Since P K Saunders invented the original diaphragm valve in 1928 and founded Saunders Valve Co. five years later, Saunders® has led the way in providing solutions in industries where resistance to corrosion, abrasion, contamination, and trouble-free operation are imperative. Simplicity in design coupled with over 75 years of cutting edge innovation has resulted in the Saunders® diaphragm valve’s ability to handle a wider range of fluids than any other valve type. Our core competencies in rubber and polymer technology uniquely position us to truly manage 'The Science Inside' the valve. Our major manufacturing facilities around the world including:

  • Cwmbran (U.K.)
  • Satara (India)
  • Conroe (US, Texas)
  • Cincinnati (US, Ohio)

We manufacture our products to international standards; our range encompasses a complete line of manual and linear actuated diaphragm valves, both weir and straight through type, aseptic diaphragm valves and blocks solutions, non-return check valves and ball valves.
