Flow-Tek’s F15/F30 Flanged Series ball valves feature a floating ball design for low torque and increased cycle life. As standard, larger sized valves feature trunnion– type ball support. These rugged ball valves are ideal for industrial applications.
Secure Mount
Flanged Series valves offer ease of automation due to an integrally cast actuator mounting pad which complies with ISO 5211 through 2” valve sizes.
Ball Support
For larger valve sizes, Flow-Tek’s unique trunnion–type mounting supports the ball. This support maintains a constant seat profile, preventing seat damage and blow-by. The results are less seat wear, lower torque and a longer service life. The Flow-Tek ball support dramatically improves valve performance at a much lower cost than traditional trunnion mounting. This feature is standard on 10”-12” Model F15 and 6”-12” Model F30 valves.
Fire Safe: API 607-4 Certified
Flow-Tek’s Flanged Series valves with graphite stem packing meet the highest fire safety standards under extreme conditions. In the event of a fire, after heat destroys the primary resilient seat, the ball makes contact with the secondary metal seat, forming a secure seal. The body seal,
composed of stainless steel and graphite wound into a spiral, prevents external leakage. The graphite stem rings prevent stem leakage. All valves have anti-static devices as standard– ball and stem are positively grounded.
