36 DIAPHRAGM VALVES Specifications Size: 77.3 mm length x 28.6 mm diameter (3.04" x 1.13") Weight (less fittings): 752HF-A: 81 g (2.85 oz) 752HF-SS: 123 g (4.30 oz) Actuating air pressure required: 70-90 psi (4.8-6.2 bar) Maximum fluid pressure: 70 psi (4.8 bar) Fluid inlet thread: 1/8-27 NPT Mounting: (1) M5 x 0.8 Cycle rate: Exceeds 500 per minute Air cylinder body: Aluminum, hard-coat anodized Fluid body: 752HF-A: Acetal copolymer 752HF-SS: 303 stainless steel Piston: 303 stainless steel Diaphragm: UHMW* polyethylene, FDA approved Tip retaining nut: Aluminum All stainless steel parts are passivated. *Ultra High Molecular Weight polyethylene For use with: UV-cure Adhesives Resins UV Coatings Air Cylinder Body Diaphragm Tamper-resist Stroke Adjustment Piston Fluid Body Tip Retaining Nut The ValveMate 8000 controller allows for easy on-the-fly deposit control of the 752HF Series valves. Refer to page 52. 7014139 (752HF-A Valve) Air cylinder body assembly and tamper-resist stroke reference knob are hard-coat anodized aluminum. Acetal copolymer fluid body and UHMW* diaphragm. Includes fluid inlet fittings #7021499 and #7007038. 7014315 (752HF-SS Valve) Same as 752HF-A except fluid body is passivated 303 stainless steel. *UHMW—Ultra High Molecular Weight polyethylene Piston Spring Fluid Inlet 1/8 NPT High Flow Diaphragm Valve 752HF Series The 752HF valve system is specifically designed for precise dispensing of UV-cure resins and similar fluids used in media manufacturing of Blu-Ray DVDs, DVDs and CDs. Unrestricted material flow reduces turbulence and the formation of micro bubbles. Features and Benefits • High-flow capability for thicker UV-cure coatings • Valve open time as short as 15 milliseconds • Positive shutoff, no seals • Compact and lightweight www.nordsonefd.com info@nordsonefd.com USA & Canada 800-556-3484 Europe +44 (0) 1582 666334 Asia +86 (21) 3866 9006
