Water stop valve - Arjonstop

Water damage is the largest type of damage with insurance companies. The automatic water stop valve Arjonstop ® warns and shuts off the water if a water leak occurs. The coverage area is expanded by using the wireless sensors, which are placed in all rooms without drains. This makes it easy to turn off the water in the event of a leak for the water stop valve, even when no one is home. Once a day, an automatic test of the valve is performed, using the built-in automation for function check, to ensure that it works properly.

At low temperatures, the frost guard will warn when the temperature is low and close before the risk of freezing. The current in the motor is only on during opening and closing of the water stop valve, which prevents heat transfer and condensation in the electronics.

Advantages of using water stop valve - Arjonstop®

Notifies you in the event of a leak

Water stop valve information

The Ajonstop water stop valve consists of an engine-controlled ball valve, control unit, wired and wireless sensors, as well as the option of optional equipment such as wireless wall switch.

The control unit has wired connection with the motor-controlled ball valve connected to the housing water inlet.

The ball valve for the water stop valve has a robust design, and is made of drinking water approved plastic. To avoid pressure surges in the pipes, open and close them quickly and carefully. Arjonstop works even in the event of a power failure due to its built-in battery pack for operating the system for up to 6 hours.

Arjonstop Connect can be used with Arjonsmart. With this add-on solution you will get notification via your smartphone, and you will also have the option to turn on and off the water from your smartphone.

Arjonstop Connect

The automatic water stop valve can also be purchased with app control, which is an additional product Armaturjonsson offers. In the video you can see how the system works.
