      The Series 416 features a bolted cover design for secure maintenance access and an integral seat to eliminate leak paths behind the seat ring. Internal hardware, including bolts and spring washers, is constructed from 304 stainless steel. The Series 416 utilizes an RTFE gasket as standard, with Grafoil and 316 SS sheet options available for high-temperature service. Manufactured to ASME B16.34 and tested per API 598, this series is also available in a Class 300 configuration for higher-pressure requirements.

      Available in sizes from 1/2" to 12".

      • The Chicago Valves Series 416 is a heavy-duty stainless steel solution designed for critical non-return flow regulation in high-purity and corrosive environments. By utilizing a high-integrity swing-type disc, this series provides a reliable barrier against reverse flow without the significant pressure drop associated with other check valve designs. The precision-cast construction is specifically optimized for 'severe service' pipelines where material longevity and simplified maintenance are essential to operational uptime

        The Series 416 is available from 1/2" to 12" and is also offered in Class 300 configurations.
