106 / 206-A-Type 3 Two-Way Flow Altitude Control Valve with Differential Control
The Type 3 allows normal forward flow to fill the reservoir to the maximum level, then closes drip-tight at the set-point. The valve opens to permit reverse flow through the valve when the supply pressure drops an adjustable amount below the reservoir head.
The Type 3 will then allow normal forward flow to refill the tank to the maximum level, when a higher supply pressure is restored.
- No overflows
- Superior repeatability while operating within close limits
- Positive shut-off
