费希尔FISHER 75A 型调压器设计用于降低家用或工业用水压力，从而防止管道设施和仪表高压冲击下损坏。 75A 型阀门采用自给式设计，无需外部控制管路即可工作。 下游压力直接在阀膜上取压。 随着下游压力升高，阀膜的力克服弹簧压力，使阀盘升高，降低通过调压阀的流量。广州奥丽斯特燃气设备有限公司是美国FISHER产品华南区域（广东省）艾默生集团授权代理商。2020美国FISHER技术选型020*叁贰贰0162张S中国费希尔调压网【张工15876552411手机同微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.
