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 single-component (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. The snuff-back mechanism effectively prevents material from dripping after shot completion. This valve is exceptionally easy to maintain.
