Koganei Compact 2- And 3-Port Media Isolation PVR Series

Manufacturer: KOGANEI CORPORATION

Features

This lineup adds FKM specifications that suit cleaning processes for medical analysis, and the PVR20 model specifically supports these demanding applications. As a result, users gain greater reliability during frequent cleaning cycles. Moreover, the compact valve design delivers a large flow rate, which improves efficiency in medical analysis systems.

In addition, the lineup includes the PVR16 with a 1.6 millimeter orifice and the PVR20 with a 2.0 millimeter orifice, so users can select the optimal size for their process. Furthermore, the rocker type structure minimizes changes to internal volume, which enhances dispensing stability and accuracy. At the same time, the wetted area remains metal free, and this feature significantly improves corrosion resistance.

Additionally, a power saving circuit comes standard, so the system achieves low power consumption without sacrificing performance. As a result, long term operation becomes more economical. Moreover, the design supports a long service life of up to ten million cycles under Koganei testing conditions, which increases overall reliability.

Finally, the lineup offers both solenoid valve types and air operated types for the PVR16 model, which expands application flexibility. In addition, the PVR20 model supports an operating pressure of up to 0.3 megapascals, or 44 psi, so it delivers stable performance across a wide range of medical analysis environments.
