Dosing Value

Dosing Valves for Precise Media Application

Dosing valves enable the controlled application of liquid to highly viscous media – continuously, intermittently, or in pulses, typically in the milligram or microliter range. Common designs include spray valves for surface wetting, jet and pulse valves for contactless spot applications, chamber dosing valves for volumetric microdosing, and valves with full-jet characteristics for linear applications.

In industrial production, in addition to dosing accuracy, reproducibility over high volumes is a key focus. Modern dosing valves support this with configurable control times, integrated sensors for process monitoring, and – depending on the design – the heating of media-carrying components or the recording of system pressure. This allows dosing processes to be reliably integrated into automated process chains and documented with quality assurance.

Depending on the application, dispensing valves are suitable for the point or line application of sealants, adhesives, thermal pastes, solder pastes, oils, greases, release agents, or potting compounds. The selection is based on the media viscosity, the required application form, and the required cycle frequency.

In addition to pneumatically and electrically operated versions, systems with integrated electronics and Ethernet interfaces are increasingly gaining popularity. These allow for centralized parameterization, connection to higher-level automation systems, and real-time monitoring of relevant process variables such as temperature, pressure, or needle stroke. Such valves enable precise yet flexible media application – even with stringent requirements for traceability and process reliability.
