Gate valve is a lift type of valve. The valve closure is a barrier(gate) which when lifted allows the flow to pass through the aperture. Gate valves are used only for isolation operations. The distinct feature of gate valves is the low resistance to flow when fully open.
Understanding the Knife Gate valve
It is a type of gate valve in which the barrier/gate has sharp bevelled edges on the bottom which cut through the flow containing suspended solids . It’s primary use is in the pulp and paper industry. Specialization includes handling slurry, viscous, corrosive and abrasive media.They are generally unidirectional.

To elaborate :
Valve closure element: Knife shaped flat disk
Valve closure mechanism: Plate connected to actuating mechanism
Advantages:
1) Low weight compared to other types of gate valves
2) Can be used for flow involving suspended flows
Disadvantages:
1) Unsuitable for low pressure applications.
2) Less used in applications involving sanitary and hygienic conditions
About the simulation:
The simulation is about a DN 50 knife edge gate in fully open condition. Tested for ON-OFF type operation this simulation predicts the pressure distribution around the valve seats. The max gross CV is 283.13 for full opening. Below are the images of flowlines, velocity and pressure contours taken from the app.
