Wafer Butterfly Valve With Single Gear Box FGBW-300
FM Approved resilient seated non-rising stem (NRS) gate valve with flanged end connections, conforming to AWWA C515 and BS5163 with fusion bonded epoxy coating compliant with AWWA C550. The 300 PSI rated standard size range counterpart to the large-bore FGN909-250, covering 50mm (2″) to 300mm (12″) and compatible with both ANSI and EN flange standards. The compact NRS design makes it suitable for installations where headroom is limited or a rising stem is not practical.
