VMS400 The VMS400 is a mini-spool type pneumatic valve designed for dispensing low viscosity to high viscosity materials. When air pressure is applied to the air inlet of the VMS400 valve, the spool will be forced forward and fluid will be dispensed. The VMS400 valve has a suck-back effect that eliminates lumping at the end of the needle after dispensing. Turning the adjustment control at the top of the valve regulates the amount of suck-back. Shot size and flow rate are controlled by the tip size, fluid pressure and the duration that the valve is open. Features • High pressure fluid input up to 700psi • Suitable for high viscosity fluids • Adjustable suck-back effect Sales & Support Fisnar Global Headquarters Tel: 1 (973) 646-5044 www.fisnar.com Fisnar Asia Asia Headquarters Tel: 852-2389-2827 www.fisnareurope.co.uk Fisnar Europe European Headquarters Tel: +00 44 (0) 1355 577 222 www.fisnareurope.co.uk Operating air pressure: Material delivery pressure: Flow rate: Minimum shot size: Driving part materials Body, Piston: Spool: Cap: Wetted part materials Chamber, Cap: Seal: Connecting ports Air inlet / outlet: Material inlet / outlet: Weight:
