tabs have flow-adjustment notches that allow you to lock in adjustments.
