Frequently Asked Questions
Q: What is the 24VDC solenoid EP21-24 and what does it control?
A: The EP21-24 is a 24VDC solenoid coil designed for Linde class 2 and class 3 electric lift truck applications. It controls hydraulic valve operations including lift, lower, tilt, and directional functions. The solenoid is rated for intermittent duty with 18W power consumption and features a flat bracket mount for panel installation.
Q: What are the electrical and physical specifications for the EP21-24 solenoid?
A: The EP21-24 operates at 24VDC nominal, consumes 18W during energization, and is rated for intermittent duty cycles. It has a KOSTAL M24x1 and M27x1 threaded connection for valve mounting, flat bracket mount for structural attachment, and M6x1.0 metric mounting bolts. The coil features thermoset encapsulated winding for moisture and vibration resistance.
Q: Which Linde electric lift truck models use the EP21-24 solenoid?
A: The EP21-24 is compatible with Linde class 2 and class 3 electric lift trucks. The original equipment manufacturer part number is LIEP21-24. This solenoid is also used in similar electric lift truck applications from Crown, Toyota, Raymond, Yale, and Hyster. Verify your truck model number and control system voltage before ordering.
Q: What does intermittent duty rating mean for the EP21-24 solenoid?
A: Intermittent duty means the solenoid is designed to cycle on and off with rest periods between activation. It cannot be energized continuously without risk of overheating. Typical intermittent duty cycles allow the coil to cool between operations. Do not operate the EP21-24 in continuous duty applications or lifespan will be severely reduced.
Q: What materials and construction methods are used in the EP21-24 solenoid coil?
A: The EP21-24 features a thermoset encapsulated winding that provides excellent moisture resistance, vibration dampening, and mechanical protection. The encapsulation prevents coil short circuits from water intrusion and mechanical damage. The KOSTAL threaded connection is industry standard for reliable valve interface. This construction ensures durability in warehouse and material handling environments.
Q: How long does the EP21-24 solenoid typically last and what causes failure?
A: With proper operation, the EP21-24 typically lasts 5 to 10 years. Failure modes include burned coil windings from continuous energization or voltage spikes, corroded KOSTAL connections from moisture, and mechanical wear from vibration. Replace the solenoid if it fails to energize, hums continuously, or shows signs of coil burn. Verify power supply voltage is correct to prevent premature failure.
