Pinch Valve Selection Guide
Valves with Bio-ChemValve™ silicone or C-Flex® tubing
1.
Select the tubing material – either silicone, C-Flex® or tubeless. (See page 18 for additional information about these tubing material
options.)
2.
Choose your required tubing internal diameter or flow rate, then flow configuration - normally closed (NC), normally open (NO), 3-way or
multi-tube
3.
Turn to the pages indicated to see full details and ordering information for each valve.
Tubeless pinch valves
Bio-Chem Valve™ Pinch Valves can be supplied tubeless. These valves are manufactured identically to the silicone tubing version and are
supplied without tubing. The designation for these valves is xx#, where xx is the size of tube that should be used.
Valves for customer-specific tubing
If the customer intends to use the pinch valves with tubing other than Bio-Chem Fluidics-supplied tubing, this can be easily accommodated.
The customer should provide a sample of tubing to Bio-Chem Fluidics, who will select the appropriate valve size and adjust the stroke and
force settings to match the tubing diameter and durometer.
Bio-Chem Fluidics will assign a special part number to this valve - contact your local office for more details.
