Based on the time-pressure dispensing principle, the needle dispensing valves are most effective in continuous applications of low to high viscosity media. Consisting of two structurally separate parts, they have the advantage that material cannot leak into the drive cylinder and interfere with the valve needle movement. The size of the orifice is regulated simply by a stop screw. A special, adjustable seal closes the valve needle off from the valve head, ensuring a perfectly clean and precise application of every single shot. The material passageway can be flushed as and when necessary.

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.
