It is used in piping sections where water pressure is always present but reverse pressure does not occur. It incorporates a check valve and ensures reliable prevention of backflow by introducing air through the intake valve. Additionally, it comes standard with a test cock, allowing for functionality checks of the check valve and intake valve while connected to the piping. 【Features】 ■ Intake structure utilizing a float design ■ Check mechanism employing a spring system that closes the valve before backflow occurs ■ Usable indoors ■ Functionality checks can be performed *For more details, please download the PDF or feel free to contact us.
