Check valve 2- 1/2 inch ZZ7W

Check valve is an essential component of an installation that prevents backflow of the medium – in this case, water. Model ZZ7W, with a diameter of 2 1/2 inches, is designed for reliable operation and durability. Made of high-quality brass, it guarantees corrosion resistance and long service life.

This valve is characterized by an internal tapered (NPT) threaded connection, which facilitates installation and ensures a tight connection. The sealing element made of ABS effectively blocks flow in one direction. This protects the installation from potential damage caused by backflow of water, e.g. in the event of a water supply network failure or during maintenance work.

• Durability and reliability: The brass body resistant to corrosion ensures long-term use.
• Effective protection: Prevents backflow of the medium, protecting the installation and equipment.
• Easy installation: Internal tapered (NPT) thread facilitates quick and tight connection with pipes.
• Wide application: Ideal for water installations in residential, commercial and industrial buildings.
• Safety: The valve is nickel-free (NICKEL FREE), which increases safety, especially in potable water installations.

The check valve ZZ7W is suitable for both new installations and for modernization of existing systems. Its solid construction and precise workmanship guarantee trouble-free operation for many years. The nominal working pressure is 10 bar, which makes it suitable for most standard water installations.
