Double Union Diaphragm Valves

We can supply a full range of DVD13 double union diaphragm valves in UPVC plastic from Comer or Onyx, these valves are available to order here on our website in sizes between 1/2" (DN15) and 2" (DN50) nominal bore. All of our UPVC diaphragm valves come with a 10 bar (PN10) pressure rating at ambient temperature, an EPDM diaphragm and an operating temperature range of 0 - 60°C. The DVD13 UPVC diaphragm valve comes with plain solvent welding ends which allow for easy installation in combination with our UPVC solvent cement (available separately).

These are the only type of diaphragm valves we offer here at ValvesTubesFittings.com, the main advantage to this type of valve is their very low head loss and minimal need for maintenance due to having a full flow opening. This type of valve is commonly used in freshwater applications as well as in compressed air and saltwater systems to name but a few.
