Equilibar’s BD Series back pressure valves with pipe sizes from 1.5″ up through 4″ handle higher flow applications. They use the same precision technology as our small back pressure regulators, but we use terminology “valve” in this case to denote the larger sizes. equilibar 的 bd 系列背压阀, 管道尺寸从 1.5 “向上到 4” 处理更高的流量应用。他们使用与我们的小背压调节器相同的精密技术, 但在这种情况下, 我们使用术语 “阀门” 来表示更大的尺寸。
The BD Series has external elbows attached to the bottom to save significant space compared with side-ported cylindrical designs. Stainless steel and aluminum valve bodies are welded to commercial pipe elbows, while PVC valves are glued to commercial elbows. Flanges can be optionally welded to the elbows if desired. Aluminum elbows are square in shape while stainless steel and PVC are rounded. bd 系列的外部弯头连接到底部, 与侧移圆柱形设计相比, 节省了显著的空间。不锈钢和铝阀体焊接在商业管弯头上, 而 pvc 阀门粘附在商业弯头上。如果需要, 可以选择将法兰焊接到肘部。铝肘的形状是方形的, 而不锈钢和 pvc 是圆形的。
BD valves are used for gases, liquids, and mixed phase applications. For liquid applications, an application engineer will discuss the downstream piping design to make sure that water hammer (resonance) does not cause an issue. bd 阀门用于气体、液体和混合相应用。对于液体应用, 应用工程师将讨论下游管道设计, 以确保水锤 (共振) 不会引起问题。
