Model 775
Model 775 Dispensing Valve with Suck-Back and Flow Controls
The Model 775 is a pneumatically operated spool valve that is designed to accurately dispense a variety of low, medium and high viscosity fluids. This products superior accuracy comes from two main features, its suck-back control, and adjustable flow control. The suck-back feature greatly increases accuracy and repeatability when dispensing materials. Having control over the amount of suck-back assures consistent, stringless dispensing of tackier materials, and prevents droplets from remaining on the dispense nozzle when using lower viscosity materials. The valves other key feature, adjustable flow control, gives users the ability to have complete control over the amount of material dispensed. This product can dispense volumes as little as 0.01 mL and as large as 50 mL.
The Model 775 dispensing valve is ideally suited to automated applications, but can also be paired with the Dymax DVC-345 Digital Valve Controller and a material reservoir to create a bench-top dispensing system.
Features
Features
- Adjustable suck-back provides a crisp, clean shut-off of materials eliminating droplets and skinning-over at the end of the dispense tip
- Available with PTFE non-stick coating or fluoroelastomer o-ring seals for compatibility with a larger variety of fluids
- Adjustable flow control with lock provides accurate dispensing in shots from 0.01 mL to 50 mL
- Adjustable flow control lock prevents drifting or tampering
- Dispenses from pressurized cartridges, bottles, and pails (requires appropriate reservoir hardware) for compatibility with most standard fluid packages and delivery systems
- Lightweight so it’s easy to handle and mount in automated or bench-top systems
