Over 3 Million Possible Combinations!

Create your own custom configured check valves.

Unique in the industry, Smart Products liquid and air plastic check valves provide improved corrosion resistance, which makes them a superior alternative to comparable metal valves. Designed to allow a virtually limitless number of possible combinations, Smart check valves fit a wide range of applications – medical diagnostic and treatment, gas analysis, filtration, beverage dispensing, printing and many others.

For ultra low-pressure applications, many Smart check valves incorporate a low inertia poppet design with double-tapered o-ring seats for a fast, positive seal.

With our custom design and assembly capabilities, special testing, and over 3 million possible combinations from which to choose, we're sure to have just the right configuration to meet your specific design requirements. Our wide range of plastic, o-ring, and spring materials allow you to design your own “custom valve”…without a custom price.
