Application scenarios
Tank Farm Storage and Transfer Pipeline Isolation and Switching
Used for flanged pipeline isolation or process switching on tank inlet/outlet lines, transfer headers, and branch lines in tank farms. The F15/F30 series features a full-port design and bidirectional bubble-tight sealing capability. Product documentation explicitly lists tank farm applications.
Municipal Water Treatment Network Isolation
Used for on-off isolation of process water lines, pump stations, and distribution branches in municipal water treatment facilities. This series covers NPS 1/2 through 12 in. sizes, features a full-port design, and is available in NSF 61/372-certified configurations. Product documentation explicitly lists municipal water supply applications.
Automated Flow Control and On-Off Control in Process Industries
When configured with a V-port ball and actuator, it can be used for automated on-off control or flow modulation in process media pipelines within process industries. Product documentation lists V-port ball configurations and an integrally cast ISO 5211 mounting platform to support automated operation.
High-Cycle Automated Shutoff in Process Industries
Used for automated opening, closing, and shutoff in process media pipelines within process industries. Product documentation states that this series is suitable for high-cycle applications and provides an ISO 5211 mounting platform to support automated operation.
Selection points
Full-Port Two-Piece Flanged Design
F15/F30 features a two-piece, full-port flanged ball valve design, available with ASME Class 150 or 300 and EN 1092 PN10, PN16, PN25, and PN40 end connections.
Live-Loaded Packing and Size-Specific Adjustment Design
This series uses live-loaded packing with Belleville washers to compensate for packing wear and environmental changes. Sizes from 1/2 to 2 inches use Smart Stem to maintain packing preload, while sizes from 2-1/2 to 12 inches use independently adjustable packing glands.
Multiple Seat Material Options
TFM 1600 is standard for valve seats, with Tek-Fil, PEEK, RPTFE, UHMWPE, and metal options also available. Seat configurations can be selected according to the process medium and operating conditions.
API 607 Fire-Safe Configuration
F15/F30 is available in fire-safe versions compliant with API 607. Fire-safe configurations use graphite stem packing.
Integrally Cast ISO 5211 Mounting Platform
The valve is supplied with an integrally cast ISO 5211 mounting platform for actuator installation and automation configurations.
Bearing-Supported Ball Design for Reduced Torque in Larger Sizes
Larger F15/F30 sizes feature a bearing-supported ball design to reduce operating torque.
Installation & maintenance notes
Verification of Pressure, Temperature, and Configuration Suitability
Before installation and commissioning, verify that site pressure, temperature, and the actual valve configuration comply with the allowable operating ranges for the F15/F30 series and the selected seat material.
Flange Connection Rating Compatibility
During installation, verify that the valve end flange standard and pressure rating match the mating pipeline flanges. F15/F30 is available with ASME Class 150, 300, and EN 1092 PN10, PN16, PN25, and PN40 connections.
FAQ
What is the operating principle and key advantages of F15/F30 flanged ball valves?
The F15/F30 Series features a flanged floating ball valve design that opens or shuts off flow through ball rotation. The series offers multiple trim configurations, low operating torque, and bubble-tight sealing to ensure reliability and sealing performance in high-cycle applications.
How is safety ensured for this series in high-temperature environments?
The series features a fire-safe design compliant with API 607 to ensure safety in high-temperature environments.
Which parameters should be prioritized during selection to ensure system compatibility?
Key considerations include size range (NPS ½–12 / DN 15–300), body material, temperature range, maximum allowable operating pressure, sealing and seat materials, and end connection standards (ASME/EN). The specific configuration must be confirmed based on the actual model and application conditions.
What are the features of the F15/F30 Series sealing and packing design?
Small-size models (½–2 inches) use Smart Stem technology for continuous internal packing preload. Large-size models use an independent packing gland that can be adjusted without removing the mounting hardware. The lined seats feature a positive preload design, providing bidirectional bubble-tight sealing.
What materials and certifications are available for this series, and are special materials supported?
Body materials include CF8M stainless steel, WCB carbon steel, and special alloys, with other dissimilar alloys available as required. Certifications include API 607, ATEX, CRN, NACE MR0175, NSF 61/372, PED, SIL, and others. Specific materials and certifications must be confirmed for the actual model.
