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
106 / 206-A-Type 3 Two-Way Flow Altitude Control Valve with Differential Control
The valve shall be a Singer Valve model 106-A-Type 3 / 206-A-Type 3, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16/ 25 or 40) pressure rating / flange standard, globe (angle), style valve. The Model 301-4 Altitude Pilot spring range (elevation) shall be “___ to ___” feet / meters, with set-point preset at Singer Valve to “___” feet / meters. The Model 625-RPD differential (delayed opening) range shall be “___” to “___” feet / meters, with set-point preset at Singer Valve to “___” feet / meters. Assembly shall be according to Schematic A-0414D.
The valve allows normal forward flow to fill the reservoir to the maximum level then closes drip-tight at the set-point It opens to allow reverse flow through the valve to distribute to users when the supply pressure drops an adjustable amount below the reservoir head. When a higher supply pressure is restored the A-Type 3 will then allow normal forward flow to refill the tank to the maximum level.
