High Speed PUR Piezo Jetting Valve Heat Resistant With Luer Connector For PUR Hot Melt Dispensing

High Speed Operation PUR Piezo Jetting Valve Heat Resistant Material With Luer Connector Non Contact Hot Melt Glue Dispensing Valve For Electronic Assembly

In advanced manufacturing, applying high-viscosity adhesives like PUR (Polyurethane Reactive) hot melt requires equipment that balances extreme precision with robust performance. Our PUR Piezo Valve is a state-of-the-art, non-contact jetting solution specifically engineered to handle the unique challenges of reactive hot melts. Utilizing dual-piezo actuation technology, this valve delivers superior jetting force and ultra-fast response times, ensuring clean glue breaks and accurate micro-dispensing without the smearing associated with traditional contact methods. It is the ultimate upgrade for high aspect ratio processes and automated smart production lines.

1. The PUR Piezo valve consists of barrel heating module, pressurized cap module, nozzle heating module, runner module, valve body module and heat dissipation module.
2. The barrel heating module carries the barrel and a section of heating, temperature controllable, to complete the initial heating of the gel.
3. The pressurized cap module seals and pressurizes the barrel and controls the output pressure through the controller.
4. The heat dissipation module dissipates the heat and reduces the noise of the valve body.
5. Piezo-electric injection valve adopts modular design, the part in contact with the gel is designed as runner module, and the part not in contact with the gel is designed as valve body module.
6. In different applications, the runner module can be replaced to meet the dispensing needs.
7. Nozzle diameter (from 0.03MM to 0.80MM). Nozzles are available in flat jet, needle, and extension types.
8. Runner modules need to be cleaned regularly in an ultrasonic cleaner. Seals should not be immersed in organic solvents. Special tools are required to clean the nozzles to prevent damage to the nozzles.

How it works:
PUR piezo valves utilize the piezoelectric effect, where an applied electric field causes a material (usually ceramic) to deform.

This deformation is used to open and close the valve, enabling precise control of the flow of fluids or gases.

Unidirectional flow:
PUR piezo valves are designed to allow flow in only one direction, making them suitable for applications that require tight flow control.

The unidirectional feature prevents backflow and ensures accurate metering of fluids or gases.

High-speed operation:
Piezo-actuated valves enable extremely fast response times, measured in milliseconds or even microseconds.

This high-speed operation enables precise timing and control of fluid or gas pulses, enabling applications that require rapid on/off cycles.

High precision:
PUR piezo valves offer excellent repeatability and accuracy in flow control, providing consistent, repeatable flow rates.

The precise control of piezo actuation enables metering and dosing applications that require high precision.

Compact design:
PUR piezo valves are typically compact and lightweight compared to traditional solenoid valves.

This makes them suitable for space-constrained applications such as portable devices or miniaturized systems.

Reliability and Lifespan:
Piezoelectrically actuated valves are known for their reliability and long service life as they have no mechanical wearing parts.
The absence of sliding seals and non-contact actuation contribute to the durability and long service life of the valve.
