The Flow-Tek F15/F30 Flanged Series ball valve,
featuring 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.
½” – 2” valves feature Flow-Tek's Smart Stem. This stem is
self-adjusting due to its Belleville washers allowing it to compensate
for environmental changes and wear. 2 ½” – 12” valves utilize an
independent packing gland which can be easily adjusted without removing
mounting hardware or operator. The packing gland is contoured to
uniformly distribute the load across the packing.
Flow-Tek’s seat design ensures bi-directional, bubble-tight sealing with
low operating torque. All resilient seats feature relief slots or seat
outer diameter clearance to relieve pressure past the upstream seat, and
positive preloading to ensure low pressure/vacuum sealing.
