McDonnell & Miller 172813 - 157S-M-MD High-Pressure Level Control

Reliable water level management is critical for high-pressure steam boiler safety, and the 157S-M-MD high-pressure level control provides dependable operation for demanding hydronic environments. Manufactured by McDonnell & Miller, this unit, identified by part number 172813, serves as a robust solution for maintaining consistent water levels to prevent dry firing and system failure.

This level control utilizes a precision float-actuated switch mechanism designed to handle the pressures found in industrial and commercial boiler systems. By sensing fluctuations in the water column, it triggers responsive switching to manage feed pumps or low-water cut-off functions, ensuring the boiler remains within safe operational parameters even under continuous, high-heat cycles.

Key System Performance Baselines:

• Precision sensing: Engineered for accurate liquid level monitoring in high-pressure applications.
• Durable architecture: Built with industrial-grade materials to withstand thermal stress and pressure variations.
• Operational longevity: Designed for reliability in demanding commercial and industrial steam settings.

⚠️ Application Profile: Primarily used in commercial and industrial steam boilers, high-pressure condensate return systems, and heavy-duty hydronic boiler assemblies where automatic level maintenance is required for safety and efficiency.
