产品简介
进口Lowara美国罗瓦拉品牌【进口减压稳压阀】是为使用功能为满足管路内压力平衡在安全系数要求范围内的特殊控制阀。采用管路内进口、出口自身压力自动驱动导阀，实现阀门对管路内压力，减压稳压特点，从而满足管路系统实际需求。
综合减压阀和泄压阀的功能
维持用户端管道的压力；当管道压力超过设定值时，阀门自动打开，把多余的压力释放到下游；当管道压力低于设定值时，阀门关闭；
维持较低的出口压力，不管进口压力和流量如何变化；
The Model 520 Combination Pressure Reducing and Pressure Sustaining Valve
automatically performs two independent functions. It maintains a constant downstream pressure, regardless of fluctuating demand and sustains the upstream pressure to a pre-determined minimum.The pressure reducing control responds to slight variations in downstream pressure and immediately repositions the main valve to maintain the desired downstream pressure. The pressure sustaining control is normally held open by the upstream pressure,but modulates should the pressure drop to the control set point.This, in turn, modulates the main valve to sustain the desired upstream pressure.
200Y 可用于中等压力的供水系统，提供平稳和精确的压力控制。200YN 是带塑料导阀的，因此特别适用于灌溉和低压工况。它还可用于民用建筑，水处理及过滤系统。导阀的塑料材料和阀门的简单设计使200YN 具有优越的防腐性能并价格低廉。
