Every valve that bears the name Strataflo starts with our proprietary American-made castings, machined to exacting tolerances and built with craftsmanship by skilled hands.

Our Advantage

Our exclusive one-piece poppet, along with other key design features yield numerous advantages over ordinary check valves. You won’t find O-rings in our products!

After assembly, each valve is tested to ensure casting integrity and backflow prevention—only then is it branded with the Strataflo name—your assurance of quality.


Our Story

Beginning in 1939, Strataflo became known for the performance of our innovative and durable rubber poppet. This unique, patented design earned the respect of pump manufacturers and well professionals alike.

Strataflo then designed a metal poppet to solve the problem with metal-to-metal seals. This unique, precision-machined innovation also became a success—this time in oil, gas, and steam applications.

The same maverick spirit of our founding is the driving force behind Strataflo, and it continues to this day—from our relentless pursuit of innovation, to providing customers with the craftsmanship, responsiveness and value they expect from a leader.
