Application scenarios
Oil and Gas Processing Pipeline Isolation
Used for shutoff and isolation in oil and gas processing lines. The one-piece valve body reduces potential leak paths, while the forward-preloaded resilient seat design supports bidirectional bubble-tight sealing under low-pressure or vacuum conditions; product literature lists it as suitable for oil and gas applications.
Safety Shutoff for Fuel Transfer Pipelines
Used for shutoff and isolation in fuel transfer pipelines. This series is certified to API 607 and ATEX, has an operating temperature range of -46°C to 343°C, and offers optional seat materials including PEEK and metal.
V-Ball Modulating Control in Automated Processes
Used for flow or pressure control in industrial processes. The RF15/RF30 series is available with V-ball control valve trim and, in certain sizes, an integrally cast ISO 5211 mounting pad to support actuator automation.
Municipal and Industrial Water System Isolation
Used for flow isolation in municipal or industrial water pipelines. This series is certified to NSF 61/372 and provides bidirectional bubble-tight sealing performance.
Selection points
One-Piece Investment-Cast Valve Body Design
The one-piece investment-cast floating ball valve body reduces potential leak paths created by body connections and supports bubble-tight sealing performance.
Smart Stem Live-Loaded Packing Compensation
Smaller sizes use Smart Stem live-loaded packing with Belleville washers for continuous preload, compensating for environmental changes and packing wear while reducing the need for routine packing adjustments.
Low-Torque Design with Ball Support for Larger Sizes
Larger sizes feature a bearing-supported ball design that reduces operating torque, making them suitable for larger line sizes requiring manual or automated actuation.
Multiple Seat Material Options
Valves are supplied standard with TFM 1600 seats and are available with Tek-Fil, PEEK, UHMWPE, RPTFE, and metal seat options, allowing seat materials to be selected based on operating conditions.
ISO 5211 Actuator Mounting Platform
Selected sizes feature an integrally cast ISO 5211 actuator mounting platform for convenient automated actuator installation. Available sizes should be confirmed in the product manual.
Installation & maintenance notes
Verify Pressure, Temperature, and Rating Limits
Before commissioning, verify that the actual pressure and temperature comply with the applicable pressure class and allowable temperature range for RF15 or RF30. Specific limits shall be based on the valve configuration and nameplate.
FAQ
What are the key design features of RF15/RF30 flanged ball valves?
RF15/RF30 features a one-piece precision-cast body design that reduces potential leakage paths, helping achieve bubble-tight sealing and lower operating torque. Larger sizes also incorporate a bearing-supported ball design to further improve operating performance.
What service conditions is this series suitable for?
RF15/RF30 is available in ASME Class 150 and 300 configurations, with sizes from NPS 1 to 12 / DN 25 to 300. It is suitable for applications requiring flanged connections, standard ports, and high sealing performance. Specific configurations must be confirmed based on the actual model and application conditions.
What is the value of the seat and sealing design?
This series uses a forward-preloaded elastomeric seat design that supports low-pressure/vacuum sealing and provides bidirectional bubble-tight sealing. This design is better suited to long-term operation in applications requiring stable shutoff performance and lower leakage risk.
What automation installation considerations apply to RF15/RF30?
This series provides an integrally cast ISO 5211 mounting platform to facilitate actuator installation and automated operation. Note that this configuration is not available in all sizes; actual availability must be confirmed for the specific model.
What points require attention during installation and maintenance?
1/2" to 2" models use Smart Stem™ technology with continuously energized internal packing; 2 1/2" to 12" models use a separate packing gland that can be adjusted without removing mounting hardware or actuators. The packing system compensates for environmental changes and wear through self-adjusting compression, helping extend service life.
