DV Series Diaphragm Valve

Diaphragm valves are the perfect solution when precise flow throttling is required.

  • Precise flow control
  • High cycle life
  • Excellent for abrasive slurries

 

The DV is a rugged industrial product ideal for throttling or use in abrasive slurry lines. The raising position indicator also functions as an adjustable travel stop. This feature can be used to avoid over-compression of the EPDM or PTFE diaphragm, or as a travel limiter allowing different settings for the "closed" position. The molded flanged body eliminates potentially leaky joints while featuring end-to-end dimensions identical to most plastic lined metal diaphragm valves, allowing for direct replacement.

IPEX diaphragm valves can be pneumatically actuated providing precise control of critical applications.

PRODUCT DETAILS

Body Material: PVC

Size Range: 1/2" through 6"

Pressure: 150 psi

Diaphragm: EPDM or Teflon® (PTFE)

End Connections: Flanged (ANSI 150)

These valves are widely used in high purity applications because their design prevents friction and subsequent particle creation when cycling. Many body and diaphragm material options are available as well as simple pneumatic actuation.

 

Automation & Accessories

IPEX diaphragm valves can be pneumatically actuated providing precise control of critical applications. The normally closed (fail close), normally open (fail open), and double acting VM valves make up of one of the most extensive ranges in the industry. The actuated CM provides a compact solution to automated needs while the DM employs an efficient direct acting design. All pneumatic diaphragm valves can be outfitted with many options and accessories such as: stroke limiters, optical and electric position indicators, electro-pneumatic positioners, pilot valves, and various combinations thereof.
