費希爾Fisher 289P型指揮器作用式泄壓閥適用于為天然氣、空氣、丙烷或任何其他對內(nèi)部零件無腐蝕的工作介質(zhì)使用的下游系統(tǒng)提供過壓保護(hù)。 平穩(wěn)的打開操作在緊急操作期間可限度地降低系統(tǒng)中的壓力沖擊。 只需要設(shè)定壓力以上非常小的壓升，就能完全打開主閥，達(dá)到放泄流量。 外部控制管線可以提供迅速準(zhǔn)確的取壓。廣州奧麗斯特燃?xì)庠O(shè)備有限公司是美國FISHER產(chǎn)品華南區(qū)域（廣東?。┌瘓F(tuán)授權(quán)代理商。2020美國FISHER技術(shù)選型020*叁貳貳0162張S中國費希爾調(diào)壓網(wǎng) 【張工15876552411手機(jī)同微XIN】

如需其他技術(shù)信息

Fisher Type 289P pilot-operated relief valve is used to provide over pressure protection for downstream systems suitable for service on natural gas, air, propane, or any other operating medium not corrosive to the internal parts. Smooth opening action minimizes system pressure surges during emergency action. Very little buildup over set pressure is required to completely open the main valve for max relief capacity. The external control line provides quick, accurate pressure registration.
