106 / 206-A-Type 1 Two-Way Flow Altitude Control Valve

The 106-A-Type 1 and 206-A-Type 1 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 1 allows normal forward flow to fill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to allow reverse flow through the valve when the supply pressure drops a fixed amount below the reservoir head.

When a higher supply pressure is restored, the Type 1 valve will then allow normal forward flow to refill the tank to the maximum level.

• No overflows
• Superior repeatability
• Positive shut-off
• Easily serviceable at ground level
