The screw dispensing valve is a screw valve metering dispensing head, which is mainly used for metering hot melt adhesives and thermal conductive adhesives with medium and high viscosity, providing high flexibility for variable glue volume and glue coating on different workpieces. Its core components, the rotor and stator, form a completely sealed metering chamber to achieve continuous metering dispensing, which is not affected by fluid viscosity. Optional high-flow screw dispensing valves, micro screw dispensing valves, and dual-liquid screw dispensing valves.
