Caleffi 112001 Insulation Shell for 132552A

A pre-formed insulation shell for ½" and ¾" QuickSetter™ balancing valves, including the 132552A.

When designing or maintaining a hydronic heating or cooling system, proper insulation around balancing valves can be just as important as selecting the right valve. The Caleffi 112001 Insulation Shell is designed for use with Caleffi QuickSetter™ balancing valves, helping reduce heat transfer and protect the valve area from unwanted condensation.

For applications using the Caleffi 132552A QuickSetter™, the 112001 insulation shell provides a practical way to add insulation around the valve while maintaining access to the system's balancing components. Caleffi documentation identifies the 112001 as insulation for ½-inch and ¾-inch QuickSetter models, while an earlier Caleffi catalog specifically identifies 112001 as fitting the 132552A.

What Is the Caleffi 112001 Insulation Shell?

The Caleffi 112001 is a pre-formed insulation component designed for Caleffi QuickSetter balancing valves. It is part of Caleffi's Series 112 insulation products and has a 10 mm insulation thickness with a specified medium temperature range of 0–100°C.

The insulation is intended to help limit heat loss from hydronic components and, in suitable cooling applications, help reduce the potential for surface condensation.

Technical Specifications

Designed for QuickSetter™ Balancing Valves

The Caleffi 132552A QuickSetter™ is a ¾-inch FNPT adjustable static balancing valve featuring an integral flow meter. Caleffi lists a working flow range of 2.0–7.0 GPM, a maximum operating pressure of 150 psi, and a medium temperature range of 14–230°F.

The QuickSetter design allows technicians to adjust and verify system flow directly at the valve, making it useful in hydronic heating and cooling distribution systems. Adding the appropriate insulation helps address the thermal conditions around the valve without changing the basic balancing function of the QuickSetter.

Why Insulate a Hydronic Balancing Valve?

Uninsulated valves and piping can become points of unnecessary heat transfer within a hydronic system.

• Heating applications: insulation can help reduce heat loss to the surrounding environment.
• Cooling applications: properly insulated components can help limit surface condensation when operating conditions create temperatures below the surrounding air's dew point.

For contractors and facility maintenance teams, insulation can therefore be part of an overall approach to improving system efficiency and protecting surrounding equipment.

Key Features of the Caleffi 112001

Made for ½" and ¾" QuickSetter™ Valves

Current Caleffi documentation lists the 112001 for ½-inch and ¾-inch QuickSetter applications, and an earlier catalog ties it directly to the 132552A.

10 mm Insulation Thickness

The Series 112 shell provides 10 mm of insulation, rated for a 0–100°C medium temperature range.

Pre-Formed Design

The shell is pre-formed for the applicable QuickSetter valve rather than cut and wrapped on site.

Heating and Cooling Use

The insulation is intended for hydronic heating and cooling applications, helping limit heat loss on hot circuits and surface condensation on chilled circuits.

Caleffi 112001 and 132552A Compatibility

For customers specifically working with the 132552A, the relationship between these two part numbers is important. Caleffi's earlier U.S. catalog explicitly lists: 112001 – Insulation sleeve fits 132552A.

For installation-critical projects, KPaul Industrial recommends confirming the applicable valve revision and current Caleffi documentation before ordering.

Typical Applications

Commercial HVAC Systems

Insulation can help manage heat transfer around balancing components in commercial heating and cooling systems.

Hydronic Heating Systems

The insulation can help minimize unnecessary heat loss around the balancing valve.

Chilled Water Systems

Proper insulation around chilled-water components can help limit surface condensation under appropriate operating conditions.

Building Mechanical Rooms

The compact pre-formed design can be useful where organized insulation around valves and piping is required.

HVAC Retrofit Projects

The component can be considered when improving insulation on existing QuickSetter valve installations.

Installation Considerations

• Verify the valve model and connection size (the 132552A is a ¾" FNPT valve, 2.0–7.0 GPM)
• Confirm the correct Caleffi insulation part number
• Install according to Caleffi's instructions
• Keep adjustment, flow-meter visibility and service access clear
• Do not interfere with connected piping
• Account for operating temperature, humidity and continuity of the overall insulation

As with other hydronic insulation components, the effectiveness of condensation control depends on the system operating temperature, ambient conditions, humidity and the quality and continuity of the overall insulation system.

Why Choose Genuine Caleffi Components?

Using a Caleffi insulation component designed for the applicable QuickSetter valve helps ensure that the insulation solution is based on the manufacturer's intended product family rather than an improvised fit.

Caleffi's QuickSetter product line is designed for hydronic balancing applications and incorporates an integral flow meter that allows direct flow-rate readings during system balancing.
