Cast iron non-return valves for high temperatures up to 300°C.
The check valves Fig. 406 and Fig. 407 are designed for use in pipelines with non-aggressive liquids, gas and steam. They meet the requirements of PED 2014/68/EU and offer a reliable solution for industrial applications.
The difference lies in the bolt pattern: Fig. 406 is the PN 16 version, Fig. 407 has a PN 10 bolt pattern from DN 200 to DN 300. The valve carries the CE mark to the Pressure Equipment Directive only from DN 32.
