Danfoss 042U1003 Spare Part Kits
The Danfoss 042U1003 is a specialized solenoid valve repair kit designed for EV220A 12-14 series valves utilizing EPDM gaskets. Engineered for HVACR fluid control, this spare part kit is critical for maintaining normally closed (NC) valve operations in systems carrying water, glycol, or low-pressure steam. The kit includes a precision-machined armature, high-resilience EPDM diaphragm, and necessary O-rings to restore factory-spec sealing performance. Professional technicians rely on these direct-replacement components to rectify internal leakage or actuator failure without requiring a full valve body replacement. The EPDM elastomer ensures chemical resistance and thermal stability, making it essential for commercial boiler feed and chilled water loop maintenance. Ensuring a proper seal at the valve seat prevents pressure drops and maintains system efficiency in demanding industrial environments.
Key Benefits for Technicians:- Optimized Sealing: High-grade EPDM rubber provides superior resistance to hot water and prevents bypass leakage.
- Direct OEM Fit: Specifically calibrated for the Danfoss EV220A series, ensuring precise plunger travel and seat alignment.
- Reduced Downtime: Contains all necessary internal wear parts to field-service 12mm to 14mm orifice valves quickly.
- Atmospheric Reliability: Designed to withstand the cycles of servo-operated solenoid valves in variable pressure applications.
Is the 042U1003 kit compatible with oil-based systems?
No, the EPDM seals in this kit are designed for water and glycol; petroleum-based fluids will cause the elastomer to swell and fail. Use FKM or NBR kits for oil applications.
When should the internal armature and diaphragm be replaced?
If the valve fails to close completely or exhibits a "humming" noise, the armature may be fouled or the diaphragm may have lost its elasticity, requiring a complete rebuild kit.
Does this kit work for both EV220A and EV220B models?
Standardization varies; this specific kit is optimized for the EV220A 12-14 frame size. Always verify the valve's code number before installation.
