Belimo B341 Valve
The Belimo B341 is a high-performance 3-way characterized control valve designed for precise regulation in hydronic systems. Featuring a 1 1/2" NPT connection and a 46 Cv rating, this valve is engineered with a nickel-plated forged brass body and stainless steel ball and stem to withstand demanding chilled or hot water applications up to 250°F. Its unique A-port equal percentage flow characteristic, enabled by the integrated characterizing disc, ensures linear thermal output and prevents the control loop "hunting" common in standard ball valves. The B-port is modified to maintain constant common port flow, making it an ideal choice for air handling units, fan coil units, and bypass loops. This CCV (Characterized Control Valve) supports up to 60% glycol solutions and provides a zero-leakage seal (0% for A-AB) to maximize energy efficiency in both variable and constant flow systems.
Key Benefits
- Optimized Control Stability: The stainless steel characterizing disc provides an equal percentage flow characteristic comparable to globe valves, ensuring stable part-load performance.
- Durability and Material Integrity: Equipped with a stainless steel ball and stem and PTFE seats for superior chemical resistance and extended service life in HVACR environments.
- High Close-off Performance: Provides a 200 psi close-off pressure rating, ensuring reliable shut-off and preventing energy waste.
- Versatile Application: Suitable for a wide range of building automation systems (BAS) and compatible with both spring return and non-spring return Belimo actuators.
- Maintenance-Free Design: Self-cleaning ball action and robust EPDM O-rings reduce the need for field servicing.
Common Questions
Can the Belimo B341 be used for steam applications?
No, this valve is specifically rated for chilled or hot water and hydronic systems with up to 60% glycol. It is not designed for steam service.
Is this valve suitable for use as a changeover valve?
The B341 is designed for mixing or diverting control. It is not recommended for use as a dedicated changeover valve in 2-pipe systems where rapid, high-volume switching is required without modulation.
What is the maximum pressure rating for the valve body?
The forged brass body is rated for a maximum body pressure of 400 psi, though the differential close-off pressure is limited to 200 psi.
