Cast iron swing wafer check valve 19ch21br Pn 16

Cast iron check valves 19ch21br PN 16 are wafer-type rotary check valves that are designed to prevent backflow of the working medium in pipelines and operate automatically when the required flow pressure level is present.

Design and materials

The 19ch21br valves are made of cast iron with a brass seal. The main elements include a cast iron body and flap. The axis is made of steel.

Installation and operation

The valves can be installed on both vertical and horizontal pipelines. In a vertical system, the working medium flow must be from the bottom up with the sealing surface of the valve installed on top. In horizontal systems, the axis of rotation of the shut-off mechanism must be parallel to the base and above the pipeline axis. Before installation, the valve must be cleaned of conservation and contamination.
