New DE Series Diaphragm Valve reaches
new levels of performance.

We started from scratch. And finished with a new design featuring
a welded diaphragm, threadless actuator, formed aluminum body, smaller size,
and a larger inside area to accommodate a bigger diaphragm and piston. Together,
these and other DE Series Diaphragm Valve innovations deliver:

  • Higher flow rates.
  • Up to one million cycles.
  • Easier installation and maintenance.
  • Competitive cost, plus lower total cost of ownership.
  • Standard 1.125 in. (28.57 mm) footprint.

New design. New possibilities. There's much to like about the DE Series Diaphragm Valve.
