Precision Screw Valve KSV1000-R Hot Melt Dispensing Valve for Dispensing Middle Frame
The concentric screw valve is a high-precision dispensing solution ideal for applying hot melt adhesives in smartphone mid-frame assembly. Its concentric structure ensures stable and uniform glue flow, essential for bonding components like the screen, battery bracket, and rear housing. By using a servo or stepper motor to drive the screw, the valve delivers continuous, pulse-free adhesive output, even under high viscosity and temperature conditions. It supports accurate start-stop control, clean cut-off, and minimal stringing, which improves product appearance and yield. The concentric screw valve is widely used in automated production lines where consistent glue volume, clean dispensing, and high-speed performance are critical.
Core Advantages
1. Concentric structure, more stable glue output
2. Suitable for high viscosity fluids: such as hot melt glue, PUR glue, thermal conductive glue, structural glue and other high viscosity colloids;
3. Support heating, suitable for hot melt glue process: 30CC glue barrel heating module
4. High repeatability and high glue consistency
5. Clean glue cut-off without drawing
Main appliaction
Bonding or sealing of mobile phone middle frame with screen, back cover, battery holder and other components.

FAQ
Q1: What is a concentric screw valve and how does it work?
A1: A concentric screw valve uses a motor-driven screw mechanism to dispense fluid with high precision. Its concentric (coaxial) design ensures that the screw and sleeve rotate in perfect alignment, delivering consistent flow of high-viscosity materials like hot melt or PUR adhesive.
Q2: What types of fluids are suitable for this valve?
A2: The valve is ideal for high-viscosity materials, including PUR hot melt adhesives, epoxy, thermal paste, and silicone sealants. It can also be integrated with heating modules for temperature-sensitive fluids.
Q3: What are the advantages of using a concentric screw valve compared to a traditional pneumatic valve?
A3: It offers much higher precision, consistent flow control, and cleaner cutoff without stringing. Unlike pneumatic valves, it is not affected by fluid viscosity or air pressure fluctuations, making it ideal for automated, high-precision dispensing.
