KOGANEI CORPORATION
Koganei Piloted Vacuum Valves Single Pilot Type
Manufacturer: KOGANEI CORPORATION
Features
No burning damage to the solenoid eliminates the need for stocking extra solenoids as spare parts, reducing maintenance costs and increasing system reliability.
With minimal current requirements, the system enables the use of more compact electrical components. As a result, it enhances efficiency and saves valuable space.
The absence of sliding parts prevents valve sticking, ensuring smoother and more reliable operation.
The superior vacuum response facilitates excellent pick-up by a vacuum pad. Consequently, it allows easy installation of a compact vacuum pump for improved performance.
The system is designed to work seamlessly with an ordinary air filter, making it effective in dusty environments and ensuring long-lasting performance.
This feature is perfect for environments where lubrication isn’t possible. As a result, the equipment continues to operate optimally without the need for oil.
Its design facilitates easy mounting to control panels, while also supporting various mounting directions. This makes it suitable for space-constrained applications and versatile installations.
