The Danfoss 032U1068 spare parts kit is the engineered solution for restoring the high-performance sealing and actuation of EV220B 12 servo-operated solenoid valves. This comprehensive service kit is specifically designed for Normally Closed (NC) configurations, featuring a reinforced EPDM diaphragm optimized for critical media like hot water and low-pressure steam. By utilizing the 032U1068 armature set, technicians ensure a drop-in internal overhaul that corrects common failure points such as leaking, failure to close, or sluggish response due to mineral build-up or rubber fatigue. Built for durability in demanding HVACR environments, this kit provides a brass armature and a self-cleaning coaxial pilot filter to protect the pilot system from particulate debris. The EPDM seal material is capable of handling temperatures from -30°C up to 140°C, making it a versatile choice for brine and heating systems alike. Professionals rely on this Danfoss maintenance kit to maintain the water hammer damped closing characteristic of the EV220B series, ensuring long-term system stability and preventing localized pressure spikes during high-cycle operation. Key Benefits for Technicians Full System Restoration: Replaces the diaphragm, armature, spring, and O-rings to return the valve to factory-spec pressure and flow efficiency. Extreme Temperature Range: High-grade EPDM seals support media temperatures between -30°C and 140°C, suitable for steam and cooling applications. Debris Resistance: Features a self-cleaning pilot filter that mitigates the risk of orifice blockage in water-based systems. Damped Closing Performance: Formulated to maintain the natural water hammer protection inherent in the Danfoss EV220B 15-50 modular program. Common Questions & Troubleshooting What is included in the Danfoss 032U1068 kit? The kit contains a complete armature assembly with a valve plate and spring, a new EPDM diaphragm, an O-ring for the armature tube, and the locking button/nut for the coil. How do I fix a solenoid valve that stays open? This kit resolves "stuck open" issues by replacing the armature spring and clearing the pilot orifice, ensuring the pressure differential can rebuild across the diaphragm. Is this kit compatible with FKM-sealed valves? No, the 032U1068 is an EPDM version. For oil or high-temperature air, an FKM-specific Danfoss spare part should be used to ensure chemical compatibility.
