TT CONTROL HYDAC INTERNATIONAL Equipment We Repair — By Category
TT CONTROL HYDAC INTERNATIONAL Product Lines We Repair
Our engineers are trained on the full TT CONTROL HYDAC INTERNATIONAL product range. Below are the major product families we service.
HYDAC Proportional Directional Control Valves
Electronically controlled proportional spool valves for precise flow and pressure regulation in hydraulic circuits. Common faults include solenoid coil failure, spool stiction, and proportional amplifier card malfunction affecting flow accuracy.
HYDAC Electronic Pilot Units (EPU)
Compact integrated electronic control units that replace traditional pilot pressure systems. Repair needs often involve logic card failures, analog input circuit degradation, and CAN bus communication errors.
HYDAC Proportional Amplifier Cards
Signal conditioning and power amplification cards for proportional solenoid coil actuation. Typical failures include capacitor degradation, mosfet burnout, and reference voltage drift causing erratic valve response.
HYDAC Poppet Logic Valve Blocks
Integrated sandwich-mounted valve stacks with electronic feedback for pressure and directional control. Faults include spool wear, cavity sealing degradation, and integrated electronics intermittent operation.
HYDAC CAN-Bus Interface Modules
Communication gateways for networked hydraulic systems using CANopen or J1939 protocols. Common issues are termination resistor failure, message buffer overflows, and node ID conflicts in multi-unit installations.

Common TT CONTROL HYDAC INTERNATIONAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TT CONTROL HYDAC INTERNATIONAL equipment arriving at our workshop.
- ✓Solenoid coil intermittent actuation failure — HYDAC proportional solenoid coils experience thermal stress and moisture ingress in humid Indian factory environments. Degraded insulation and wire fatigue in the electromagnet lead to erratic valve response or no spool movement.
- ✓Proportional amplifier card reference voltage drift — HYDAC amplifier reference IC degradation and aged filter capacitors cause the command signal reference to drift. This results in incorrect spool positioning, flow mismatch, and poor valve linearity in automotive press applications.
- ✓CAN-bus communication node timeout errors — HYDAC CTM modules experience CAN termination resistor failure or corrosion in multi-node hydraulic networks. Message arbitration delays cause system-wide control loss in coordinated injection moulding lines.
- ✓Spool stiction and slow valve response — HYDAC proportional directional valve spools develop stiction due to contaminated hydraulic fluid and corrosion in pilot passages. This causes sluggish directional changes critical in precision machine tool applications.
- ✓Pilot pressure feedback error signal intermittent — HYDAC pressure transducers and feedback signal conditioning circuits suffer from solder joint cracks and connector corrosion. Intermittent analog signal loss causes proportional valve instability in closed-loop control systems.
- ✓Proportional valve spool wear and cavity leakage — High-pressure HYDAC proportional valves in Indian foundries and forging plants experience abrasive particle contamination and micro-erosion. Spool clearances exceed tolerance causing internal leakage and reduced system pressure response.

Frequently Asked Questions — TT CONTROL HYDAC INTERNATIONAL Repairs
Do you repair TT CONTROL HYDAC INTERNATIONAL equipment anywhere in India?+
Yes. Synchronics is an authorized repair facility for the complete HYDAC product range across all of India. We offer PAN India door pickup from major metros including Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, and Ahmedabad. All repairs are performed at our Vadodara facility with guaranteed same-day diagnostics for critical downtime situations. We maintain genuine HYDAC spare parts inventory for rapid turnaround.
Can Synchronics repair HYDAC proportional valve electronics in my automotive plant?+
Absolutely. Our engineers have specialized expertise in HYDAC proportional directional control valves, amplifier cards, and electronic pilot units used in automotive press lines and assembly robots. We perform component-level repairs on solenoid drivers, proportional amplifiers, and pressure feedback circuits. We also carry genuine HYDAC replacement valve cartridges and can test repaired assemblies on our flow rig to verify factory specifications before installation.
What is the turnaround time for HYDAC proportional amplifier repair?+
Turnaround depends on fault complexity. Simple amplifier card recalibration and capacitor replacement typically takes 2-3 working days. Complex failures involving reference IC replacement or firmware reprogramming may take 4-5 days. Synchronics offers expedited 24-hour service for critical customer orders. We provide same-day preliminary diagnostics and cost estimates for all HYDAC amplifier cards.
Do you have expertise with HYDAC CAN-bus and networked hydraulic systems?+
Yes. Many Indian machine builders now use HYDAC CTM-01 and CTM-02 CAN-bus modules for integrated hydraulic control networks. Synchronics engineers are proficient in CANopen and J1939 protocol diagnostics, message arbitration, and node configuration. We perform network-wide communication testing and provide detailed fault reports identifying problem nodes or termination issues.
Can you supply genuine HYDAC spare parts or only repair services?+
Synchronics provides both repair services and genuine HYDAC spare parts sourcing through our authorized distributor relationships. Common spare parts like solenoid coils, proportional amplifier cards, pilot stage cartridges, and pressure transducers are typically in stock in Vadodara. We can also expedite international HYDAC parts through our supply chain for non-standard or obsolete components.
How do I send my TT CONTROL HYDAC INTERNATIONAL unit for repair?+
