Overview

Adjustable stem packing and stable support for high-cycle applications

Fire-Safe Design per API 607 for Safety in High-Temperature Environments

The F15/F30 Series flanged floating ball valves are investment cast, ASME B16.34 Class 150 and Class 300 full-port ball valves. This series offers a variety of optional trims and configurations, including V-ball control valve trims, and is widely used across global industries. The F15/F30 Series ball valves deliver exceptional value and reliable operation in a rugged flanged ball valve design suitable for a wide range of service conditions. The F15/F30 Series flanged ball valve design ensures bubble-tight shutoff and low operating torque. Sizes ½” - 2” feature Bray’s Smart Stem™ technology for internally continuously pre-loaded packing. Sizes 2½” - 12” feature an independent packing gland that can be easily adjusted without removing mounting hardware or the actuator. The packing gland features a special profile designed to distribute load evenly across the packing. The dynamic load packing is self-adjusting via Belleville springs, compensating for environmental changes and wear, ensuring maintenance-free operation and extended service life. Larger F15/F30 flanged ball valves feature bearing-supported ball construction to reduce operating torque. Soft-seated F15/F30 flanged ball valves feature positive pre-load design for low-pressure/vacuum sealing capability. All soft seat materials ensure bidirectional bubble-tight shutoff. F15/F30 Series flanged ball valves are available in stainless steel (CF8M), carbon steel (WCB), and special alloys (such as Alloy 20, Hastelloy, etc.), with other dissimilar alloys available on request. Non-fire-safe versions feature standard stem packing. API 607 fire-safe trims feature graphite stem packing. F15/F30 Series valves feature an integrally cast ISO 5211 mounting pad for easy automation. * * Not available on all sizes. Refer to product manual for details.

FAQ

How does the F15/F30 Series flanged ball valve maintain stem seal stability under high-cycle conditions?

This series features an adjustable stem packing design. Sizes NPS ½ to 2 feature Smart Stem™ technology with internally continuously pre-loaded packing; sizes NPS 2½ to 12 use an independent packing gland that can be adjusted without removing mounting hardware or the actuator. The packing gland cover distributes load evenly, and dynamic load packing with Belleville washers compensates for environmental changes and wear.

How should I choose between the F15 and F30 Series in terms of pressure class and connection standards?

The F15 Series is suitable for ASME Class 150, while the F30 Series is suitable for ASME Class 300. Valves are available with ASME Class 150, Class 300 flanged connections, as well as EN 1092 PN10, PN16, PN25, and PN40 connections. Selection should confirm piping flange standards, design pressure, and actual application conditions.

Is this series suitable for low-pressure or vacuum sealing applications?

Yes. The F15/F30 Series features a positive pre-load resilient seat design for low-pressure and vacuum sealing; the resilient seat materials provide bidirectional bubble-tight shutoff. Seat options include TFM 1600, Tek-Fil®, PEEK, RPTFE, UHMWPE, or metal, with specific configuration depending on media, temperature, and application conditions.

What configuration should be selected for high-temperature or fire-risk applications?

For fire-safe requirements, a version meeting API 607 is available. This version features API 607 fire-safe trim and graphite stem packing for enhanced safety in high-temperature environments. The valve temperature range is -46°C to 343°C. Actual selection should also consider pressure class, media, and seat material.

Is the F15/F30 Series easy to configure with pneumatic or electric actuators, and what maintenance considerations apply?

This series features an integrally cast ISO 5211 mounting pad for easy automation. Larger sizes feature bearing-supported ball construction to reduce operating torque. Maintenance should focus on stem packing condition and actuator connection; for NPS 2½ to 12 models, packing can be adjusted via the independent packing gland without removing mounting hardware or the actuator.
