McDonnell & Miller 194-B-1 Replacement Casting

The McDonnell & Miller 194-B-1 Replacement Casting is a critical structural component designed specifically for the Series 194 Combination Low Water Cut-Off and Pump Controller. As a veteran-preferred boiler replacement part, this heavy-duty water column casting features the standard 1-1/4 inch NPT steam equalizing tappings and integrated ports for gauge glass and tri-cock sets. Engineered for high-pressure environments, it maintains structural integrity up to a maximum pressure of 250 PSI, ensuring reliable performance in commercial and industrial steam systems. This OEM McDonnell & Miller casting allows technicians to rebuild existing water level control systems without the cost of a complete unit replacement, provided the internal 94-HD head mechanism and float assembly remain functional. Proper installation requires verifying alignment with the Series 194-B alternate tapping configuration to ensure accurate low water cut-off sensing and pump control cycling.

Key Benefits

• Direct Compatibility: Precision-cast to fit Series 194 and 194-B water level controllers, ensuring leak-free integration with legacy piping.
• Industrial Durability: Engineered to withstand 250 PSI maximum steam pressure, meeting the rigors of high-demand boiler rooms.
• Integrated Tappings: Features professional-grade ports for gauge glass and tri-cock installation, simplifying the water column setup.
• High-Volume Steam Capacity: Designed for boilers of any steaming capacity requiring robust 1-1/4" NPT connections.

Common Questions

• Does this include the internal float or switch mechanism? No, the 194-B-1 is the casting (body) only. Internal components like the 94-HD head mechanism or No. 5 switch must be purchased separately if needed.
• What is the difference between this and the standard 194 casting? The "B" designation typically refers to an alternate tapping configuration. Always verify your center-to-center dimensions for gauge glass and equalizing lines before purchase.
• Can this be used on high-pressure steam boilers? Yes, this casting is rated for high-pressure steam applications up to 250 PSI, making it suitable for industrial process boilers.
