Flanged silent check valve for water, and water with glycol from -10°C to 110°C

Series 903 metal seated silent check valves are designed to prevent back flow in high temperature range pumping applications. The valve element movement is controlled via a central guide where a centrally mounted spring together with the short movement aids the quick closing that is essential in reducing shock associated with valve closure. The pumped media can be water, glycol or other clean, neutral liquids.
Variant 903/20-001
Connection: Flanged
Material: Ductile iron
DN: DN65 - DN400
PN: PN 10/16

Features

  • The combination of light disc, short stroke distance and fast closing spring design effectively mitigates slamming
