Koganei Compact 2-Port And 3-Port Valves For Chemical Solutions PVS Series

Manufacturer: KOGANEI CORPORATION

Features

This design uses indirect acting 2 and 3 port solenoid valves with a 1.5 millimeter orifice diameter and a 12 millimeter valve width, and it supports reliable handling of chemical solutions. As a result, the system fits perfectly in dispensing processes for analyzers. Moreover, the valve structure considers smooth flow inside the valve chamber, which improves stability and accuracy during operation.

In addition, the indirect acting design prevents heat transfer to the media, so it helps maintain consistent chemical properties. Furthermore, the manifold structure allows free combination, and users can mount up to twenty valves to create flexible and scalable systems. Consequently, this configuration delivers efficient layout design, precise dispensing control, and high adaptability across analytical and chemical processing applications.
