SJ200X可调试减压阀

结构及用途 Structure and purpose

该阀是一种利用介质自身能量来调节管路的压力，通过调节减压导阀，控制主阀的出口压力，出口压力不因进口压力的变化而改变，亦不受出 口用水量的变化而改变出口压力。密封性能可靠，安装、维护、调试、检查方便，使用寿命长。

This valve utilizes the self energy of a medium to adjust the pipeline pressure and controls the outlet pressure of the main valve via the adjustment of the pressure reducing pilot valve. The outlet pressure does not change along with the variation of the inlet one and of the water quantity at the outlet. Reli-able sealing performance, easy installation, maintenance, debugging and check, long duration.
