Väravakraanad
Väravakraanad are a type of gate valve used in plumbing and industrial applications. They are characterized by a flat, sliding gate that is raised or lowered to control the flow of fluid. When the gate is fully raised, the valve is open, allowing unrestricted flow. When the gate is fully lowered, the valve is closed, preventing any flow.
The mechanism for operating a väravakraana typically involves a handwheel that is turned to move a stem
Väravakraanad are commonly made from cast iron, brass, or stainless steel, depending on the application and
