費希爾FISHER 75A 型調(diào)壓器設(shè)計用于降低家用或工業(yè)用水壓力，從而防止管道設(shè)施和儀表高壓沖擊下?lián)p壞。 75A 型閥門采用自給式設(shè)計，無需外部控制管路即可工作。 下游壓力直接在閥膜上取壓。 隨著下游壓力升高，閥膜的力克服彈簧壓力，使閥盤升高，降低通過調(diào)壓閥的流量。廣州奧麗斯特燃氣設(shè)備有限公司是美國FISHER產(chǎn)品華南區(qū)域（廣東省）艾默生集團授權(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手機同微XIN】

Type 75A regulator is designed to reduce domestic or industrial water pressure, thus protecting plumbing fixtures and meters from high pressure surges. Type 75A is self-contained, requiring no external control line for operation. Downstream pressure is directly registered under the diaphragm. As the downstream pressure increases, the diaphragm force overcomes the spring compression, causes the valve disk to rise, and reduces flow through the regulator.
