The SA series is an integral component of Eaton Vickers hydraulic valve systems, renowned globally for its industrial-grade protection, reliable electromagnetic performance, and convenient interchangeability.
SA-02-124515:
The SA-02-124515 is an Eaton Vickers SA series standard solenoid coil, designed for DG4V-3-60 series solenoid directional valves. It features a DIN U-type electrical connector, operates on 220V DC with 31W power consumption. The coil is constructed with high-quality materials for industrial-grade protection.
SA-02-124654:
The SA-02-124654 is an Eaton Vickers SA series encapsulated solenoid coil. It features a BS-type electrical connectorand operates on 120V 60Hz. The encapsulated design provides superior moisture, dust, and corrosion resistance for demanding industrial environments.
SA-02-124586:
The SA-02-124586 is an Eaton Vickers SA series solenoid coil, compatible with Eaton Vickers DG4V series solenoid directional valves. Specific voltage and power specifications may vary by batch—verify nameplate markings before installation.
SA series coils incorporate wet-armature solenoid design principles—moving parts operate submerged in hydraulic oil, providing lubrication and cushioning for quiet, long-life, and highly reliable operation.
As original Eaton Vickers solenoid coils, these products offer complete interchangeability within the same series and size, requiring no modifications to valve mounting interfaces or electrical connections.

Expert Maintenance Tips
1. Installation Guidelines
Verify coil model matches the valve body before installation: SA-02-124515 fits DG4V-3-60 series; other models fit DG4V series solenoid directional valves.
Clean the valve mounting surface and coil interface before installation to prevent foreign particles from affecting solenoid engagement.
Tighten coil nuts to manufacturer-recommended torque values—avoid over-tightening that may damage threads or under-tightening that may cause poor contact.
2. Electrical Connection Specifications
SA-02-124515 uses 220V DC supply; SA-02-124654 uses 120V 60Hz supply. Verify supply voltage matches coil rated voltage before connection.
Connector types: DIN U-type and BS-type. Ensure the connector is fully locked to achieve protection class.
Prolonged operation outside rated voltage range may shorten coil life.
3. Temperature Management
SA-02-124515 operating temperature range: 30–90°C. Ensure adequate heat dissipation around the valve body and coil in high-temperature environments.
Working medium: Hydraulic oil; nominal pressure: 25 MPa.
4. Periodic Maintenance Inspection
Inspect coil housing for cracks, discoloration, or overheating signs every 2,000 operating hours or at least annually.
Check electrical connectors for looseness, oxidation, or moisture ingress.
If valve response lag or reduced solenoid force is observed, first verify supply voltage is within rated range, then check coil resistance (open or short circuits require replacement).
Coils can be replaced without disturbing hydraulic connections—service directly on the valve body.
SA series coils follow Eaton Vickers’ unified interchangeability standards—same-series, same-specification coils are directly interchangeable.
