Screw coupling with check valve – reliability and installation protection

This brass screw coupling, equipped with a built-in check valve, is a key element of water meter installations. It provides not only a solid connection but, above all, protects the system from backflow, which is particularly important in multi-family buildings and commercial facilities. The brass construction guarantees durability and corrosion resistance, and the plastic check valve effectively prevents water from flowing back.

Construction and application

The BKM coupling is designed for direct mounting behind the water meter. Its task is to protect the measuring device and the entire water installation from the effects of possible water backflow. This ensures accurate measurements and minimizes the risk of damage. Threads made in accordance with UNI-ISO 228/1 class B standard guarantee tightness and easy installation.

• Application: Water meter installations in residential, commercial and industrial buildings.
• Material: Brass – provides strength and corrosion resistance.
• Check valve: Made of plastic, effectively blocks reverse water flow.
• Working pressure: Safe operating range from 0.05 to 16 bar – suitable for most water installations.
• Thread: GZ 3/4" - standard size allowing easy connection to existing installation.

Why choose the BKM coupling?

• Water meter protection: Prevents damage caused by backflow, extending the life of the measuring device.
