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.
Overview
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.
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.
