Features

No Burning Damage to Solenoid
This feature eliminates the need to stock extra solenoids as spare parts, saving on maintenance costs.
Small Starting and Energizing Current Values
The low current requirements allow for more compact peripheral electrical equipment, enhancing system efficiency.
No Sliding Parts
With no sliding parts, this construction ensures reliable operation without issues such as valve sticking.
Extremely Few Cases of Vacuum Leakage
The excellent vacuum response ensures superior pick-up by the vacuum pad, making it easy to install a compact vacuum pump.
Dust-Resistant
This construction can be used with an ordinary air filter, even in dusty locations, providing flexibility for various environments.
Can Be Used Without Lubrication
The equipment operates optimally even without lubrication, which is ideal for environments where oil is not feasible.
Compact and Lightweight
This system is easy to mount in any location, making it suitable for both compact installations and control panel setups.
