The Graco 02/0726-S/50 Valve Assembly Ratio Check 1/4 SS is a component-level part used across multiple Graco plural-component and fluid handling systems. It is not limited to a single machine but is commonly found in the following equipment types:
The Graco 02/0726-S/50 Valve Assembly Ratio Check 1/4 SS is a precision-engineered ratio check valve designed to maintain accurate fluid proportions in plural-component systems. Built with durable stainless steel, it ensures long-lasting performance in demanding industrial environments.
This valve plays a critical role in preventing backflow and maintaining consistent ratios between two materials, helping to ensure proper mixing, reduce waste, and improve overall system reliability.
| Part Number | 02/0726-S/50 |
| Type | Ratio Check Valve Assembly |
| Port Size | 1/4 inch |
| Material | Stainless Steel (SS) |
| Function | Maintains correct fluid ratio and prevents reverse flow |
| Application | Plural-component and fluid handling systems |
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.
