VMS400 Mini Spool Dispensing Valve

VMS400 Mini Spool Dispensing Valve

The VMS400 is a mini-spool valve designed for dispensing small volumes of medium to high viscosity materials. When air pressure is applied to the air inlet of the valve, the spool will be forced forward and fluid will be dispensed.

Shot size and flow rate are controlled by the tip size, fluid pressure, and the duration that the valve is open.
