Singer Valve - Model 106/206-A-Type 2 - One-Way Flow Altitude Control Valve

The 106-A-Type 2 and 206-A-Type 2 altitude control valves are based on the 106-PG or 206-PG main valve and are ideal for maintaining a preset maximum water level. The valve functions as a two position control valve, either fully open or fully closed. The Type 2 valve allows normal forward flow to fill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to refill the tank once the level drops a fixed distance below the high water level.

Key Features

  • No overflows - high level shut-off maintained to close tolerances
  • Superior repeatability
  • Positive shut-off
  • Easily serviceable at ground level
