Danfoss 018F0091 Tester

The Danfoss 018F0091 Blue Magnet Tester is a specialized diagnostic permanent magnet designed for HVACR technicians to manually actuate and troubleshoot solenoid valves without requiring an electrical power supply. This genuine Danfoss OEM accessory allows for immediate functional verification of valve internals, helping contractors distinguish between mechanical failure and electrical coil issues. By replacing the solenoid coil with this high-strength magnetic tool, you can confirm if a valve is stuck or operating correctly, making it critical for servicing EVR, AKV, and ICS refrigeration systems.

Built for the rigors of field use, the 018F0091 tester is a lightweight, compact solution that ensures technicians can perform rapid maintenance on liquid line solenoid valves and expansion valves. Its simple blue design is an industry standard for identifying Danfoss magnetic tools. Whether you are performing a pressure test or routine maintenance, this manual actuator provides the precision needed for industrial and commercial refrigeration diagnostics.

• Instant Actuation: Enables manual opening and closing of solenoid valves without wiring or power.
• Precise Diagnostics: Quickly identifies if a valve is mechanically seized or if the solenoid coil has failed.
• Broad Compatibility: Engineered for use with Danfoss EVR, AKV (10P/10PS), EVU, and EVUL valve ranges.
• Field Ready: Durable, permanent magnetic steel construction ensures long-term reliability in tool kits.
• Safety Focused: Allows for safe system testing during installation and servicing without live electrical exposure.

• How do I use this to test a solenoid valve? Simply remove the electrical coil from the valve stem and slide the Danfoss 018F0091 magnet over the armature. If the valve opens or closes as intended, the mechanical components are functional.
• Which valves is this compatible with? It is designed specifically for Danfoss solenoid valves including the EVR series and AKV electronic expansion valves.
• Does this require batteries for operation? No, this is a permanent magnet tool and does not require any external power or batteries.
