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