KEY FEATURES• No overlows• Superior repeatability

• Positive shut-off

• Easily serviceable at ground level

Product OverviewThe 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 low to ill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to allow reverse low through the valve when the supply pressure drops a ixed amount below the reservoir head.

When a higher supply pressure is restored, the Type 1 valve will then allow normal forward low to reill the tank to the maximum level.

Speciications • The valve shall be a Singer Valve model 106-A-Type 1 / 206-A-Type 1, size “_____”, ANSI Class

150 (ANSI 300, ANSI langes drilled to ISO PN 10 / 16 / 25 or 40) pressure rating / lange 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. Assembly shall be according to Schematic A-0412D.

• The valve allows normal forward low to ill the reservoir to the maximum level then closes drip-tight at the set-point. It opens to allow reverse low through the valve to distribute to users when the supply pressure drops a ixed amount below the reservoir head. When a higher supply pressure is restored the Type 1 will then allow normal forward low to reill the tank to the maximum level.

• Refer to Main Valve section, page 11, 106-PG (or 206-PG) and Main Valve Options section, Model X107 Position Indicator for detailed information pertaining to valve sizes and materials, selection criteria and speciications.

• Refer to Pilot and Accessories, page 266, section, Model 301-4 Altitude Pilot for detailed information pertaining to materials and speciications.

Selection Summary1. Generally select line size to minimize losses during normal forward low.2. Use the performance curves and sizing bulletin to determine the pressure drop across the valve.

3. Limit maximum continuous low velocity to 20 ft/s / 6 m/s for 106 and 16 ft/s / 5 m/s for 206. Consult Singer Valve if higher lows are expected.

4. The pilot system exhausts to atmosphere, ensuring the valve opens fully; requires that the displaced volume of water be taken to drain with each opening.

5. Select pilot spring range: 4 to 20 ft / 1 to 6 m; 10 to 60 ft / 3 to 18 m; 40 to 125 ft / 12 to 38 m; 60 to 220 ft / 18 to 67 m.

6. There is a non-adjustable differential required between the reservoir head and the supply pressure in order for the valve to open. It ranges from 2 ft / 0.6 m to 5 ft / 1.5 m for the pilot spring ranges listed.

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

Product OverviewThe Singer model 106-F-Type 4 and 206-F-Type 4 modulating loat valves are based on the 106-PG or 206-PG main valve. They are ideal for balancing the inlow and outlow 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 loat pilot is remotely installed at the high level in the reservoir tank. Pilot connections to the main valve are connected in the ield. As the reservoir level drops the main valve is opened proportionally to increase the illing rate. Movement of the main stem alters the size of the closing restriction, interrupting the tendency of the valve to hunt.

Assembly shall be according to Schematic A-0608D.

• The valve allows low into the reservoir in order to maintain the level at the designated maximum. The valve closes drip-tight at the maximum level. As the reservoir drops, the main valve opens proportionally (modulates) to increase the illing rate in an effort to maintain the maximum reservoir level.

• Refer to Main Valve section, see page 11, 106-PG (or 206-PG) for detailed information pertaining to valve sizes and materials, selection criteria and speciications.

• Refer to Pilot and Accessories section, see page 267, Model R-400 Modulating Float Pilot for detailed information pertaining to materials and speciications.

Selection Summary1. Generally select line size to minimize losses during normal forward low.2. Use the performance curves and sizing bulletin to check the pressure drop across the valve at

KEY FEATURES• No overlow, drip-tight close• Adjustable draw down

• Easily adjustable level settings

• Low supply pressure options

Product OverviewThe 106-F-Type 5 and 206-F-Type 5 non-modulating loat valves are based on the 106-PG or 206-PG main valve. It is ideal for allowing normal forward low to ill 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 loat reaches the pre-determined adjustable minimum reservoir level. The F-Type 5 valve then opens to reill the reservoir and closes tightly when high water level is achieved.

Typical ApplicationNon-modulating loat valves are typically used in buildings with reservoir tanks or installations where the valve and pilot are readily accessible.

The on / off service ensures that the reservoir contents are cycled. It will also prevent over cycling of the supply pumps as the minimum quantity per cycle is adjustable.

Speciications• The valve shall be a Singer Valve model 106-F-Type 5/ 206-F-Type 5, size “_____”, ANSI

Class 150 (ANSI 300, ANSI langes drilled to ISO PN 10 / 16 / 25 or 40) pressure rating / lange standard, globe (angle), style valve. The Model 43 Non-Modulating Float Pilot shall be utilized with a 4 ft / 1.2 m brass loat rod with adjustable stops and a copper loat (connection between main valve and Model 43 Non-Modulating Float Valve by others). Assembly shall be according to Schematic A-0421C.

• The valve allows low into the reservoir to the maximum high level where it closes drip-tight. The valve remains close when the reservoir level drops until the loat reaches the pre-determined minimum reservoir level at which time it opens to reill the reservoir.

• Refer to Main Valve section, page 11, 106-PG (or 206-PG) for detailed information pertaining to valve sizes and materials, selection criteria and speciications.

• Refer to Pilot and Accessories section, page 271, Model 43 Non-Modulating Float Pilot With Vertical Rod for detailed information pertaining to materials and speciications.

Selection Summary1. Generally select line size to minimize losses during normal forward low - see chart of maximum

continuous low below.2. Use the performance curves and sizing bulletin to determine the pressure drop across the valve at

normal low rate.3. Check the maximum operating pressure against the maximum working pressure rating

of the langes.4. If the outlet pressure is less than 35% of the inlet pressure, check for cavitation.

5. If the inlet pressure is less than 10 psi / 0.70 bar higher than the reservoir head, consult with Singer Valve. Assisted opening may be required for full low.

– To maintain a relatively steady tank level, refer to model 106-F-Type 4 / 206-F-Type 4: Modulating Float Valve, 194

– for SCADA or electronic level control, refer to model 106-2SC-PCO / 206-2SC-PCO Dual Solenoid Control Valve
