34 DIAPHRAGM VALVES Diaphragm Valve 752V Series General-purpose valve is ideal for dispensing controlled amounts of most low- to medium-viscosity fluids. Wetted components are machined from inert UHMW (Ultra High Molecular Weight) polyethylene, making the 752 Series ideal for use with cyanoacrylates, anaerobic threadlockers and other reactive fluids. Features and Benefits • Compact size and weight • Adjustable fluid flow control • Positive shutoff, no seals • Low-maintenance design For use with: Activators Anaerobics Cyanoacrylates Fluxes Solvents UV-cure & Light-cure Adhesives Specifications 752V-UHSS Size: 80.7 mm length x 26.9 mm diameter (3.18" x 1.06") Weight: 173.6 g (6.1 oz) 752V-SS Size: 80.7 mm length x 26.9 mm diameter (3.18" x 1.06") Weight: 181.4 g (6.4 oz) 752V-DVD Size: 76.3 mm length x 26.9 mm diameter (3.00" x 1.06") Weight: 172.9 g (6.1 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 NPT female Fluid outlet thread: 1/4-28 UNF Mounting: (1) 10-32 UNF tapped hole Cycle rate: Exceeds 500 per minute Air cylinder body: 752V-UHSS: 303 stainless steel 752V-SS: 303 stainless steel 752V-DVD: Aluminum, hard-coat anodized Fluid body: UHMW* polyethylene, FDA approved Fluid body options: Acetal, 303 stainless steel, PTFE Piston and piston rod: 303 stainless steel Tip adapter: Polypropylene Diaphragm: UHMW* polyethylene, FDA approved Diaphragm option: PTFE Wetted parts: Fluid body, diaphragm, tip adapter All stainless steel parts are passivated. *Ultra High Molecular Weight polyethylene 7021428 (752V-UHSS Valve) Air cylinder body assembly is passivated 303 stainless steel.

Get faster response time without the risk of process variations due to fluctuating plant air supply or varying valve air hose lengths. • High-speed cycle capability. Cycle rates exceed 60-80Hz • Actuation speed as low as 5-6 milliseconds • Smaller deposit size capability due to faster valve actuation speed • Improves process variation for better dot-to-dot consistency BackPack is available preinstalled on new valves, or can be ordered separately (#7015581) to retrofit existing valves.
