Finned Bonnet Fractional Flow Control Valve

The cooling fin bonnet option is for the protection of the stem packing from elevated temperatures associated with steam, hot water, and high temperature oil, gas and liquid services (up to 1000°F; 538°C). The finned bonnet cools the area around the packing, which permits the use of standard packing materials that otherwise would not be suitable for the service temperature conditions.
