Both are available in manual operation (hand wheel, gear box or lever) as well as with actuators (pneumatic or electric).

Questions to ask before choosing are;

  • Is the media abrasive?
  • Will there be large suspended solids?
  • Is there likely to be solid material present in the line when closing?

If the answer to any of the above question is yes then a knife gate valve is what you should be using.
