Danfoss 032U1068 Kit

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.

• 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.

• 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.
