Belimo B248 Ball Valve, 2″ NPT, 2-Way, 29 Cv, Equal Percentage Flow

Description

Overview

The Belimo B248 is a 2-inch NPT, 2-way ball valve engineered for reliable flow control in chilled water and hot water HVAC systems. With a 29 Cv flow coefficient and equal percentage flow characteristic, this valve delivers precise, proportional control across its full operating range — making it an ideal choice for variable-flow hydronic applications where accurate temperature regulation is critical.

Durable, Corrosion-Resistant Construction

Built to withstand demanding commercial and industrial environments, the B248 features a nickel-plated forged brass body paired with a stainless steel ball and stem. This combination provides excellent resistance to corrosion and wear, ensuring long service life in both chilled and hot water systems. The valve is rated for fluid temperatures up to 212°F (100°C) and is compatible with glycol solutions of up to 60% concentration, making it suitable for freeze-protection applications.
