Detailed Information

South American Valve are leading Uni Directional Knife Gate Valve Suppliers in Brazil.  A unidirectional knife gate valve is designed for handling thick, viscous fluids or those with high solid content, like slurry, wastewater, or pulp.

It only permits flow in one direction and offers a tight seal to prevent backflow. It typically consists of a sharp-edged blade or gate that moves perpendicular to the flow direction to control fluid flow. The gate is typically made of durable materials like stainless steel to withstand harsh conditions.


The valve body is usually made of cast metal or fabricated steel with an opening where the gate moves. In the closed position, the gate forms a tight seal against the valve seat, preventing flow. An actuator, such as a handwheel, pneumatic cylinder, or electric motor, is used to operate the valve. Engaging the actuator raises the gate to allow fluid to pass and lowers it to create a seal.
