Let Waits Valve introduce this product to you:

Gate valves, also known as knife valves, are used to control fluid flow as you can imagine. Gate valves are used for linear motion and are equipped with a flat closing element that slides into the fluid and closes the fluid. They are one of the most commonly used valves.

Double Disc Flat Gate Valve can cut off mud and other viscous substances such as heavy oil, grease, molasses, varnish, thick cream, etc. However, they can be used for throttling, but excessive throttling will cause wear on the disc and seat of the gate valve.
