PRESSURE REDUCING / CHECK
无论流速和进口压力如何变化,都能够把较高的进口压力减少到恒定较低的出口压力水平上。配置一个液力止回阀,防止压力逆向时出现倒流。
Automatically reduces a higher inlet pressure
to a constant lower outlet pressure regardless of changing flow rate and/or
varying inlet pressure. Equipped with a hydraulic check feature to prevent
reverse flow on pressure reversal.
注:
调节范围:
标准:20-175 psig
选项:0-30 psig
100-300 psig
(不锈钢控制器)
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig
(stainless steel control)
快速选型:阀门通径比管道口径小一级。
QUICK SIZING: Valve size one
size smaller than line.
需要考虑的因素
Points to consider:
- 参阅技术参数 - 减压选型
See Engineering Data - Pressure Reducing Sizing
- 确定最大和最小流量
Check maximum and minimum flow
- 确定压降 - 减压阀或气穴图表
Check pressure drop - pressure reducing valves
or cavitation chart
- 如果要求阀门通径小于管线通径,请考虑ACV 6115-3
咨询美国瓦茨ACV销售代表/工厂
If valve size required is smaller than line size,
consider ACV 6115-3

阀门性能
VALVE FUNCTION
- 将较高的进口压力降低到恒定较低的出口压力(可调节)上
Reduce higher inlet pressure to constant
lower outlet pressure (adjustable)
- 当出口/下游压力超过进口/上游压力时关闭
Close when outlet/downstream pressure exceeds
inlet/upstream pressure
