Koganei RZ Series Pressure Regulators

The Koganei RZ Series are next-generation pressure regulators built for high flow performance and compact installation in modern pneumatic systems. They use a direct-acting and internal pilot pressure regulation system, which gives you better flow characteristics and lets units be installed side by side without needing extra space between them.

The compact body includes a clearly visible pressure setting range window, making it easy to check and adjust pressure at a glance. Built-in pressure gauge options are available if you need local pressure display. A removable adjustment knob adds tamper resistance for added safety in industrial environments. Sizes 40 and 50 support modular air preparation assemblies, so you can combine them with filters and lubricators to build a complete air preparation unit.
