1. Van Điều Khiển Mức – Two-Way Flow Altitude Control Valve 106 / 206-A-Type 1  

  KEY FEATURES• No overflows
• Superior repeatability
• Positive shut-off
• Easily serviceable at ground level   TYPICAL APPLICATIONS  

  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.

2. Van Điều Khiển Mức – One-Way Flow Altitude Control Valve 106 / 206-A-Type 2  

    KEY FEATURES

+ No overflows – high level shut-off maintained to close tolerances

+ Superior repeatability

+ Positive shut-off

+ Easily serviceable at ground level TYPICAL APPLICATIONS  

  The 106-A-Type 2 and 206-A-Type 2 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 2 valve allows normal forward flow to fill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to refill the tank once the level drops a fixed distance below the high water level.Note: This valve does not operate as a check valve to prevent reverse flow.

3. Van Điều Khiển Mức – Two-Way Flow Altitude Control Valve with Differential Control 106 / 206-A-Type 3     

KEY FEATURES • No overflows • Superior repeatability while operating within close limits • Positive shut-off TYPICAL APPLICATIONS  

  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.

4. Van Điều Khiển Mức – Modulating Float Valve 106 / 206-F-Type 4

  KEY FEATURES • Maintains relatively constant level • Automatic compensation for level draw-down • Standard integral damping reduces hunting • Drip-tight at high level shut-off • Low supply pressure options TYPICAL APPLICATIONS  

  The Singer model 106-F-Type 4 and 206-F-Type 4 modulating float valves are based on the 106-PG or 206-PG main valve.They are ideal for balancing the inflow and outflow demand into the reservoir and maintaining level at the designated maximum.The valve closes drip-tight at the maximum level and modulates to maintain the tank level. The float pilot is remotely installed at the high level in the reservoir tank. Pilot connections to the main valve are connected in the field. As the reservoir level drops the main valve is opened proportionally to increase the filling rate. Movement of the main stem alters the size of the closing restriction, interrupting the tendency of the valve to hunt.

5. Van Điều Khiển Mức – One-Way Flow Altitude Control Valve with Differential Control 106 / 206-A-Type 4 

KEY FEATURES • No overflows • Adjustable draw-down level (differential) set-point • Superior repeatability • Positive shut-off • Adjustable draw-down for improved water cycling TYPICAL APPLICATIONS  

  The 106-A-Type 4 and 206-A-Type 4 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 4 allows normal forward flow to fill the reservoir to the maximum level, then closes drip-tight at the set-point. It opens to refill the tank once the level drops an adjustable amount below the high water level.Distribution from the reservoir is through a separate pipeline.Note: This valve does not operate as a check valve to prevent reverse flow.

6. Van Điều Khiển Mức – Non-Modulating Float Valve 106 / 206-F-Type 5

    KEY FEATURES • No overflow, drip-tight close
• Adjustable draw down
• Easily adjustable level settings • Low supply pressure options TYPICAL APPLICATIONS  

  The 106-F-Type 5 and 206-F-Type 5 non-modulating float valves are based on the 106-PG or 206-PG main valve. It is ideal for allowing normal forward flow to fill water reservoirs to a desired high level and where the pilot and valve of the reservoirs are easily accessible.The valve functions as a two position valve, either open or closed. The valve remains closed when the reservoir level drops, until the float reaches the pre-determined adjustable minimum reservoir level. The F-Type 5 valve then opens to refill the reservoir and closes tightly when high water level is achieved.
