Valve heating

The advantage of diaphragm dispensing valves is their ability to process material with challenging properties in continuous shot applications. The valves are designed for care-free dispensing of low to high viscosity, filled or unfilled, abrasive or chemically reactive 1K fluids. Part of their structure is an integrated diaphragm that separates the pneumatic and the metering parts of the valve. As a result, only the valve head and the diaphragm come in contact with the material, while the material passageway can be easily flushed if necessary. The size of the orifice is regulated by stroke adjustment. Material dripping after shot completion is effectively prevented by the snuff-back mechanism. This valve is exceptionally easy on maintenance.

DOPAG 2K valves are used to process 2K materials with similar viscosities and a relatively long pot life. Recommended mixing ratios are from 100:100 to 100:20. The static mixing system consists of pneumatic driven snuff back piston and a plastic mixer. Due to the infinitely adjustable snuff back function dripping is avoided when metering ends. Different sealing and material versions for chemically aggressive and abrasive 2K materials are available.
