Belimo B253 Ball Valve
The Belimo B253 is a high-performance 2-way characterized control valve designed for precision modulation in large-scale HVAC systems. Featuring a 2-inch NPT female pipe thread connection and a generous 120 Cv flow coefficient, this unit is engineered for hot or chilled water applications, supporting up to a 60% glycol solution. The nickel-plated forged brass body housing a 304 stainless steel ball and stem ensures long-term resistance to corrosion and scaling in closed-loop systems. To maximize control stability, the B253 utilizes a specialized Acre-shape flow disc to provide an equal percentage flow characteristic, preventing hunting in the control loop. Rated for a fluid temperature range of 0°F to 212°F and a maximum close-off pressure of 200 psi, this stainless steel ball valve is a reliable solution for air handling units and heat exchangers requiring high-capacity flow control.
Key Benefits for Contractors
- Optimized Control: The equal percentage flow characteristic ensures linear heat output from the coil relative to the valve position.
- Durable Construction: Stainless steel ball and stem prevent premature wear from cavitation and chemical treatments.
- Leak Protection: EPDM o-rings and reinforced PTFE seats provide a zero-leakage rating (ANSI Class VI).
- High Flow Capacity: The 120 Cv rating allows for high volume throughput with minimal pressure drop across the 2-inch port.
- Actuator Compatibility: Designed for seamless integration with Belimo ARB and GRB series non-spring return and spring return actuators.
Common Questions
What is the maximum static pressure rating for the B253?
The valve body is rated to 400 psi, while the maximum close-off pressure is 200 psi.
Can this valve be field-repaired or re-packed?
Belimo 2-way ball valves utilize dual EPDM o-rings and are considered maintenance-free components that do not require packing adjustments.
Is the B253 suitable for steam applications?
No, this model is specifically rated for water and glycol solutions up to 212°F; it is not intended for steam service.
