Pressure-type vacuum breaker "VD-7N model"
Can be used indoors! Suitable for preventing backflow to the water source due to reverse siphon action.
The "VD-7N type" has a function that automatically introduces air into the negative pressure section to prevent the reverse siphon effect in the water supply system. It is a vacuum breaker used in piping sections where water pressure is always applied but reverse pressure does not occur. It incorporates a check valve and introduces air from the intake valve to reliably prevent backflow. Additionally, it comes standard with a test cock, allowing for functional checks of the check valve and intake valve while connected to the piping. 【Features】 ■ Air intake structure using a float design ■ Check mechanism employing a spring system that closes the valve before backflow occurs ■ Usable indoors ■ Function checks can be performed *For more details, please download the PDF or feel free to contact us.
