The SCN slam shut valves are available in 1”-10” sizes in ANSI 150# rating in Ductile Iron and LCC steel body configurations with available set points pressure ranges from 4”W.C -285 psig. SCN slam shut models feature a true “spring assist fail closed design”. Suitable applications would include shale gas MAOP protection, pipeline MAOP protection, power plant feeds, city gate stations, compressor fuel gas as well a district regulator settings.

The SCN slam shut valves offer superior durability for high and low pressure safety control applications where reliably and durability are paramount.

SBC 782 is a safety device, also called slam shut valve, suitable to quickly interrupt the gas flow when the pressure reaches a calibration set value. This device is mainly used in high-pressure transmission systems and in medium pressure gas distribution networks.

SBC 782 is suitable for natural gas and all non-corrosive gaseous media. Its “top entry” design allows for easy maintenance without removing the body from the pipeline.

The HBC slam shut valves are available in 4”-12” sizes in ANSI 300# -600# rating in ductile Iron and LCC steel body configurations with available set points pressure ranges from 4”W.C -1400 psig. These slam shut models feature a true “spring assist fail closed design”. Suitable applications would include shale gas MAOP protection, pipeline MAOP protection, power plant feeds, city gate stations, compressor fuel gas as well a district regulator settings.

The HBC and SCN slam shut valves offer superior durability for high and low pressure safety control applications where reliably and durability are paramount.
