Overview
The Flow-Tek F15 Series flanged ball valve is an investment-cast, full-port ball valve engineered to ASME B16.34 Class 150 & Class 300 specifications. Available in sizes from ½” through 12″, this series combines durable stainless steel (CF8M) or carbon steel (WCB) construction with proven reliability in industrial fluid control applications. The F15 design prioritizes bubble-tight sealing and low operational torque, making it a dependable choice for systems requiring precision and long service life.
Key Features
- Floating ball design with low operating torque and extended cycle life
- Live-loaded, self-adjusting seals using Belleville washers for automatic compensation to temperature and wear
- Bubble-tight shutoff ensures zero leakage under static pressure
- Fire-safe certified to API 607 4th edition (graphite stem seals on fire-safe models)
- Trunnion-type ball support on larger sizes (2½”–12″) reduces operating torque
- ISO 5211 actuator pad integral to body for easy automation (½”–2″ sizes)
- Safety trigger handle prevents accidental valve movement; lockable with anti-tamper padlock option
- Double lock nuts allow safe handle removal under full line pressure
