- Pinch valves (Manual, Automated & air operated)

- Slurry knife gate valves (up to 50 Bar)

- Vacuum preventing and Air release valves. (up to 100 bar)


Founded in 1993 in Maryland and Finland, RF VALVES, INC. was built on an idea for a better pinch valve. 
The concept of an innovative expansion fold in the elastomer tube that would lasts 2 to 4 times longer than traditional tubes and a pinch valve design that allows for in-line tube replacement, cutting maintenance time by 75% was all it took for the company to take off. Engineers in a wide range of industries were thrilled with the valve’s performance, and still are today.
