美国舒稳ZW209H减压／恒压阀
Zurn ZW209H Pressure Reducing / Sustaining Valve

有些减压应用也要求上游压力能够维持稳定。型号ZW209H减压／恒压阀可以在同一阀体结构上实现两种（减压和恒压）功能。基本特点是能够减少维护和维修工作量，为用户提供最低的使用寿命全程成本。

Some pressure reduction applications also require upstream pressure maintenance. The ZW209H Pressure Reducing / Sustaining Valve provides both in a single configuration. Standard features ease maintenance and repair to provide the lowest ownership costs.
