The mechanism of a wedge type gate valve is relatively straightforward. When the valve is in the closed position, the wedge-shaped disc makes contact with the seats, creating a reliable seal that prevents fluid from flowing through. The angle of the wedge optimizes contact pressure, ensuring minimal leakage. As the handwheel is turned or the actuator is engaged, the stem moves up or down, causing the wedge to either lift or settle, thus controlling the valve’s open or closed status.


Bollards are not mere safety devices; they can also play a significant role in enhancing the aesthetic appeal of urban spaces. Available in various designs, materials, and colors, modern pedestrian bollards can complement the surrounding architecture and landscaping. For instance, cities can opt for decorative bollards that reflect historical themes, local culture, or artistic motifs, thereby contributing to a unique urban identity.


These bollards are typically made from durable materials such as polyethylene or rubber and can be found in various designs, colors, and heights. Their flexibility allows them to return to their original position after an impact, making them a sustainable choice for busy urban areas. In addition to their functional attributes, they can also be aesthetically pleasing, contributing positively to the urban landscape.
