Pressure Rating
Features & Benefits:
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.
