Purchase now: Winner ES-08W-2A-15-Z-04 Cartridge Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics ES-08W-2A-15-Z-04, the industry-standard 2-Way Normally Closed (NC) Solenoid Spool Valve. This unit is the direct counterpart to the ‘2H’ model but operates with standard NC logic («2A»): it blocks flow when off and opens when energized. Like its sibling, it features the robust DIN 43650 Coil Connection («15»), making it the preferred choice for industrial hydraulic power units (HPUs) and high-end mobile machinery where weatherproofing is a concern.
Technical Specifications and Durability
Powered by a 12V DC coil («04»), this valve fits the universal Size 08 cavity. The spool design is balanced, meaning the force required to shift the valve does not change significantly with system pressure, allowing reliable operation up to 350 Bar. The Zinc Plated finish («Z») ensures durability. The DIN connector system allows for the integration of LED Indicator Plugs, giving maintenance teams immediate visual feedback on whether the valve is receiving power, speeding up troubleshooting significantly.

Maintenance: Troubleshooting Solenoids
Is it the coil or the valve? Expert Tip: If the valve fails to open, remove the DIN plug and measure the resistance across the two coil pins with a multimeter. A healthy 12V coil for a Size 08 valve should read between 6 and 10 Ohms (check specific datasheet). If it reads Infinite (Open circuit) or near Zero (Short circuit), the coil is dead. If the resistance is correct and you have 12V at the plug, the spool is physically jammed with debris.
Frequently Asked Questions (FAQs)
Q: What is the benefit of the DIN connector over wires?
A: Besides IP rating, the DIN connector puts no stress on the coil’s internal copper windings. Lead wires can be yanked, breaking the internal connection. DIN plugs are separate mechanical parts.
Q: Can I use this for water hydraulics?
A: No. The internal steel components will rust instantly. This is for mineral oil or synthetic hydraulic fluids only.
