Dispensing Valve - Your Solution from marco systems
High-precision dispensing valves
Dispensing valves are special valves designed to deliver or dispense liquids or other viscous substances in precisely defined quantities. These valves are primarily used in industrial processes where precision is critical. Various valve types are available on the market, controlled mechanically, pneumatically, hydraulically, or electrically, depending on the model.
marco systems offers a wide range of precision valves, all based on marco systems proprietary piezo technology. Our product range includes advanced dispensing valves, valve inserts, and custom dispensing heads that work either with or without direct contact. Integrated into our gantry systems, or portal robots, they excel in flexibility and precision.
Our customers benefit from:
- increased process reliability,
- improved quality assurance and
- highly cost-efficient manufacturing processes.
Innovative and sustainable: What makes our dosing solutions stand out?
marco systems’ dispensing systems are based on the latest technological developments, including the in-house developed piezo technology called TorqueBlock drive, ensuring consistent and reproducible dispensing accuracy. Additionally, the valves from the SJet series feature an actively regulated stroke control ("StrokeControl"). With this regulation, we can define how far, fast, and strongly the valve plunger is moved. Deviations are automatically compensated, and feedback is sent to the control computer in real time. This ensures consistently stable liquid dispensing for both low- andhigh-viscosity liquids. The result? Superior control and flexibility compared to competitors.
Another highlight is the contactless dispensing technology (jetting), designed specifically for industries requiring high precision without direct contact with the substrate. Contactless dispensing is also very fast, making it an efficient method for increasing production capacity.
Contactless dispensing techniques include:

DotJet dispensing: Precise application of dots or drops, ideal for applications requiring small and exact amounts of material. The dispensed quantity is significantly influenced by the geometry of our sealing seats, which can be individually customized.

StringJet dispensing: This method has the same precision characteristics as the DotJet. However, it is particularly suitable for the contactless dispensing of larger quantities of material.

Spraying and coating: A technique where liquids are sprayed in fine doses onto surfaces, ideal for cavities and conformal coating of large or sensitive areas, such as in display manufacturing.
In addition to contactless dispensing techniques, our dispensing valves also support contact-based fluid dispensing:

NeedleDot dispensing is a precise technique where a needle applies tiny fluid dots, ideal for applications requiring maximum accuracy and minimal material amounts.

NeedleLine dispensing is a needle-based process that applies continuous fluid lines, perfectly suited for uniform and controlled applications along complex contours.

StepDot dosing: An advancement of the NeedleDot and NeedleLine techniques. This dispensing head operates autonomously with independent movement across all spatial axes. Ideal for the precise dispensing of solder paste or the application of dams in the dam-and-fill process.
All our dispensing valves and dispensing heads enable the controlled application of even the smallest quantities, under 1 nL, of adhesives, solder pastes, lubricants, coatings, acrylics, silicones, or 2-component media and more, optimizing production processes and minimizing material waste. This conserves resources and enables sustainable production. At the same time, the modern control technologies of the systems allow energy savings.
An additional advantage: marco systems dispensing solutions can be directly integrated into our own gantry systems (portal robots) if required. This allows our customers to rely on a single, efficient solution instead of coordinating with multiple suppliers. The use of marco systems gantry systems helps companies efficiently increase their production capacity while ensuring the quality of their products.
Industry solutions and applications
marco systems offers dispensing solutions for a wide range of industries. In medical technology, our dispensing valves are used in the production of precision parts that are critical for drug administration. For example, marco systems supplies dispensing heads for the production of nasal sprays and auto-injectors used for precise drug delivery, such as insulin or adrenaline pens. Our high-tech dispensing systems ensure the reliability and quality of the products. In the electronics industry, especially in semiconductor manufacturing or display production, our industrial valves play a crucial role as tiny amounts of solder pastes, fluxes, or silicones must be applied precisely.
In display manufactoring, where microdispensing is used to encapsulate mini LEDs with Liquid Rubber Silicone (LRS), we are a solution partner for major brands. This is where the strength of our systems shines: maximum precision and repeatability ensure the protection and performance of the products.
In the food industry, our dispensing systems contribute to improving packaging processes by optimizing the dispensing of components such as silicone rings or pressure relief valves for packaging.
