468S Stop-check valve flanged, straight form

Material: DN 10-50 P245GH; DN 65-350 GP240GH

Nominal pressure: PN 40

Nominal diameter: DN 10-300

Temperature range: 450°C

Working position: any

Screw down non-return valves as one-way type prevents the pipelines against reverse flow of medium. Additionally function allows to stop the medium flow. The valves should be installed on the pipeline in horizontal or vertical position with handwheel in upper position, paying attention on correct flow direction, that should be in accordance with marking on the body.
