Needle valve for low to medium viscosity materials

Description
The needle valve DV-5425 was especially developed for dispensing of low to medium viscosity materials. The DV-5425 needle valve enables control of material from extremely small individual shots to continuous beads. The needle dispensing valve is pneumatically controlled. The slim design allows for installation in automated lines and a high packing density.

Functionality
The valve is closed in the idle state. The opening gap is adjustable on the valve. The valve is opened with the control air. The valve needle moves up out of the seat and the material can then flow through the material input to the material output. Optionally, auxiliary air can be used for faster closure. Otherwise, the valve closes using spring force.

Dispensing materials
Adhesives, UV adhesives, Alcohol/Methanol, Oils/Greases/Lubricants
