3″ Manual Gate Valve (Replaceable O-ring Seat) – TTMA Flange x 3″ Threaded Pipe
The Betts replaceable o-ring gate valve is an economical manually operated external stop valve that offers a double action hand wheel for efficient closure. The replaceable o-rings provide a leak tight seal and protect the disc from scratches due to metal-to-metal contact. The PTFE encapsulated o-rings and 316 stainless discs offer premium corrosion resistance and the adjustable packing nut with woven PTFE infused packing allows for easy stem adjustments.
