Belimo B208 Vave

The Belimo B208 is a professional-grade 1/2 inch 2-way characterized control valve engineered for precision flow control in hydronic systems. Featuring a 0.46 Cv rating and an equal percentage flow characteristic, this valve utilizes a specialized disc to ensure linear heat transfer, preventing hunting and maintaining stable temperatures in chilled or hot water loops. Built with a nickel-plated forged brass body and a 316 stainless steel ball and stem, the B208 is designed to resist scale buildup and corrosion, even in systems utilizing up to 60% glycol solution. The NPT female threaded ends provide a secure, leak-proof connection for standard piping. Rated for media temperatures up to 212°F (100°C) and a maximum close-off pressure of 200 psi, this low-torque ball valve is compatible with LRB24 and TR series actuators, making it a reliable solution for air handling units and VAV reheat coils where precise modulation is critical.

• Optimized Flow Control: The integrated characterizing disc ensures equal percentage flow, matching the heat exchanger's output for superior loop stability.
• High-Durability Metallurgy: Stainless steel ball and stem prevent premature wear and chemical degradation compared to chrome-plated alternatives.
• Blow-out Proof Stem: Double O-ring design with EPDM seals provides maintenance-free reliability and prevents leaks under high-pressure cycles.
• Versatile Media Handling: Industrial-strength construction supports chilled water, hot water, and high-concentration glycol applications.

What actuators are compatible with the B208?
This 1/2" valve is designed to interface with Belimo LR, TR, and AR series actuators. Use an LRB24-SR for 2-10VDC proportional control or a TR24-3 for on/off or floating points.

Can this valve be used for steam applications?
No, the B208 is rated for a maximum fluid temperature of 212°F and is strictly for hydronic systems. For steam, a specialized high-temperature seat and seal configuration is required.

What is the maximum differential pressure for this valve?
The leakage-free close-off pressure is rated at 200 psi, while the maximum differential pressure for quiet, cavitation-free operation is 50 psi.
