VM 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 VM series weir-style diaphragm valves are available in PVC, CPVC, PP, or PVDF, four body styles, and three choices of diaphragms (EPDM, FPM, or PTFE). Able to be mounted in any position, the VM is ideal for either very clean or abrasive slurry applications. A unique and proprietary PTFE diaphragm design, available automation, and multiple accessories make this one of the most advanced and versatile lines in the industry. IPEX diaphragm valves can be pneumatically actuated providing precise control of critical applications.

PRODUCT DETAILS

Body Material: PVC, CPVC, PP, PVDF

Size Range: 1/2" through 4"

Pressure: 150 psi at 73°F depending on the size

Diaphragm: EPDM, Viton® (FPM) or PTFE (EPDM backed)

Control Style: Manual Handwheel

End Connections: Spigot, True Union (Socket), 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.
