Description
Overview
The Schneider Electric (Barber Colman) VB-9213-0-5-13 is a heavy-duty, two-way globe valve engineered for demanding commercial and industrial HVAC hydronic systems. Featuring a 3-inch flanged connection, this valve delivers precise flow control with an equal percentage flow characteristic, making it ideal for variable flow heating and cooling applications where accurate modulation is critical.
Key Features
- Valve type: Two-way globe valve with equal percentage flow characteristic
- Pipe size: 3 inches
- Connection type: Flanged
- Flow coefficient: 85 Cv for high-capacity flow applications
- Body material: Cast iron — ANSI Class 125 rated for durability and pressure performance
- Trim material: Brass for corrosion resistance and long service life
- Stem position: Stem Up Open (SUO) — valve opens as stem moves upward
- Brand lineage: Originally designed under the Barber Colman brand, now part of the Schneider Electric portfolio
Flow Characteristic
The equal percentage flow characteristic provides a non-linear response where equal increments of valve stem travel produce equal percentage changes in flow. This characteristic is well-suited for hydronic heating and cooling coil control, delivering stable and accurate modulation across a wide range of system operating conditions.
