Model A7A Color-Change Valves

nnnn

Fast acting, high-speed valves with carbide ball and seat

nnnn

for positive shut-off and long life in abrasive coating applications.

nnnn

Features and Benefits

nnnn

■ Standard high-pressure valve - includes integral

nnnn

outlet check valve to prevent material from

nnnn

entering valve for contamination protection.

nnnn

■ Quick and simple retrofit - to existing

nnnn

installations provides fast color change

nnnn

and improves production efficiency.

nnnn

■ Air-actuated valves - promote safe operation

nnnn

even in hazardous areas with no ignition risk.

nnnn

■ Modular "stacking" manifold design -

nnnn

allows for future expansion of additional colors

nnnn

to meet new production requirements.

nnnn

■ System compatibility - can be used with most

nnnn

coating equipment, including air-spray, rotary atomizer,

nnnn

air-assisted airless, HVLR and high-pressure

nnnn

airless systems. The pressure rating is 1500 PSI

nnnn

for standard valves; 3000 PSI for valves with the optional

nnnn

high-pressure closure spring kit.

nnnn

■ Carbide ball and hardened seat design - of high speed

nnnn

A7A valve ensures fast actuation and long life in abrasive

nnnn

coating applications.

Nordson Model ATA color-change valves deliver fast and

nnnn

reliable color-change performance for improved productivity

nnnn

and maximum operating efficiency. They respond to

nnnn

pneumatic signals and feature a carbide ball and seat for

nnnn

positive shut-off and long service life when used in abrasive

nnnn

coating applications. The ATA valves can also be used with

nnnn

custom-designed manifolds.
