Expert Hitran proportional valve and servo system repair across all Indian industrial sectors.
HITRAN CORPORATION Product Lines We Repair
Our engineers are trained on the full HITRAN CORPORATION product range. Below are the major product families we service.
PV Series Proportional Valves
Proportional directional control valves with integrated electronics for flow and pressure modulation. Common failures include solenoid coil burnout from contaminated fluid, spool stiction from varnish buildup, and loss of null position due to electrical drift.
SV Series Servo Valves
High-performance servo valves for precision motion control in test stands and production equipment. Typical repair issues include pilot stage erosion, nozzle-flapper assembly wear, and electronic feedback amplifier drift causing control instability.
Pilot Operated Check Valves (POCV)
Load-holding and pilot-operated check assemblies used in multi-axis systems. Failures stem from internal seal degradation, poppet wear, and pilot line blockage reducing pilot ratio efficiency.
Integrated Electro-Hydraulic Manifolds
Complete manifold blocks combining proportional valves, pressure regulators, and cartridge logic. Complex failures include cross-leakage between cavities, electronic module corrosion, and solenoid-to-spool synchronization loss.
Control Electronics and Amplifiers
Proportional and servo amplifier cards, pulse width modulation (PWM) controllers, and feedback signal processors. Common faults include capacitor failure from thermal stress, transistor burnout from transient spikes, and signal conditioning errors.

Common HITRAN CORPORATION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HITRAN CORPORATION equipment arriving at our workshop.
- ✓Solenoid coil burnout and open circuits — Contaminated hydraulic fluid ingress into solenoid coil windings, moisture absorption causing insulation breakdown, or sustained overvoltage spikes during proportional valve modulation. Indian plants with inadequate fluid filtration and poor electrical grounding are particularly vulnerable.
- ✓Spool stiction and loss of proportional response — Varnish and lacquer buildup on the spool from degraded hydraulic fluid or inadequate filtration. Spool sticks mid-stroke, preventing smooth proportional control and causing erratic system behavior in closed-loop applications.
- ✓Nozzle-flapper erosion in servo valves — Cavitation and high-velocity impingement of contaminated fluid across pilot stage orifices in Hitran SV series valves. Erosion widens orifice clearance, degrading pressure gain and frequency response in feedback control loops.
- ✓Pilot-operated check valve load-holding failure — Internal poppet seat wear, seal degradation from aged elastomers, or pilot line blockage reducing pilot pressure ratio. Load drifts or collapses under sustained pressure, causing equipment malfunction or safety hazards in machine tools and test stands.
- ✓Amplifier capacitor failures and power supply dropout — Aluminum electrolytic capacitors aging under thermal cycling, inrush current surges during system startup, or inadequate thermal management in Hitran PA and PWM amplifier modules mounted in hot machinery enclosures.
- ✓Cross-port leakage in manifold cavity interconnects — Erosion of seal surfaces in cavity interconnect bores, manufacturing micro-porosity, or thermal cycling stress cracking internal passages in integrated Hitran electro-hydraulic manifolds. Internal leakage bypasses proportional control and reduces system stiffness.

Frequently Asked Questions — HITRAN CORPORATION Repairs
Do you repair Hitran Corporation equipment anywhere in India?+
Yes. Synchronics repairs the complete Hitran product portfolio — proportional valves, servo valves, pilot-operated controls, electro-hydraulic manifold systems, and all associated amplifier electronics. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all major industrial cities. All equipment is repaired in our fully equipped Vadodara, Gujarat facility.
What is the typical turnaround time for Hitran proportional valve repair?+
Standard Hitran proportional valve repairs (solenoid replacement, spool cleaning, seal refurbishment) are completed within 5-7 working days after receipt. Complex integrated manifold repairs may require 10-14 days depending on cavity damage extent. Synchronics offers expedited repair options for critical production downtime situations — contact our team for same-day assessment.
How do you test Hitran servo valves before returning them?+
Synchronics performs full-envelope bench testing of all Hitran servo valve repairs. We measure frequency response up to the valve's rated bandwidth, confirm pressure gain and null bias within OEM specifications, and perform load-holding tests at rated flow and pressure. All testing data is documented and provided with your repaired unit.
Can Synchronics repair Hitran amplifier modules that show fault codes?+
Yes. We diagnose Hitran PA-2000, PA-3000, and PWM amplifier faults including output stage failure, reference voltage drift, feedback signal conditioning errors, and power supply issues. We have OEM-equivalent component stock and repair boards to component level. Failed units are restored to factory performance specifications with full functional and stress testing.
What should I do if my Hitran valve is leaking internally or losing load-holding pressure?+
Contact Synchronics immediately with your Hitran valve model, serial number, and failure description. We can often diagnose the issue over phone (seal degradation vs. seat wear vs. pilot line blockage). Send the unit for bench evaluation — most load-holding failures are repairable through seal replacement and precision re-lapping of poppet seats. We guarantee load-holding after repair.
How do I send my HITRAN CORPORATION unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HITRAN CORPORATION 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 HITRAN CORPORATION 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.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HITRAN CORPORATION unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
