South American Valve is one of the top  Uni Directional Knife Gate Valve Suppliers in Brazil. A unidirectional knife gate valve is specifically designed to tackle thick, viscous fluids or fluid-based materials containing a significant amount of solids such as slurry, waste water, or pulp. It only allows flow in one direction and provides excellent sealing against backflow. It usually takes the form of a sharp-edged blade or gate and moves perpendicular to the fluid flow direction to control that fluid flow. The gate is typically made of some very strong materials. These materials are resistant to harsh conditions such as those found with the use of stainless steel.

The valve body of cast metal or fabricated steel is almost always drilled with an opening that the gate passes through. The gate makes a tight seal against the valve seat to prevent flow when it's in the closed position. Some form of actuator, including a handwheel, pneumatic cylinder, or electric motor, has to be engaged to open up the valve. This allows the actuator to raise the gate for flow to take place while lowering it to seal off.
