Cast Steel Floating Ball Valve

1. Product Description

Cast steel floating ball valves refer to floating ball valves that have cast steel valve body. These valves are mainly designed for low pressure services with a flexible temperature range. Metals Valve provides a wide variety of this series of ball valves manufactured to API, ASME, DIN, JIS and NOSOK standards. They are usually furnished with flanged end connection. Due to the low pressure ratings and small sizes, the torque to open or close the valve is not big hence manual operation(either lever or gear) is applied. Generally speaking, the cast steel floating ball valve is mainly used for on-off applications as well as minor throttling purpose.
