106 / 206-A-Type 3 Two-Way Flow Altitude Control Valve with Differential Control

The 106-A-Type 3 and 206-A-Type 3 altitude control valves are based on the 106-PG or 206-PG main valve, and are ideal for maintaining preset maximum level.

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
