BY-1压力调节阀也叫调压阀，通过压力调节装置实现从一次侧到二次侧的压强调整，基本原理为通过弹簧及气体的压力平衡来调节气体的压强。

BY-1压力调节阀

BY-1压力调节阀是一种自动调节压力的设备，主要由调节阀、执行器和指挥器组成。它不需要外部能源，依靠被调介质自身的压力变化来进行调节，适用于非腐蚀性的液体、气体和蒸汽等介质的压力控制。广泛应用于石油、化工、冶金、轻工等行业以及城市供热和供暖系统。

该调节阀的主要技术参数包括公称通径范围为DN15-300，公称压力为1.6MPa和4.0MPa，工作温度根据型号不同有所限制，如液体介质不超过140℃，气体介质不超过80℃。阀体材质根据压力等级使用铸铁或铸钢、铸不锈钢，阀芯材质为不锈钢。

在生产过程中，为了满足各种控制系统的需求，BY-1压力调节阀可以配备各种附件，如阀门定位器、阀位开关等，以增强其调节性能和定位准确性。

The BY-1 pressure regulating valve is an automatic pressure regulating device mainly composed of a regulating valve, an actuator,  a commander. It does  require external energy  relies on the pressure changes of the adjusted medium itself for regulation. It is suitable for pressure control of non-corrosive liquids, gases,  steam media. It is widely used in industries such as petroleum, chemicals, metallurgy,  light industry, as well as urban heating  heating systems.

The main technical parameters of the regulating valve include a nominal diameter range of DN15-300, a nominal pressure of 1.6MPa  4.0MPa,  working temperature limits depending on the model, such as liquids  exceeding 140°C,  gas media  exceeding 80°C. The valve body material uses cast iron  cast steel  cast stainless steel depending on the pressure rating,  the valve core material is stainless steel.

During the production process, in order to meet the needs of various control systems, the BY-1 pressure regulating valve can be equipped with various accessories, such as valve positioners, valve position switches, etc., to enhance its regulating performance  positioning accuracy.
