Our Pressure Relief Check Valves at a Glance

  • Custom check valves from Smart Products USA offer customizable components, precise opening pressures, and a wide range of styles, making them ideal for low-pressure, low-flow applications.
  • These valves are economical, available in FDA- and NSF-compliant and corrosion-resistant materials. They have a temperature range from -40 °F to 400 °F, which means they can be used successfully across a variety of industries and applications.
  • Featuring low-inertia poppets for quick sealing, many of our check valves can also function as pressure relief valves.
  • As an OEM check valve manufacturer, our emphasis is on quality, and we provide special services like cleanroom molding, specialized testing, and hot melt gluing.

People Often Ask, What Makes Your Custom Check Valves Smart?

The answer is the ability to take customizable components, like the plastic body material and O-ring, and pair them with a precise opening pressure. This custom configuration coupled with a wide range of styles allows for millions of possible combinations to create an accurate and reliable low-pressure, low-flow check valve for a specific criterion.

Ideal for liquid or gas applications, our valves are featured in every industry, economical, FDA and NSF compliant, corrosion resistant, and able to withstand operating temperatures ranging from sub-zero to 400 °F depending on the materials specified. The thermoplastic materials used in these check valves with pressure relief provide improved corrosion resistance and make them a superior alternative to comparable metal valves.

The majority of our check valves incorporate a low-inertia poppet with double-tapered O-ring seats to achieve a fast, positive seal in ultra-low-pressure applications. Additionally, most of our pressure control check valves can also be used as pressure relief valves as long as the O-ring side vents to the atmosphere.

To ensure optimal valve performance every time, it is important to communicate any liquids/gases used, application environment, and intended shelf life. The more we know about your low-pressure, low-flow needs, the better equipped we will be in selecting the right components to create a precise and accurate product exclusively for your application.
