Danfoss EVRA 10 Overhaul Kit 032F2202

Danfoss EVRA 10 Overhaul Kit – Part No. 032F2202

The Danfoss 032F2202 overhaul kit is an OEM-standard internal repair kit engineered for complete mechanical servicing of Danfoss EVRA 10 servo-operated solenoid valves. Used extensively across commercial marine reefer plants, cold-storage provisioning systems, and industrial ammonia (R717) refrigeration racks, the EVRA 10 valve regulates liquid, suction, and hot gas defrost lines.

Over time, rapid pressure cycling, particulate contamination, and thermal fluctuations cause wear on the pilot orifice seat, main piston PTFE sealing rings, and armature tube gaskets. Installing kit 032F2202 restores internal pressure tightness, eliminates pass-through leakage across the valve seat, and prevents external refrigerant loss to maintain plant coefficient of performance (COP) and marine safety standards.

Technical Specifications

Key Features

1. Complete Internal Overhaul: Includes the complete servo-piston assembly, pilot core armature, return springs, and seal set to renew internal operation without cutting out valve piping.
2. Ammonia & Halocarbon Resistant: Constructed with high-grade PTFE valve discs and oil-resistant elastomeric seals capable of withstanding pure anhydrous ammonia (R717) and synthetic compressor oils.
3. Tight Zero-Leak Seat Closure: Precision-machined pilot disc and main seating rings guarantee leak-tight shut-off under severe reverse-flow back-pressures up to rated limits.
4. Low Differential Actuation: Features calibrated return springs that allow full servo opening at minimum differential pressures as low as 0.05 bar (0.73 psi).
5. Direct Drop-In OEM Fitment: Machined to exact Danfoss factory tolerances to fit cast iron and nodular iron EVRA 10 valve bodies without modification.

Applications

• Marine Provision Refrigeration Plants: Fish storage, meat rooms, and vegetable cold rooms operating on R717, R404A, or R134a.
• Cargo Refrigeration Systems (Reefer Vessels): Deck cargo brine chillers, direct expansion hold evaporator circuits, and container refrigeration units.
• Industrial Cold Storage Facilities: Automated blast freezers, spiral freezers, and ice production plants.
• Compressor Package Unloading & Defrost: Hot gas defrost injection lines and liquid injection sub-cooling lines in commercial chiller packages.

Frequently Asked Questions

What are the main signs that an EVRA 10 solenoid valve needs an overhaul?

The three primary failure indicators are: (1) internal pass-through leakage (evaporator coil frosting or temperature dropping while coil is de-energized), (2) valve failing to open despite an energized coil due to a scored piston cylinder or blocked equalizing orifice, and (3) external gas leakage around the armature tube base gasket.

Can the 032F2202 overhaul kit be used on both Ammonia (R717) and Freon systems?

Yes. The materials inside the 032F2202 kit—including PTFE valve plates, chloroprene/synthetic O-rings, and stainless steel internals—are fully rated for pure anhydrous ammonia (R717) as well as common HFC, HCFC, and HFO refrigerants.

Does this kit include the replacement solenoid coil?

No. The 032F2202 is purely a mechanical internal service kit. If electrical burnout has occurred, replacement Danfoss 10W or 12W clip-on coils (e.g., 018F6701 for 230V AC) must be ordered separately.

What is the recommended bolt torque when reinstalling the EVRA 10 armature assembly?

The armature tube on the EVRA 10 should be tightened to a torque specification of 50 Nm (37 ft-lbs) to ensure a gas-tight seal on the lower housing gasket without distorting the internal pilot stroke guide.
