Sometimes it is hard to choose between using a knife gate valve or a butterfly valve for certain applications.

Both have their merits and both should be picked according to the media and how it will be used.

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

Ask these questions before making the choice:

l Is the media abrasive?

l Will there be large suspended solids?

l Is there likely to be solid material present in the line when closing?

If the answer to any of the above question is yes, a knife gate valve is what you’re supposed to have.

Typical applications for knife gate valves include;

- Sewerage & Effluent

- Vacuum Trucks

- Fluid Transfer Trucks

- Slurry

- Grain Silos
