Frequently asked questions
Common questions about Parker from 3G Electric.
What solenoid coil models do you stock for Parker valves?
Current inventory includes Parker solenoid coils ZH14, ZB09, and ZB14 variants. These are direct-replacement coils for Parker directional control valves and proportional valve bodies. ZH and ZB designations refer to different envelope sizes and mounting styles. Availability of voltage ratings (24V DC, 110V AC, 220V AC, 380V AC) varies by model. Contact us for specific coil part numbers and lead times; technical datasheets with electrical ratings and connector diagrams are provided upon request.
Can I use a Parker solenoid coil as a direct replacement in my existing hydraulic valve?
Yes, if the valve body is a Parker cartridge or directional control valve originally equipped with a Parker solenoid. Verify the coil model (ZH14, ZB09, etc.), voltage rating, duty type (continuous or intermittent), and connector type against your original part number. Mismatched envelope dimensions or voltage will cause installation or operational failure. Always cross-reference the valve mounting cavity dimensions and electrical supply specifications before ordering. We can assist with part verification.
What pressure and flow ranges do Parker hydraulic valves available support?
Parker proportional and directional control valves in our range typically operate at system pressures from 10 bar (pilot-operated circuits) to 280+ bar (industrial high-pressure applications), with rated flow capacities from 5 liters/min to 200+ liters/min depending on valve geometry and spool configuration. Specific ratings vary by model and cartridge type. Consult technical documentation or contact us for pressure-flow curves and NG (nominal flow) specifications for your application.
Are Parker solenoid coils suitable for continuous or intermittent duty?
Most Parker solenoid coils are rated for both continuous and intermittent duty, though thermal limits differ. Continuous-duty coils are designed to remain energized for extended periods without exceeding thermal thresholds; intermittent-duty coils tolerate higher current but must cycle with sufficient off-time for cooling. Duty rating is specified in product datasheets. High-frequency proportional valve solenoids have different thermal characteristics than on-off directional control solenoids. Verify duty class against your application's energization cycle.
What connector types are used on Parker solenoid coils, and do you supply lead assemblies?
Parker solenoid coils typically feature DIN 43650 (Form A, B, C), flying-lead terminals, or wet-mateable connectors depending on model and application. The ZH and ZB series support multiple connector options. We supply coil units with connector specifications; availability of pre-assembled lead harnesses or custom connectors should be confirmed at quotation. Standard DIN 43650 connectors are widely available as aftermarket options.
How do I verify Parker solenoid coil compatibility with my valve model?
Cross-reference your valve's part number with Parker's technical catalog or ISO 1219 valve schematic. Key verification steps: confirm the valve is a Parker-manufactured proportional or directional control valve, identify the solenoid cavity size (coil envelope: ZH, ZB, etc.), voltage rating and frequency (DC or AC), power rating in watts, and mounting style. Provide the complete valve part number to us for accurate solenoid coil matching. Original equipment schematic diagrams are the authoritative reference.
