Safe and Durable Designs

At Atmo-Seal, Inc. we know delivering and routing your sample isn’t child’s play. Our heated valve arrays are tough and yet easily maintained.

Our heated valve array exterior enclosures are constructed from aluminum, stainless steel, high-temperature phenolic plastics and other low thermal-transmission materials. These create an attractive, durable and safe design.

The internal sample paths are constructed entirely from stainless steel, and the valve seats are typically Viton, Teflon or Silicone.

Like all of our products, our heated valves carry a full 18 month limited warranty.
