The MCC POWERS 410 378 is a stem plate replacement component designed for the Powers Hydroguard 410 series thermostatic mixing valve. The stem plate serves as a critical internal part that supports valve stem alignment and sealing within the mixing valve body. This part is intended for use by licensed plumbers and mechanical contractors performing repair or preventive maintenance on Hydroguard 410 installations. It restores proper valve function without requiring full valve replacement, reducing downtime and material cost on service calls.
The Hydroguard 410 thermostatic mixing valve is commonly installed in commercial and institutional plumbing systems where tempered water delivery is required at sinks, showers, and healthcare fixtures. This stem plate is the appropriate replacement component when the original part shows wear, corrosion, or damage during a valve rebuild. It is suited for retrofit and repair work on existing Hydroguard 410 valve assemblies in both new construction and existing building stock.
Designed as a direct OEM-style replacement stem plate for the Powers Hydroguard 410 series thermostatic mixing valve.
Installation should be performed by a licensed plumber familiar with thermostatic mixing valve service procedures. Shut off the hot and cold water supply and relieve system pressure before disassembling the valve. Follow applicable plumbing codes, including IPC guidelines, when servicing tempered water systems. Inspect the valve body and adjacent components for wear before reinstalling the stem plate to ensure a complete and reliable repair.
