Belimo B219VS Valve

The Belimo B219VS is a high-performance 3/4 inch NPT 2-way characterizable control valve designed for precision fluid control in demanding HVAC and steam applications. Engineered with a bronze body and a 316 stainless steel ball and stem, this 30 Cv ball valve provides superior durability when handling chilled water, hot water, or low-pressure steam up to 15 psi. Utilizing a modified equal percentage flow characteristic, the B219VS ensures linear heat output for optimized coil performance. The TEFZEL characterized disc enables stable control at low flow rates, preventing hunting in hydronic systems. Compatible with a variety of Belimo rotary actuators, this valve supports up to 60% glycol solutions and can withstand temperatures up to 280°F. For contractors, the B219VS offers a reliable solution for modulating control in air handling units and terminal equipment where bubble-tight shut-off and corrosion resistance are non-negotiable requirements.

• Enhanced Durability: The stainless steel ball and stem prevent pitting and corrosion in high-temperature hydronic heating and cooling loops.
• Precise Flow Control: Modified equal percentage design delivers consistent thermal output, improving system efficiency and comfort.
• High Temperature Rating: Capable of managing media temperatures up to 280°F, making it suitable for low-pressure steam and high-temp hot water.
• Reduced Leakage: Industry-leading design provides 0% leakage, ensuring system pressure stability and energy conservation.
• Versatile Media Compatibility: Rated for use with water/glycol mixtures up to 60%, ideal for systems requiring freeze protection.

What is the maximum pressure rating for steam applications using the B219VS?
The Belimo B219VS is rated for low-pressure steam applications up to a maximum of 15 psi, provided the media temperature does not exceed 280°F.

Can this valve be used in an open-loop system?
Yes, the stainless steel trim makes the B219VS more resistant to oxidation compared to standard chrome-plated brass, though water chemistry should always be maintained.

Which actuators are compatible with the B219VS ball valve?
This 3/4 inch valve is compatible with Belimo LR, AR, and KR series actuators, depending on the torque and fail-safe requirements of your specific control application.
