McDonnell & Miller 341600 Valve and Strainer Assembly

The McDonnell & Miller 341600, also known as the SA47-101-102 Valve and Strainer Assembly, is a critical replacement component designed for Series 47, 247, and 847 mechanical water feeders. This professional-grade kit includes a high-performance valve, a modular cartridge, and a strainer with a heavy-duty basket in its own housing. To ensure consistent boiler water level control, the assembly prevents debris from compromising the valve seat, a common cause of flooding or feeder malfunction. For veteran technicians, this assembly simplifies field repairs by integrating multiple wear-prone components into a single unit. It is compatible with 47-2 and 247-2 variants and features hex port valve architecture for reliable seating and flow regulation. Using a 13/16-inch socket for the cartridge and a 1/2-inch wrench for the strainer bolts, installers can restore low water cut-off and automated makeup water functionality without replacing the entire feeder body, minimizing downtime on steam heating systems.

• Universal Compatibility: Engineered specifically for Series 47, 247, and 847 water feeders, ensuring a precise fit without field modifications.
• Debris Protection: The integrated strainer basket captures scale and sediment before they reach the valve, preventing common seat leakage and boiler flooding issues.
• Service Efficiency: Combines the valve, cartridge, and strainer into one part number (341600), streamlining inventory and on-site maintenance.
• Enhanced Flow Control: Features a hex port design that provides stable modulation and consistent water makeup for residential and commercial steam boilers.

Is the SA47-101-102 compatible with Series 51 or 851 feeders?
No, this specific assembly is designed for the 47, 247, and 847 series. For Series 51 or 851, the gray cartridge and corresponding valve assembly must be used to ensure proper flow rates and pressure ratings.

What tools are required for installing the 341600 valve assembly?
You will need a 13/16" (21mm) socket wrench for the cartridge and a 1/2" (13mm) wrench for the four hex-head bolts securing the strainer housing. Do not over-tighten the cartridge beyond 2 ft-lb.

My boiler is flooding after I installed a new feeder; will this kit fix it?
Flooding is often caused by a fouled valve seat or debris stuck in the assembly. Replacing the entire 341600 valve and strainer kit clears the path and provides a fresh sealing surface, resolving most flooding issues related to the feeder unit.
