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.
Note: This valve does not operate as a check valve to prevent reverse flow
- No overflows - high level shut-off maintained to close tolerances
- Superior repeatability
- Positive shut-off
