The Caleffi CBN130900 is a pre-formed insulation shell sized for the 2" Flo-Set 130 series fixed orifice balancing valve (130900A). The closed cell expanded PE-X shell wraps the valve body to minimize heat loss in heating service and eliminate surface condensation in chilled water service, while leaving the adjustment knob and pressure test ports accessible.
Best For
- Chilled water circuits where bare valve bodies would condense and drip
- Hydronic heating circuits where balancing valves would otherwise be uninsulated
- Meeting project specifications requiring insulated valve bodies
Key Features
Exact-Fit Molding
Pre-formed to the 2" 130 series body, closing fully around the valve with no cutting or taping of pipe insulation.
Service Access Preserved
The adjustment knob and PT ports remain usable, so the circuit can be rebalanced or verified without stripping insulation.
Condensation Control
Closed cell expanded PE-X resists moisture absorption, preventing sweating on chilled water service.
Tool-Free Installation
The two-piece shell snaps over the installed valve in seconds, before or after commissioning.
