DYNALCO Product Lines We Repair
Our engineers are trained on the full DYNALCO product range. Below are the major product families we service.
Pressure Control Modules (PCM Series)
Dynalco PCM modules manage hydraulic pressure regulation and load-sensing in mobile and industrial equipment. Common issues include seal degradation, spool stiction, pressure drift, and solenoid coil failures causing loss of pressure control or erratic system behavior.
Load-Check and Pilot-Operated Valves (LCV Series)
These valves prevent load drift and provide load-holding function in hydraulic systems. Typical faults include internal leakage, pilot line blockage, valve seat wear, and spring relaxation leading to reduced holding pressure and equipment drift.
Proportional Solenoid Valve Assemblies (PSV Series)
Dynalco PSV assemblies provide proportional flow control and directional switching. Common repair issues involve coil insulation breakdown, armature stiction, spool wear, electrical connector corrosion, and electronics card failure.
Electronic Control Card Assemblies (ECA Series)
Embedded control cards for Dynalco systems featuring analog and digital I/O, proportional valve drivers, and integrated diagnostics. Failures include capacitor degradation, relay contact wear, driver IC burnout, and firmware issues causing control loss.
Pressure Switch Modules (PSW Series)
Dynalco pressure switches and transducers for system monitoring and interlock control. Repair needs include diaphragm rupture, electrical contact corrosion, dead-band drift, and transducer output calibration errors.
Integrated Hydraulic Logic Blocks (IHB Series)
Compact integrated valve manifolds combining pressure control, load-check, and pilot logic in single blocks. Common faults involve internal cavity blockage, cavity seal leakage, pilot line cross-leakage, and valve spool binding.

Common DYNALCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNALCO equipment arriving at our workshop.
- ✓Pressure control module spool stiction and drift — Hydraulic fluid contamination and varnish buildup in Dynalco PCM spool cavities causes friction and loss of smooth pressure regulation. Extended operation without fluid changes exacerbates the issue, leading to erratic pressure spikes or loss of load-sensing control.
- ✓Solenoid coil insulation breakdown in PSV assemblies — Moisture ingress, thermal cycling, and vibration cause insulation degradation in Dynalco proportional solenoid coils. This leads to phase shifts, reduced coil force, intermittent valve response, or complete electrical failure and proportional control loss.
- ✓Electronic control card capacitor failure and relay stiction — Dynalco ECA modules experience capacitor dry-out and aluminum electrolytic failure in high-temperature and high-vibration environments common in Indian crushing plants and heavy machinery. Relay contacts weld or oxidize, preventing proportional valve command execution.
- ✓Load-check valve pilot blockage and loss of load holding — Particulate contamination in Dynalco LCV pilot lines causes blockage, preventing pilot pressure build-up. This leads to load drift, equipment sagging, and safety hazards in hydraulic excavators, cranes, and material handlers used across Indian construction sites.
- ✓Pressure transducer zero-offset drift and calibration loss — Dynalco PSW transducer diaphragm relaxation, zero-reference degradation, and electronics aging cause output signal drift typically 5-15% over 2-3 years. This leads to system pressure misreading, safety interlocks failure, and process control errors in Indian textile mills and rubber extrusion plants.
- ✓Integrated hydraulic logic block cavity seal leakage and cross-port mixing — Dynalco IHB manifold internal cavity seals degrade due to hydraulic fluid oxidation, thermal cycling, and improper fluid selection. Pilot line cross-leakage between cavities causes pilot pressure loss and erratic valve switching or load-holding failure.

We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat with same-day diagnostic turnaround.
What is the typical turnaround time for Dynalco pressure control module repair?+
For Dynalco PCM module repairs, turnaround is typically 3-5 working days depending on fault severity. We perform spool cleaning, seal replacement, pressure calibration, and full system pressure ramp testing. Complex cases requiring spool grinding or cavity re-machining may extend to 7-10 days. We provide interim loaner units for critical production environments to minimize downtime.
Can Synchronics recalibrate Dynalco PSW pressure switches and transducers to customer specifications?+
Yes. Synchronics performs full 4-point pressure transducer calibration and pressure switch dead-band adjustment using certified pressure calibrators traceable to NIST standards. We customize Dynalco PSW modules to exact customer pressure set-points, dead-band windows, and hysteresis limits. All calibrations are documented with certificates and complete calibration curves. We also modify switch voltage outputs and analog signal ranges per customer control system requirements.
Do you repair Dynalco electronic control card assemblies that show proportional valve command errors?+
Yes. Synchronics performs comprehensive ECA diagnostics including coil driver IC testing, analog output linearity verification, relay contact resistance measurement, and proportional solenoid command signal analysis. We repair failed driver ICs, replace relay banks, upgrade capacitor banks, and reprogram firmware if required. Post-repair, all ECA units undergo dynamic proportional valve command testing to ensure proper ramp response and signal stability.
What warranty do you provide on Dynalco repair services?+
All Synchronics Dynalco repairs come with a 12-month comprehensive warranty covering parts and labor. We also offer extended warranties up to 24 months for critical customer applications. In case of repeat failure within warranty period, we provide immediate no-charge repair or full refund. We also maintain spare component inventory for all major Dynalco product lines to expedite warranty claims and customer replacements.
How do I send my DYNALCO unit for repair?+

What is the cost of repairing a DYNALCO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DYNALCO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
