Application scenarios
Isolation of high-temperature process pipelines
For flanged pipelines or equipment isolation points where high-temperature process media must be shut off. The metal seat features a Stellite® 6 overlay, with a maximum operating temperature of 399°C and shutoff performance from ANSI/FCI 70-2 Class V to Class VI.
Selection points
Wear- and High-Temperature-Resistant Stellite Metal Seat Configuration
The F15/F30 metal-seated versions use Stellite 6 seat overlay and can be configured with chromium carbide or hard chrome-plated ball surfaces for applications requiring wear resistance and high-temperature capability in metal sealing pairs.
Two-Piece Full-Port Flanged Body
F15/F30 features a two-piece full-port flanged body design for piping configurations requiring an unrestricted flow passage.
Size-Dependent Dynamic Packing Compensation Design
Smaller sizes use Smart Stem continuously preloaded packing, while larger sizes use an adjustable independent packing gland; Belleville washers provide dynamic load compensation for packing wear and environmental changes.
Integrally Cast ISO 5211 Mounting Platform
F15/F30 provides an integrally cast ISO 5211 mounting platform for convenient actuator installation and automated operation.
Installation & maintenance notes
Flange Connection and Pipeline Alignment
When installing F15/F30 flanged ball valves, ensure that the valve flanges are properly aligned with the mating pipeline flanges. Do not force misalignment correction by tightening the connections, as this may subject the valve body or flange joints to abnormal installation stresses and affect sealing performance.
Actuator Interface Matching and Abnormal Load Control
When configuring an actuator using the valve ISO 5211 mounting platform, verify that the actuator interface matches the valve mounting platform and avoid applying abnormal loads to the stem to ensure reliable automated opening and closing.
FAQ
What is the operating principle of F15/F30 Series flanged ball valves?
The F15/F30 Series uses a full-port floating-ball valve design with bubble-tight sealing. Media flow is opened or shut off by rotating the ball. Metal seats and various trim options provide high-temperature resistance, corrosion resistance, and low-torque performance for reliable sealing and stable flow control.
How should F15/F30 valves and trim configurations be selected?
Selection should consider the media, temperature, pressure rating (ASME 150/300, full port, NPS/DN ½–6 / DN 15–150), material requirements, and whether lined seats, metal seats, or V-ball control valve trim are required. The specific configuration must be confirmed based on the actual model and application conditions.
What design advantages does the F15/F30 Series offer for sealing and packing maintenance?
Sizes ½”–2” use Smart Stem technology for continuous internal packing preload, while 2½”–12” sizes use an independent packing gland that can be adjusted without removing mounted equipment. The stuffing box cover distributes load evenly, and dynamic packing self-adjusts through Belleville washers to accommodate environmental conditions and wear, supporting long-term maintenance-free operation.
What are the performance characteristics of this valve series in high-temperature environments?
Seats are available with Stellite® cobalt-chromium alloy overlay, providing excellent corrosion resistance, wear resistance, and high-temperature performance. The maximum operating temperature can reach high-temperature ranges, while metal seats provide reliable shutoff and sealing at elevated temperatures.
What are the key points for installation and field maintenance of the F15/F30 Series?
The valves feature an integrally cast ISO 5211 mounting platform for convenient automation connection. Field maintenance should follow the material and trim configuration selected for the application and include checks against the published testing and certification scope. Specific maintenance procedures must follow the actual model manual and application conditions.
