Check valve DN 50 PN 10 Z GG25 2017166

Backflow prevention – reliable installation protection

This is a cast iron backflow preventer designed for use in installations with a diameter of DN 50 and a nominal pressure of PN 10. Its construction, made of gray cast iron (GG25), ensures durability and corrosion resistance. The device effectively prevents the backflow of medium, protecting installation components from damage caused by hydraulic shocks and ensuring stable system operation.

Construction and application

The preventer is designed to automatically close the pressure line, which is particularly important in systems where sudden changes in flow can lead to problems. It uses a spring-loaded cover as a closing element. It is an essential accessory in many applications, from home installations to industrial pumping systems. Because it is a replacement or complementary element, it allows for easy adaptation of existing installations to changing working conditions.
