Undoubtedly, the jetting valve is a novel tech that has revolutionised the fluid dispensing industry. The ground-breaking innovation has opened up an entirely new level of accuracy, paired with exceptional speed and precision in the field. Thanks to it, its users can dispense fluids faster and more accurately than ever. Explore how it changed the game in fluid dispensing, from the first jetting valve designs to the most modern models.
Understanding Traditional Fluid Dispensing
Arguably, fluid dispensing has a long history before exploring jetting valves. For a long time, manual syringe and contact dispensing were the top options to accurately dispense liquids across various sectors.
Manual syringe dispensing had someone in charge of using a syringe to control the release of the liquid. While there was some control, accuracy and precision were limited. It needed someone with talent and stability to ensure identical results.
On the other hand, contact dispensing presented a more accurate and consistent option for fluid dispensing systems. It turned out particularly efficient in medicine and science where exigent volume dosing was necessary. Such systems use a specialised dispenser that makes contact with the fluid surface to remove air bubbles and impurities, making a crucial impact in applications with micro variations in volume.
Despite having certain merits, the two methods were deficient in many areas. Some disadvantages included slow speed, human mistakes, and lack of precision and uniformity required in some industries.
The Emergence of Jetting Valves in the Industry
The introduction of jetting valves revolutionised the fluid dispensing industry. It was an inconceivable breakthrough in precision and accuracy. Seeking quicker and more precise fluid dispensing sparked the development of this technology, now widely used in multiple industries.
Of course, traditional approaches provided adequate results. Still, they lacked speed, precision, and reliability. It necessitated skilled personnel, took more time, and was prone to human error. That’s why companies needing high accuracy and consistency had to search for better solutions.
The jetting valve emerged as the answer to these issues with its cutting-edge technology and microprocessor-controlled algorithms. By creating well-regulated pulses of liquid, it enabled faster, more precise, and consistent dispensing of fluids. This mechanism revolutionised the field, unleashing countless new opportunities and increasing productivity. Moreover, it opened up new possibilities that increased the overall productivity in every industry.
Undoubtedly, the emergence of jetting valves paved the way for advancements in electronics manufacturing, automotive assembly, pharmaceuticals, and many more. From micro dot dispensing to high-speed line dispensing, they became the backbone of fluid dispensing processes across various industries.

Types of Jetting Valves Available in the Market Today
Selecting the best jetting valve for your liquid delivery requirements necessitates careful consideration of the types of valves accessible. Each one supplies exclusive qualities and benefits to locate the perfect valve for your project. Here are some popular types of jetting valves you may find:
Pneumatic Jetting Valves
Pneumatic Jetting Valves boast fast, precise liquid release using compressed air. Ideal for rapid operations, these valves usually serve in the automotive and electronics sectors. Furthermore, they have created a positive reputation for their decent performance.
Piezoelectric Jetting Valves
Piezoelectric jetting valves utilise piezoelectric crystals, which expand or contract when subjected to an electric field. As the volume of the valve changes, it generates the necessary pressure for fluid dispensing. These valves offer excellent accuracy and repeatability, making them suitable for applications that require extremely precise fluid dispensing, such as microdot deposition and fine-line dispensing in the electronics industry.
Ultrasonic Valves
As the name suggests, ultrasonic jetting valves use high-frequency sound waves as a fluid dispensing technique. Using vibration from the sound waves, the valves open and close, allowing the dispensing of small volumes of fluid with high accuracy. Some common applications for this contactless jetting valve type are semiconductor manufacturing and biomedical research.
Magnetic Valves
Magnetic jetting valves use a magnetic field, which applies to a ferromagnetic material in the valve. The pressure causes the valve to open or close, making it a a simple yet efficient contactless dispensing solution for automated assembly systems and laboratory equipment.
Optical Jetting Valves
Optical valves use the power of light and light reflection to detect and monitor the presence of fluid and control its flow. The technique involves a sensor, which “tells” the valve when to open or close based on the amount of reflected light. The mechanism of optical valves makes them suitable for fuel sensors and industrial automation systems.
Choosing the Right Jetting Valve for Your Dispensing Needs
Selecting the correct jetting valve is pivotal for reaching excellent outcomes and satisfying your liquid dispensing desires. As many choices are accessible, deciding which valve will fulfil your purpose can be challenging. To help make the decision, here are several things to consider when selecting a jetting valve:
Fluid Viscosity
Depending on the fluid type, certain valves may handle different viscosity better. Typically, low-viscosity fluids require a certain kind of valve, while high-viscosity liquids demand another. In this regard, selecting a valve that can efficiently handle the fluid's viscosity range is essential.
Dispense Volume
Evaluate the required dispense volume for your application. Some valves are designed for micro dot dispensing with small volumes, while others can dispense larger volumes. Choose a valve that can accommodate the dispense volume you need to ensure accurate and consistent results.
Dispense Speed
Consider the desired dispense speed for your application. Typically, some valves are suitable for high-speed dispensing, making them perfect for applications with rapid production cycles. Other valves may offer slower dispensing speeds, which can be advantageous for precise and controlled dispensing.
Fluid Compatibility
Ensure that the jetting valve you choose is compatible with the specific type of fluid you will be dispensing. Different valves may be better suited for adhesives, solder pastes, or other types of liquids. Check the valve specifications to verify its compatibility with your desired fluid.
Application Requirements
Consider the unique requirements of your application. Some valves may offer additional features, like dispensing multiple fluids simultaneously or adjusting the dispensing pattern. Evaluate your application needs and select a valve that can meet those requirements.
Manufacturer Reputation
Research the reputation and track record of the valve manufacturer. Look for a reputable manufacturer that is known for producing high-quality and reliable jetting valves. Reading customer reviews and testimonials can tell you a lot about the performance and durability of different valves.
6 Maintenance Tips to Ensure Optimal Performance
Maintaining your jetting valve is crucial for ensuring optimal performance and longevity. By following these maintenance tips, you can keep your valve in top condition and avoid any disruptions in your fluid dispensing process.
