Altitude Control Valve or Level Control Valve is ideal for maintaining a preset maximum water level. The valve functions as a two position control valve, either fully open or fully closed. The types allow normal forward flow to fill the reservoir to the maximum level, then closes drip-tight at the set-point. It opens to refill the tank once the level drops an adjustable amount below the high water level. Distribution from the reservoir is through a separate pipeline.
Note : This valve does not operate as a check valve to prevent reverse flow
Features
- No overflows
- Adjustable draw-down level (differential) set-point
- Superior repeatability
- Positive shut-off
- Adjustable draw-down for improved water cycling
Typical Application
- Higher Pressure Supply
- Reservoir Tank
- Provide connection to drain for displaced water from bonnet
- Distribution to users
- Sensing connected to drain line or to the reservoir directly (completed by others). Slope to avoid air pockets.
