Model A7A Color-Change Valves
nnnnFast acting, high-speed valves with carbide ball and seat
nnnnfor positive shut-off and long life in abrasive coating applications.
nnnnFeatures and Benefits
nnnn■ Standard high-pressure valve - includes integral
nnnnoutlet check valve to prevent material from
nnnnentering valve for contamination protection.
nnnn■ Quick and simple retrofit - to existing
nnnninstallations provides fast color change
nnnnand improves production efficiency.
nnnn■ Air-actuated valves - promote safe operation
nnnneven in hazardous areas with no ignition risk.
nnnn■ Modular "stacking" manifold design -
nnnnallows for future expansion of additional colors
nnnnto meet new production requirements.
nnnn■ System compatibility - can be used with most
nnnncoating equipment, including air-spray, rotary atomizer,
nnnnair-assisted airless, HVLR and high-pressure
nnnnairless systems. The pressure rating is 1500 PSI
nnnnfor standard valves; 3000 PSI for valves with the optional
nnnnhigh-pressure closure spring kit.
nnnn■ Carbide ball and hardened seat design - of high speed
nnnnA7A valve ensures fast actuation and long life in abrasive
nnnncoating applications.

nnnnNordson Model ATA color-change valves deliver fast and
nnnnreliable color-change performance for improved productivity
nnnnand maximum operating efficiency. They respond to
nnnnpneumatic signals and feature a carbide ball and seat for
nnnnpositive shut-off and long service life when used in abrasive
nnnncoating applications. The ATA valves can also be used with
nnnncustom-designed manifolds.
