Eclipse 501221 Valve
The Eclipse 501221 Valve is a high-performance 3-inch NPT manual butterfly valve engineered specifically for air and gas flow control within industrial combustion systems. As a full port butterfly valve, the 112BV-B model features a beveled disc design with a 75-degree rotation, ensuring a high flow coefficient (Cv) of 457 to minimize pressure drop across the line. Constructed with a powder-coated cast iron body and a carbon steel disc, this valve is built for durability in demanding HVACR and process heating environments. The zinc-plated steel shaft and Buna-N shaft packing seal provide reliable operation and resistance to common industrial media. Technicians should note that while these valves excel at precision throttling and flow regulation, they are not intended for use as tight shut-off valves. This manual control unit integrates seamlessly into systems requiring consistent combustion air regulation or gas manifold pressure management, offering a rugged, field-proven solution for contractors focused on system efficiency and long-term performance.
Key Benefits- Full Port Design: Maximizes flow capacity and reduces turbulence, achieving a Cv of 457 for optimal system efficiency.
- Rugged Construction: Features a durable cast iron body and carbon steel disc designed to withstand industrial combustion environments.
- Precise Flow Control: The beveled disc and 75-degree rotation allow for granular manual adjustment of air and gas ratios.
- Reliable Sealing: Equipped with a Buna-N shaft packing seal to prevent external leakage during high-frequency operation.
- Ease of Integration: Standard 3" NPT threaded connections ensure straightforward installation in existing gas or air piping runs.
Can the Eclipse 501221 be used for bubble-tight shut-off?
No, this butterfly valve is designed specifically for flow control and regulation in combustion systems. It should not be used in applications where a 100% leak-proof shut-off is required.
What media is compatible with the 112BV-B model?
This valve is optimized for air and clean fuel gases common in industrial burners and HVACR combustion manifolds.
Does this valve support automatic actuation?
The 501221 is a manual control model. For automated requirements, a compatible automatic version or an optional crank arm assembly would be necessary for actuator integration.
