Grey and Ductile cast iron Knife Gate Valve

Knife gate valves can be mounted horizontally or vertically. They can be unidirectional or bidirectional. The unidirectional knife gate valves have pads that support the blade and allow it to work with a back pressure of 30% of the maximum working pressure. The unidirectional knife gate valves have pads that support the blade and allow it to work with a back pressure of 30% of the maximum working pressure. The bidirectional knife gate valves can receive pressure from both directions. When assembling these valves, it is necessary to remember to hold them tightly in the gland between the flanges. The knife gate valve provides full flow to provide high flow rates and minimal pressure drop.

This implies that in the open position it does not produce cavitations and there are no turbulences in the fluid. The knife gate valves are suitable for the passage of fluids or powders such as drinking water, waste water, other inert fluids. They can be used for water treatment, in the chemical and cellulose industries. The inside of our valve is designed to prevent the accumulation of solids and is conical in shape so when closed the solid residues inside are easily released. In standard version they are supplied with a handwheel but can be operated on request with pneumatic or electric actuator.
