Emerson Alco 045072 Repair Kit

The Emerson Alco 045072 Repair Kit (industry designation K-1231) is a heavy-duty service solution designed for Alco 210CA series 2-way solenoid valves with 3/4-inch pipe connections. As a veteran-grade rebuild package, it includes a Buna-N seat and all critical internal moving parts—such as the plunger assembly, diaphragm, and stainless steel springs—to restore "as-new" sealing performance. Because the 210CA is a pilot-operated valve, maintaining the integrity of the elastomer is essential for preventing common HVACR refrigeration leak issues and ensuring the valve shifts correctly under MOPD (Maximum Operating Pressure Differential) conditions.

When performing a solenoid valve rebuild, this kit resolves mechanical failures like stuck valves or coil burnout caused by internal obstructions. This kit is specifically engineered for mid-sized commercial systems where Buna-N compatibility with standard refrigerants and oils is required. Professionals should verify the PCN 045072 to ensure a proper fit for the 3/4" orifice 210CA valve body and avoid the downtime associated with faulty solenoid valve troubleshooting.

• OEM Precision: Specifically designed for the Alco 210CA 3/4" series to ensure a drop-in fit.
• Enhanced Sealing: Features a high-grade Buna-N seat for reliable shut-off in temperature-controlled environments.
• Operational Reliability: Includes a new plunger assembly and core spring to prevent solenoid humming or rattling.
• Comprehensive Maintenance: Replaces all wear-prone internal elastomers and moving parts effectively.

• Does this kit work for 1" 210CA valves? No, while the series is similar, the 1" valves require the K-1177 (PCN 038934). This K-1231 is strictly for 3/4" pipe sizes.
• When should I choose Buna-N over Ethylene Propylene seats? Buna-N is the standard for most air and water applications; however, for specific HVACR chemical compatibility or steam, verify your medium against the Emerson technical datasheet.
• Why did my coil burn out before using the kit? A stuck plunger or debris in the enclosing tube can cause the coil to overheat; always clean the valve body thoroughly when installing the 045072 repair kit.
