Over 3 Million Possible Combinations!

Create your own custom configured check valves and pressure relief 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. All Smart Products check valves are ideal for use as pressure relief valves.

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.
