廣州奧麗斯特燃?xì)庠O(shè)備有限公司一家專業(yè)從事進口燃?xì)庠O(shè)備的企業(yè),2009年在湖南正式簽約成為美國FISHER費希爾代理。所有產(chǎn)品FISHER費希爾工廠直供,原裝,支持官方驗證。(零二零-捌貳壹柒捌柒伍叁134*2361*0804劉小姐)Fisher289系列泄壓閥是一款彈簧負(fù)載式節(jié)流泄壓閥,可用作下游壓力調(diào)壓器,防止系統(tǒng)出現(xiàn)過壓。平穩(wěn)的節(jié)流操作在泄壓操作期間可限度地降低系統(tǒng)中的壓力沖擊。289系列泄壓閥是低壓設(shè)置的理想選擇,因為大閥膜面積可獲得更高的靈敏度。289系列泄壓閥設(shè)計用于壓力控制;它們不適合用作ASME泄壓閥。廣州簽約代理商奧麗斯特燃?xì)庠O(shè)備聯(lián)系電話:劉小姐134二三六一0804
