Belimo B351 Valve
The Belimo B351 is a high-performance 2" 3-way characterized control valve engineered for precision in hydronic HVAC systems. Featuring a 68 Cv rating and a robust nickel-plated forged brass body, this valve is designed to handle chilled or hot water up to a maximum temperature of 250°F and is compatible with glycol solutions up to 60%. The stainless steel ball and stem provide superior durability and chemical resistance, ensuring reliable operation in demanding building automation systems (BAS). Its unique flow characteristic includes an A-port equal percentage flow for precise linear heat output and a B-port modified for constant common port flow, making it ideal for mixing or diverting applications. With a 400 psi body pressure rating and a 200 psi close-off limit, the B351 ensures tight shut-off and stable control in variable or constant flow loops found in air handling units (AHUs) and unit ventilators.
Key Benefits- Precision Control: Features a Tefzel characterized disc to maintain equal percentage flow for stable temperature regulation.
- Industrial Durability: The stainless steel trim and PTFE seats offer excellent protection against scaling and wear.
- Zero Leakage: Optimized design provides 0% leakage from Port A to AB, enhancing overall system efficiency.
- High Compatibility: Operates seamlessly with Belimo ARB and AFRB series actuators for non-spring or spring return fail-safe requirements.
- Versatile Media Handling: Rated for high-temperature hydronic applications and high-concentration glycol mixtures.
What is the maximum pressure drop allowed for the Belimo B351?
The maximum differential pressure (delta P) for standard control applications is typically 30 psi, while the mechanical close-off pressure for this 2-inch model is rated at 200 psi.
Can this valve be used for steam applications?
No, the B351 series is specifically designed for chilled or hot water and glycol solutions. It is not rated for steam media.
Which port should be used for the bypass in a mixing application?
In a mixing configuration, Port B typically serves as the bypass port, featuring a modified flow characteristic to maintain constant total flow through the common Port AB.
