We offer the Armstrong International line of pressure reducing valves (PRV’s) and temperature regulators for Steam, Air and Water applications. The family of products consists of Direct Acting, Internally Piloted Piston-Operated and Externally Piloted styles. The Direct Acting version requires no external sensing lines and has an accuracy of +/- 10%. The Internally Piloted Piston-Operated models also require no external sensing line but are more complex with a separate pilot and main valve. They have an accuracy of +/- 5%. Finally we have the Externally Piloted style valve which requires a sensing line. This gives the unit a higher accuracy at +/- 1%.

Armstrong advantages include:


Convoluted phosphorus bronze bellows on direct acting valves for more compact designSS stem and bronze body to minimize galling that occurs in conventional valvesIntegral mesh strainerPlastic adjustment cap that does not absorb heat allowing set point changes easilyInterchangeable range springs for field changeover


Enclosed spring chambers to eliminate foulingSingle seated main valve for dead-end serviceMain valve and seat are serviceable with the body still in-lineCarbon piston rings to minimize seizing / stickingInlet screen minimizes fouling of the pilot due to dirt


Ductile Iron body for a wider range of applications with less cost than cast steelCast mating parts are male/female fit to minimize gasket leaks due to misalignmentInterchangeable springs regardless of size for parts optimizationIntegral and remote pilot optionsIntegral strainer to protect pilot from dirtEasy access to main valve without the need for special tools
