DISPENSING NEEDLE VALVE DA 400 EV DAV TECH SRL Via Ravizza, 30 36075 Montecchio Maggiore (VI) - ITALY Tel. 0039 0444 574510 Fax 0039 0444 574324 [email protected] www.davtech.it The needle valve DA 400 EV is designed to dispense in a controlled, precise and repeatable way, fluids with medium to high viscosity. The valve has the feature to be customized with nozzles with various shapes and sizes, availables in the catalog. The solenoid valve, mounted directly on board, allows high precision in the deposition, and makes it ideal to be integrated on automated systems, such robots, SCARA and Cartesian arms. FIELDS OF APPLICATION: > Silicone dispensing > Grease dispensing > Resin dispensing > Medium to high viscosity fluids dispensing Model Operation mode Weight Max fluid pressure Actuating air pressure Air inlet thread Fluid inlet thread Outlet Thread Speed Adjusting the passage Used Materials Fluids to be used FEATURES: > Fine adjustment of the flow rate (optional) > Solenoid Valve 5/2 mounted on board to have an instantaneous start / stop > Easy maintenance and cleaning of the valve > TCT needle and nozzle in stainless steel for long life > Surface coating with Teflon to make the valve easy to clean the inside and improve the flow of the highest viscosity fluids > Divorced construction, the pneumatic part is separated from the passage of the fluid. DA 400 EV Double Acting 310 g 80 bar 6 - 7 bar M5 1/8 BSP Threaded nozzles, luer lock thread, steel nozzles of various shapes and sizes Up to 300 cycles / min With micrometric screw or with screw and nut Stainless steel, TCT, nickel plated brass and Teflon Silicones, liquid gaskets, greases, resins, various medium-high viscosity

NOZZLES FOR DA 400 EV DISPENSING VALVE The valve DA 400 EV presents a very high number of nozzles available as standard. Nozzles with thread 1/8 BSP male, luer lock, nozzles complete with various shapes and diameters from 0.3 to 1.5 mm. If necessary, we can design and create multi-point terminals, with radial outlets, inclined etc. DRIVE VALVE DA 400 EV The valve has a 5/2 solenoid valve mounted directly on board, and it is therefore sufficient to feed the power supply (24V) to the solenoid (which is always kept fed pneumatically to 6-7 bar) for controlling the dispensing.
