Altitude Valve/ Level Control Valve Sewage

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


  • 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.
