VDP150: Positive Displacement Valve

VDP150 Adjustable Positive Displacement Dispensing Valve

The VDP150 is a pneumatically-operated positive displacement valve designed for dispensing constant volume shots up to 0.15 cc of low to medium viscosity material.

Featuring two integral check valves to control the flow of material, the valve is cycled by applying air pressure to the air ports. No fluid pressure is required for low-viscosity materials (less than 5,000 cps) as the material is drawn into the displacement chamber by the plunger.
