Flanged Ball Valves

The 4000 Series (150 or 300 ANSI) of flanged ball valves targets such applications as refinery, petrochemical, and chemical-process equipment.

Valves come with carbon steel or stainless-steel bodies and stainless-steel balls and stems, and are fire-tested to API607 4th Edition and ISO 10497. When fitted with a spring-return actuator, they provide a fail-safe, automatic shutoff, avoiding manual intervention in dangerous settings.
