Check valve 6/4 inch with flap, PN16 ZZK5

Check valve is an essential element of every water and heating installation, protecting against unwanted backflow. The ZZK5 model from Ferro, made of high-quality brass, ensures reliable operation and long service life. Designed for use with water, it is perfect for both domestic installations and more demanding systems.

This valve is characterized by a 6/4 inch (1 1/2 inch) connection with a tapered internal thread (NPT), which facilitates installation and ensures a tight connection. Its flap-based design, combined with an NBR seal, guarantees effective blocking of backflow while minimizing resistance to flow in the correct direction. The maximum operating temperature is 100°C, and the maximum working pressure is 16 bar – these parameters allow the valve to be used in a wide range of operating conditions.

It is worth noting the NICKEL FREE technology used in this model. This means that the valve surface in contact with water is not nickel-plated, which is particularly important for protecting health and the environment. Additionally, the valve plug is sealed with PTFE, which increases its durability and corrosion resistance. Thanks to precise workmanship and the use of high-quality materials, this valve is a solid investment in the safety and efficiency of the installation.
