一、产品[自力式差（微）压力调节阀]的详细资料：
产品型号：ZZC、ZZV型
产品名称：自力式差（微）压力调节阀
产品特点：挺扬牌ZZC和ZZV50mm.WC至0.1MPa自力式差（微）压调节阀是一种不需要外加能源的执行器产品。可用于公称压力PN0.1、PN10。差（微）压均可分段调节。从50mm.WC至0.1MPa。其用途十分广泛，可用于工业燃烧炉系统，控制两种物料，如煤气、空气流量配比，以达理想燃烧。用于氢冷发电机组密封油系统，控制密封油与氢气间压力差，以确保可靠密封。当差压阀的低压端通大气即为微压阀（差压阀负压，端压，力为零）。
二、特点：
● 无需停止生产即可进行设定值的调整；
● 无填料，阀杆上、下活动时不存在磨擦，上密封可靠
● 执行机构敏感元件极为灵敏，极微小的压力变化会被感测出来
● 阀体为四通形式，因而K、B型可通用一种阀体
