Single Tube screw valve Eccentric Screw Rotor Dispensing Valve
Machine Introduction
Single-tube screw valves are precision volumetric metering and conveying devices, suitable for a wide range of high-precision quantitative conveying applications. The single-component screw pump features a spiral structure design, with a self-sealing arrangement between the screw and stator. As the screw rotates within the stator cavity, it achieves a quantitative conveying function. This conveying process avoids exerting a shear effect on the medium, thereby preserving its characteristics. Additionally, the pump can be reversed via the motor to facilitate suction and easy adhesive breaking, providing an effective solution to the issues of dripping and pulling during the dispensing process.
Working Principle
The volumetric metering and filling system of the single-tube screw valve operates on the infinite piston principle, featuring a hermetic design between the rotor and stator. The rotor rotates within the stator core to achieve precise quantitative delivery of colloids and fluids with varying viscosities, ranging from low to high.
At the heart of each application lies the volumetric delivery metering pumps, which guarantee pressure stability and linear pump characteristics. These pumps establish a predictable relationship between pump speed, time, and flow rate, enabling consistent material metering either through time control or pump rotational speed.
Whether dealing with low or high viscosity fluids, abrasion-resistant materials, or highly filled fluids that are sensitive to structural changes, dispensing accuracy remains unaffected by viscosity.

Product Features and Advantages
High glue dispensing precision
Adopting servo motor drive and eccentric screw rod feeding, so that the glue adhesive can be continuously and stably output.
Wide range of glue viscosities and spitting volumes
Adjustment of motor speed and gas pressure can be used to dispense different glue viscosities and quickly change the amount of glue spit.
No dripping and pulling of glue
The motor reverses and sucks back, easily solving the problem of dripping and pulling of glue.
Great adaptability of stator
The stator is resistant to medium corrosion and has a long service life, which greatly reduces the user's overall cost of ownership.
Volumetric metering
True volumetric conveying, the flow rate is not affected by pressure changes.
High output pressure
Single pump output pressure ≥ 20bar
