Product information "2K Valve ID2/2"
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.

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.
