Model 106-A-Type 4

The M106-A- Type 4 altitude control valves are based on the M106-PG main valve, and 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 Type 4 allows normal forward flow to fill the storage tank 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. Note: Distribution from the storage tank is through a separate pipeline. This valve does not operate as a check valve to prevent reverse flow.
