Pinch Valves
High Cycle Life
Each valve is factory adjusted to ensure an optimal closing force with the tubing provided. The Silicone Select
TM
and Bio-
Chem (C-Flex) tubing have been specially selected and treated for excellent memory characteristics. The tubing will not stick
shut even after prolonged periods in the closed position. The Silicone Select
TM
tubing is rated for a minimum of 500,000
cycles.
Tubing securely seated without flow restriction
The tubing is seated within a groove in the pinch valve body. The tubing remains securely seated at all times. No
mechanical locking feature is required to retain the tubing during operation. Flow is not restricted when the valve is in the
open position.
Wide assortment of sizes and configurations
Bio-Chem Valve standard pinch valves are offered with tubing internal diameters ranging from 0.010’’ (0.25 mm) to 5/16’’
(7.95 mm). The valves are available in normally open, normally closed, and 3-way (one tube normally open, the other
normally closed) configurations. Dual tubing configurations (two tubes being operated simultaneously) are offered with
smaller tubing sizes. Multi-tube pinch valves with 4.6, or 8 tubes are available in normally open configurations only. Through
Bio-Chem Valve’s Quick-Change Customization™ process, standard pinch valve configurations can be modified to meet
customer specifications. For alternative tubing materials, operating pressures, electrical terminal connectors and other
features, please consult Bio-Chem Valve and Omnifit.
