Description

The Tridak model 775 is a compact, air actuated, normally closed, spool type shut-off valve that provides precise control over both the rate (adjustable flow gives absolute control over the amount of material deposited during a specific period of time) of flow while operating, and the amount of suck-back (Control over the amount of suck-back is mandatory to achieve consistent string less cut-off of tacky materials and to eliminate air entrapment, and also prevents a droplet from remaining on a dispense nozzle when used with thin materials, both of which drastically effect accuracy and repeatability) when closing. Both controls are conveniently located on the end opposite the material outlet and are lockable to prevent drift or tampering.
