What is flange gate valve ?

flange gate valve is widely used shut-off valve,in water industry,water supply and drainage,waste water treatment,urban water supply system.

  • it's normally designed with a wedge disc,like the soft seat gate valves.the difference is that the sealing of valve is metal to metal,brass,bronze,or stainless steel.
  • the benefits of metal to meal sealing is that the valve will be suitable for more severe working conditions,and much longer life.
  • The wedge has a machined groove in its central part providing flexibility at the disc.
  • Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.
  • Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.
