Belimo B219VS 3/4″ NPT 2-Way Ball Valve, 30 Cv, Bronze/SS, 280°F Max

Description

Belimo B219VS 2-Way Ball Valve Overview

The Belimo B219VS is a high-performance 2-way characterized ball valve engineered for demanding hydronic and steam HVAC applications. Featuring a 3/4″ NPT connection and a generous 30 Cv flow coefficient, this valve delivers precise flow control across a wide range of system types — from chilled water and hot water to steam service. Its modified equal percentage flow characteristic ensures smooth, stable modulation throughout the full stroke, making it an ideal match for Belimo actuators in variable-flow systems.

Key Features

• 3/4″ NPT end connections for easy installation into standard piping
• 30 Cv flow coefficient for high-capacity flow in compact pipe sizes
• 2-way configuration for on/off or modulating control
• Modified equal percentage flow characteristic for precise, stable modulation
• Durable bronze body construction for corrosion resistance in hydronic systems
• Stainless steel ball and stem for superior durability and long service life
• Rated for chilled water, hot water, and steam applications
• Maximum operating temperature of 280°F (138°C)
• Compatible with up to 60% glycol solution for freeze-protection applications

Application Suitability

The B219VS is designed for use in commercial and industrial HVAC systems where reliable flow control is critical. Its compatibility with chilled water, hot water (up to 280°F), and steam makes it a versatile choice for air handling units, fan coil units, heat exchangers, and terminal unit applications. The 60% glycol compatibility extends its usefulness to systems operating in cold climates or requiring freeze protection.
