- 4900 Series' Air Seperator

The 4900 Series' integral PALL ring technology has been proven in countless European installations. PALL rings are used in the processing industry to mix gases with, or separate gases from liquids. The use of PALL rings in hydronic air separation is so unique, it's patented. By applying PALL ring technology to air and dirt separation, the 4900 Series will:

• Remove microbubbles as small as 18 X 10-6m from the system;
• Remove air which has dissolved in the system's water;
• Remove air from places where an air vent cannot be installed;
• Remove and separate solid particles from the flow.

Sizes from 2" to 16"

- AC Series Inline Air Separator

2"-20" Connection Size Air Control Featuring: ASME 125# construction, Stainless steel removable strainer, 375° F maximum operating temperature, Larger sizes require less space than tangential designs, Optional higher working pressures, Available with flanged, grooved or NPT connections in smaller sizes.

- Accu-Flo Balancing Valve

The Taco Accu-Flo Balancing Valve combines superior engineering and design, precision machining and 100% factory testing to ensure the highest quality fixed port Venturi balancing valve on the market today. It features: Accuracy 4 - 5 times greater than variable orifice balancing valves Flow measurement independent of stem and ball position Ability to read nameplate setting not required to determine flow Tamper-resistant memory stop for accurate resetting Positive shut-off Ability to read low flows Sizes range from ½" to 4" with connections available in sweat, NPT and flanged.

- Expansion Tanks

In Taco "CA," "CBX," "PAX" and "CX" Series Expansion Tanks, the air is held captive on the shell side with all expanded fluid being directed into the bladder (CA, CBX and PAX Series) or diaphragm (CX Series) chamber. This permanent separation allows the tank to be precharged to the minimum system operating pressure (Pf) eliminating the need for many gallons of charge water to compress an atmospheric condition to the system requirements. The expanded fluid in the bladder or diaphragm chamber compresses the precharge to the maximum system pressure (PO) which then pushes the fluid back into the system as it contracts. No absorption can take place during the system cycle. Properly sized, selected and located air separation and removal components can provide a stable, tight and closed hydronic system. In most properly sized "CA" systems the tank size can be reduced by up to 80% when compared to the old style plan steel tanks. Sizes range from 7.8 gallon tank volume to 2640 gallon tank volume.

- "Plus One" Multi-Purpose Valve

Available in Sizes 1-1/2" through 10", the Taco Multi-Purpose Valve combines a shut-off valve, balancing valve, check valve and metering valve within one body and offers savings in space, hardware cost and labor. It features:

• Horizontal or vertical installation
• Dual "O" ring seal
• Bronze fitted construction
• Bubble tight shut-off
• Plug type flow control
• Memory stops
• Pointer and scale
• Back seated stem
• Easily removed spherical brass clapper
• No lubrication required
• Shrader valve metering connections

- SD Series Suction Diffuser

The Taco "SD" Series Suction Diffuser has numerous features built into one unit that provides the optimum flow and protection for the pump. The Suction Diffuser is available in cast iron or fabricated steel construction (consult Taco Fabricated Steel Suction Diffuser Submittal Data Sheet for information concerning the large fabricated steel units). The Cast iron units consist of 15 models, and are available in sizes from 2" X 1-½" through 10" X 8". A straight version is also available.

- Vortech Air Separator(™)

The Taco Vortech Air Separator(™) is designed to provide an enhanced level of air removal in hydronic heating, cooling or combination systems. Air is quickly and effectively separated and vented through a factory installed Taco 418 ¾" Hy-Vent. The Taco Vortech Air Separator(™) uses a tangential design to create a chamber of swirling water and air in which a low pressure area forms in the center. Combined with the Bubble Breaker Cartridge and a downward direction change in the flow of the water before exiting, air is quickly and effectively released upward and out through the Taco 418 ¾" Hy-Vent. Sizes range from ¾" NPT to 2" NPT.
