Air Diaphragm Valve V351 series

The dispenser valves, Air Diaphragm Valves V351 series are designed to dispense only low viscosity materials. The mechanism of this valve is excellent in preventing material from dripping, leaking or accumulating at the valve needle tip. As there is no “suck back” force used, air is not suck back into the valve, and thus fluid can be dispensed smoothly without any slurry or traces left at the needle tip.
