Kiilaventtiilejä

Kiilaventtiilejä, also known as wedge gate valves, are a type of industrial valve used to control or regulate the flow of a fluid. They are characterized by a flat or V-shaped gate that fits snugly between the valve seats. When the valve is fully open, the gate is lifted completely out of the flow path, allowing for full, unobstructed flow. When the valve is closed, the gate is lowered, sealing against the seats and preventing flow.

The operation of a kiilaventtiili is typically achieved through a handwheel or an actuator. Turning the handwheel raises or lowers the stem, which in turn moves the wedge gate. This design offers a good seal when fully closed, making it suitable for applications where a tight shut-off is required. They are commonly found in water distribution systems, oil and gas pipelines, and other industrial processes.

Kiilaventtiilejä are generally used for on-off service rather than throttling or regulating flow. This is because partially opening the wedge can lead to vibration and wear on the gate and seats, potentially reducing the valve's lifespan and effectiveness. They are known for their simple design and relatively low operating torque when fully open. However, their operation can be slower compared to other valve types like ball valves. The materials used for kiilaventtiilejä vary depending on the application and the type of fluid being handled, with common options including cast iron, steel, and stainless steel.
