115-4 (Globe) / 1115-4 (Angle)
PRESSURE REDUCING / SOLENOID ON-OFF
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。配置一个电磁阀过载装置,便于通过电源开-关来操作阀门。
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 solenoid override feature allowing
for electrical on-off operation of the valve.
注:
调节范围:
标准:20-175 psig
选项:0-30 psig
100-300 psig(采用不锈钢控制器)
电磁阀最大工作压力:订购时,请告知工厂实际系统工作压力,以便进行正确的电磁阀选型。(如果压力超过150 psig,请咨询工厂)。
外壳:NEMA 1, 2, 3, 3S, 4, 4X
选项:防爆NEMA 3, 3S, 4, 4X, 6, 6P, 7, 9
NOTE:
Adjustment range:
Standard: 20-175 psig
Optional: 0-30 psig
100-300 psig (uses stainless steel control)
Solenoid max W.P.: At time of order, advise factory actual system working
pressure for correct solenoid selection. (consult factory if over 150
psig).
Enclosure NEMA 1, 2, 3, 3S, 4, 4X
Optional: explosion proof NEMA 3, 3S, 4, 4X, 6, 6P, 7, 9
附加的组合功能:
115-5减压/电磁/止回
Additional combinations:
115-5 Pressure Reducing/Solenoid/Check
具体说明:
通电后开启还是通电后关闭主阀。
SPECIFY:
Energized to open or energized to close main valve.
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 6115-4
咨询美国瓦茨ACV销售代表/工厂
If valve size required is smaller than line size,
consider ACV 6115-4
Consult Watts ACV representative/factory
