What are the advantages and applications of a metering valve?
The metering valve is an indispensable tool in the hands of modern installers. It is distinguished by its compact, simple, reliable construction, allowing for versatile use in industry and long-term, trouble-free use. Some models are additionally equipped with a cleanout for quick cleaning.
The metering valve, as the name suggests, is used for precise metering of: water, adhesives, sealants, lubricants, pastes and many other substances. By using the metering valve, you can optimize the consumption of liquids and various materials and deliver precisely measured amounts, which:
- translates into real financial benefits,
- allows you to take better care of the natural environment,
- prevents mistakes and waste of resources,
- ensures repeatability of dosing.
Due to their relatively low price, dosing valves are an inseparable part of production lines – regardless of the type of manufactured products. They are also part of the construction of professional construction machines, e.g. blasters (sandblasters). The role of the valve in such a machine is to precisely dose the abrasive. This inconspicuous accessory allows for a significant increase in cleaning efficiency with lower air consumption.
Depending on the properties of the substance being dosed, the environmental conditions at the installation site and the assumed intensity of use, the appropriate type of dosing valve should be selected. This is the basis for efficient operation and optimally long service life of the device. Among others, flow, volume and pressure valves are available on the market. On the other hand, due to the type of built-in control system, mechanical, pneumatic and electronic valves can be distinguished.
