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 系列背壓閥, 管道尺寸從 1.5 “向上到 4” 處理更高的流量應用。他們使用與我們的小背壓調節器相同的精密技術, 但在這種情況下, 我們使用術語 “閥門” 來表示更大的尺寸。
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 系列的外部彎頭連接到底部, 與側移圓柱形設計相比, 節省了顯著的空間。不銹鋼和鋁閥體焊接在商業管彎頭上, 而 pvc 閥門粘附在商業彎頭上。如果需要, 可以選擇將法蘭焊接到肘部。鋁肘的形狀是方形的, 而不銹鋼和 pvc 是圓形的。
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 閥門用于氣體、液體和混合相應用。對于液體應用, 應用工程師將討論下游管道設計, 以確保水錘 (共振) 不會引起問題。
