752HF High Flow Diaphragm Valves

The 752HF Series high flow diaphragm valve provides precise, drip-free dispensing of UV-cure resins and similar fluids used in the media manufacturing of DVDs, Blu-Ray DVDs, and CDs.

Designed for smooth, unrestricted material flow, the 752HF reduces turbulence and prevents micro-bubbles from forming. This creates a more consistent, higher-quality end product with fewer rejects.

The compact and lightweight 752HF-SS provides controlled, bubble-free dispensing for bonding and lacquer coatings. It features a 303 stainless steel fluid body, tamper-resistant stroke control adjustment, and a low-maintenance design. The 752HF-A is the same as the 752HF-SS, but features an acetal copolymer fluid body.


  • High-flow capability for thicker UV-cure coatings
  • Valve open time as short as 15 milliseconds
  • Positive shutoff, no seals
  • Cycle rate exceeds 500 cycles per minute
  • Compact and lightweight

Compatible Fluids

  • UV-cure adhesives
  • Resins
  • UV coatings

The complete system includes the 752HF dispense valve, ValveMate™ 8000 controller, fluid reservoir, and dispense tip. For even faster throughput, integrate with an EFD automated dispensing system.

Also available, the 702 Series mini-diaphragm valve features a design that’s 60% smaller and 70% lighter than typical dispense valves. For applications where space is tight, select the 702 Series.
