Dispense Valve System Model 455
Description

The patented model 455 valve is a pneumatically operated, normally closed pinch-type valve that features micrometer control over the amount of flow (the amount the tube opens) and precise control over tube closure (insures the accuracy and repeatability of operation and greatly extends pinch tube life.) Although tubing constructed of Teflon® is the recommended standard, the 455 valve is supplied with all the components required for the valve to be used with silicone, urethane or vinyl tubing. The 455 valve can be used as a dispense valve or as an in-line, two-way (on-off) valve with adjustable flow. A Tridak controller or a user supplied device can be used to operate the valve.
