DOPAG Adhesives Needle dispensing valves

Listing ID #4661862

Clean, precise, and reliable

Dispensing valves are used for processing low to high viscosity media. Adjusting the position of the needle in relation to its seat can control the size of the outlet orifice, thus giving control of the flow rate of the material. When fully closed, the needle seals against its seat and is sealed at the throat by an adjustable packing set. The valve is constructed in two separate parts. This separation of the fluid section from the actuating air section means that it is not possible for any leaking material to flow into the actuating air cylinder, which might otherwise cause a malfunction of the valve. Material passageways can be quickly flushed out if necessary (Internal diameter: 1 - 16).
