How It Works

In systems that require precise mixing of two materials, such as coatings, foams, or sealants, maintaining the correct ratio is essential. This ratio check valve assembly ensures each component flows correctly while preventing backflow or cross-contamination.

By stabilising fluid flow and maintaining consistent ratios, it helps improve finish quality, reduces material waste, and protects system components from damage caused by improper mixing.

Frequently Asked Questions

A ratio check valve ensures that two different fluids maintain the correct proportion while flowing through a system. It also prevents reverse flow and cross-contamination between materials.

No, this is a component-level part used in specific systems. Compatibility depends on your machine’s configuration and parts breakdown. Always verify using your equipment manual or part number.

Stainless steel provides excellent resistance to corrosion, chemicals, and wear, making it ideal for demanding industrial applications and ensuring long service life.

Incorrect ratios can lead to poor mixing, improper curing, reduced coating quality, and potential damage to equipment. This valve helps prevent such issues.
