Cast iron lifting flanged check valve 16ch6nzh Pn 16

Сast iron flanged lift check valves 16ch6nzh PN 16 are designed to protect the pipeline from backflow, which can create emergency conditions in some cases. The check valves are designed to work with such media as water, steam, oil products and other non-aggressive liquids at temperatures up to 225°C. Connected to the pipeline using flanges.

Operating principle

Lift check valves 16ch6nzh operate automatically under the pressure of the working medium. In a static state, the spool lowers onto the seat under its own weight, which closes the valve for backflow. When the working medium moves in one direction, the spool rises, allowing the working medium to pass through the valve.

Application

Valves 16ch6nzh are widely used in water supply and heating systems to protect pipelines from possible emergency situations associated with the reverse flow of the working medium.
