| 127-1 (截止阀) / 1127-1 (角阀)
水位控制阀 - 单路流量（容器注入）
（DN150及以上采用118-4R/6118-4R）
127-1 (Globe) / 1127-1 (Angle)
ALTITUDE VALVE - ONE WAY FLOW (TANK FILL)
具有自动注水提升容器或蓄水池水位的功能。当水位控制器感应到水位下降到预置设置点以下时，则阀门开启，开始对容器注水。供水压力大于落差压力。容器的排放是通过独立的管线实现的。
Provides automatic filling of elevated tanks or
reservoirs. When the altitude control senses a drop in level below the
predetermined setpoint the valve opens to fill tank. Supply pressure is
greater than static head pressure. Discharge of the tank is by a separate
line.
注：
调节范围：5-20英尺
10-75英尺
50-200英尺
NOTE:
Adjustment range: 5-20 FT.
10-75 FT.
50-200 FT.
附加的组合功能：
127-11（截止阀） / 1127-11（角阀）水位控制阀 - 单路流量（容器注入） - 延时开启，用于调节容器水位下降。延时水位下降调节范围：2~15英尺。
Additional combination functions:
127-11(Globe) / 1127-11(Angle) Altitude Valve - One Way Flow (Tank Fill)
- Delayed Opening for Adjustable Tank Draw-Down Adjustment range delayed
level drop: 2-15 FT.
快速选型：阀门通径，管线口径，或者小一个等级。
QUICK SIZING: Valve
size, line size or one size smaller.
需要考虑的因素
Points to consider:
- 参阅技术参数 - 流量表中所需流量的压降
Refer to Engineering Data - Flow Capacity Chart
Pressure drop at required flow
- 参阅技术参数 - 压降表
Refer to Engineering Data - Pressure Drop Chart
- 进口压力与容器高度进行对比，已确定是否需要注水
Inlet pressure vs. tank height to fill
- 如果要求阀门通径小于管线通径，请考虑ACV 6127-1
咨询美国瓦茨ACV销售代表/工厂
If valve size required is smaller than line size,
consider ACV 6127-1
