The use of timber not only reduces the carbon footprint associated with the production and transportation of materials but also plays a role in promoting biodiversity when integrated into green spaces. These bollards can be designed to accommodate climbing plants or serve as bird perches, further enhancing urban ecosystems.
Gate valves operate with a simple mechanism they consist of a gate or wedge that moves up and down to open or close the flow path. When the gate is lifted, fluid flows freely; when it is lowered, the flow is completely obstructed. This design allows gate valves to provide minimal pressure drop when fully open, making them suitable for applications where uninterrupted fluid flow is essential.
