Koganei Air-Piloted Valves 375A, 501A, 750A, 1000A, 1250A Series

Manufacturer: KOGANEI CORPORATION
Features
This system requires only air piping, so no electrical wiring is needed. As a result, there is no risk of electrical shocks or current leakage. Additionally, without electricity, expensive equipment for explosion protection or noise reduction is unnecessary. The simple construction ensures durability, and the use of harmless compressed air makes installation and maintenance easier, even in areas without power. Furthermore, the system retains memory, allowing continued operation for several dozen minutes during power outages.
The solenoid valve, designed for assured operation, uses a poppet and diaphragm construction. This ensures quick switching and maintains reliable valve seat performance. The design prevents breakdowns, as it eliminates issues like galling or sticking, even when small debris enters. It can operate without lubrication, minimizing maintenance and prolonging system life.
This unit tolerates frequent operations with its impact-absorbing synthetic rubber components, making it perfect for high-frequency use. Moreover, its compact aluminum alloy body ensures both durability and easy installation. The valve can be mounted in any direction, providing flexibility for various applications.
Ultimately, this system is the ideal air valve for master or pilot valves, offering reliable and efficient pneumatic control. It also reduces operational costs.
