4″ Manual Gate Valve (Replaceable O-ring Seat) – TTMA Flange x TTMA Flange

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. If a metal-to-metal seat valve is required, please see Betts line of metal-to-metal seat gate valves.
