High Speed PUR Piezo Valve Wear Resistant Material With Luer Connector For Hot Melt Dispensing

High Speed Operation PUR Piezo Valve Wear Resistant Material With Luer Connector Hot Melt PUR Adhesive Piezo Jet Dispensing Valve For Electronic Assembly

Product Introduction

The PUR Piezo Valve is a high‑speed, high‑precision non‑contact dispensing valve specially optimized for PUR hot melt adhesive applications. Adopting advanced piezoelectric driving technology, this industrial piezo valve delivers ultra‑fast response and consistent micro‑volume dispensing performance. Different from traditional pneumatic dispensing valves, the PUR piezo jet valve realizes jet dispensing without Z‑axis contact movement, effectively avoiding workpiece scratching and glue residue deviation. Equipped with wear‑resistant structural materials and professional heating modules, it perfectly adapts to the melting and dispensing characteristics of PUR hot melt glue, ensuring stable glue output and excellent molding effect in long‑term continuous production. It is a core fluid control component for high‑end automated dispensing 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.

PUR Piezo Valves:

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.

Piezo Valve Controller

1. The touch screen controls the piezoelectric injection valve and dispensing system, supports 485 communication, powerful, safe and reliable.
2. The touch screen adopts graphic control mode, the components of dispensing system and the control display function are displayed graphically, which is concise and intuitive.
3. Nozzle heating device:The nozzle is required to be heated to a suitable temperature before dispensing. The heating device adopts one-stage heating mode.
4. Heating at the nozzle maintains the constant temperature of the gel to meet the best performance of the gel. The best performance of the colloid.

Nozzle and drum heating

1. The nozzles need to be heated to a suitable temperature before glue dispensing. The heating device adopts a two-stage heating method.
2. Heating at the barrel and nozzle maintains the constant temperature of the glue to meet the optimum performance of the glue.
