Nordson EFD provides a complete line of 2K modular
metal valves that can be easily disassembled and
cleaned after mixing. Maintaining valves that handle
reactive resins can be time-consuming and expensive
— a plugged valve translates to lost production, and
even a partially plugged mixer results in poor quality.
Features and Benefits
• Eliminate solvent ushing
• Less adhesive waste
• Cleans up easily for increased productivity

If you’re using a meter mix valve, your system may include a valve, mixer,
and accessories. Here are steps to help you select the best possible 2K
meter mix system.
Step 1: Select the Best Spiral Mixer for Your Material
See 2K Selection Guide,
Best Mixer for Your Material.
Keep in mind, when using a meter mix system,
you must use spiral mixers.

Step 2: Select the Best Spiral Mixer for Your Material Viscosity
See 2K Selection Guide,
Best Mixer for Your Material Viscosity.
Material viscosity will help determine
the type of spiral mixer you need.
Step 3: Select Your Meter Mix Valve
Nordson EFD’s meter mix valves are designed to bring the reactive adhesives and sealants into
the static mixer and are engineered for easy disassembly and cleaning. Our pneumatic valves help
increase productivity and eliminate the need for solvent ushing.

Pneumatic Meter Mix Valve Series
Pneumatic meter mix valves provide ON-OFF functions, and metering in the proper ratio of
A and B components is controlled by the metering pumps. Different manifolds are offered
to assist this metering process. The selection of the manifold for each application depends
on the ow rate, viscosity, and volume ratio.
