HANSEN Product Lines We Repair
Our engineers are trained on the full HANSEN product range. Below are the major product families we service.
Proportional Directional Control Valves
Hansen's NG series proportional valves regulate fluid flow and direction in sugar mills, textile machinery, and packaging lines. Common repairs include spool stiction from contamination, solenoid coil burnout from voltage transients, and valve manifold cracking under cyclic pressure stress.
Pressure Compensator and Pilot Valves
Hansen pressure reduction and load-check valves maintain precise system pressure in sugar crystallizers and chemical reactors. Failures include pilot cartridge erosion, adjusting screw drift causing pressure creep, and spring relaxation in high-temperature applications above 60°C.
Solenoid Actuator Assemblies
Hansen wet-pin and dry-pin solenoid spools control proportional valve switching in textile dyeing vats and sugar evaporators. Repair focuses on coil winding insulation breakdown, armature stiction from mineral deposit buildup, and connector corrosion in humid plant environments.
Electronic Valve Controllers (EVC)
Hansen embedded electronics for proportional valve modulation in feedback control loops. Common faults include capacitor swelling under 50°C ambient heat, signal conditioning amplifier drift, and relay contact pitting from high-frequency switching in servo applications.
Pneumatic Directional Control Solenoid Valves
Hansen air-operated and solenoid-pilot pneumatic valves in packaging, food processing, and automotive assembly lines. Failures include solenoid plunger seizure from rust in humid monsoon climates, pilot orifice blockage by airborne particulates, and diaphragm perforation.
Cartridge Valve Manifolds and Subplates
Hansen modular cartridge cavity blocks used in Indian sugar refineries, breweries, and food processing plants for integrated valve stacking. Issues include internal cavity corrosion, port face leakage from contaminated seals, and manifold porting blockage in glycerin or syrup applications.

Common HANSEN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HANSEN equipment arriving at our workshop.
- ✓Proportional spool stiction and sluggish response — Hansen proportional valves operating in sugar mills and textile dye vats accumulate mineral deposits and sludge on internal spool surfaces. High ambient temperature (45-55°C typical in Indian summer plants) causes viscosity breakdown of hydraulic oil, trapping contaminants in spool grooves and reducing sliding dynamics.
- ✓Solenoid coil open-circuit and no valve actuation — Hansen solenoid coils suffer insulation breakdown due to sustained 50-60°C ambient temperatures, moisture ingress from washdown environments in food processing plants, and voltage transient spikes from unshielded PLC wiring in Indian industrial installations. Copper winding corrosion accelerates failure in monsoon-prone coastal regions.
- ✓Pressure compensator drift and system overpressure — Hansen pressure compensator pilot cartridges experience erosion of metering edges from silicon particles in contaminated hydraulic fluid common in Indian foundries and cement plants. Adjusting screw creep under cyclic load and spring relaxation in 60+°C environments cause gradual pressure setpoint rise, leading to relief valve chatter and seal failures downstream.
- ✓Pilot solenoid hums but spool does not shift — Hansen spool control solenoids become energized but plungers stick in neutral due to rust accumulation on armature surfaces in humid sugar factories, or pilot pressure insufficient to overcome load-check cartridge cracking pressure. Contaminated pilot oil with varnish deposits further reduces pilot flow capacity.
- ✓Valve manifold internal leakage and slow actuator response — Hansen cartridge cavity manifolds develop internal port-face leakage when sealing surfaces are scratched by debris during installation, or when temperature cycling in Indian seasonal environments (10-50°C swings) causes sealant shrinkage. Glycerin and syrup applications in food processing accelerate polymer seal degradation.
- ✓Electronic valve controller signal loss and proportional valve lockout — Hansen EVC 100 series controllers fail when aluminum electrolytic capacitors in the power supply swell under sustained 45°C ambient temperatures in unventilated electrical enclosures. Signal conditioning amplifier gain drift from component aging causes proportional command signals to saturate, locking the valve at extreme positions.

Frequently Asked Questions — HANSEN Repairs
Do you repair Hansen equipment anywhere in India?+
Yes. Synchronics repairs the full Hansen product range — proportional valves, directional controls, solenoid actuators, electronic controllers, and cartridge manifolds. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Jaipur, and all other metros. All repairs are performed in our 180+ engineer facility in Vadodara, Gujarat with genuine Hansen components in stock.
How do I know if my Hansen proportional valve needs repair versus replacement?+
Synchronics performs free diagnostic testing of Hansen proportional valves. We measure spool response time, linearity of flow-control curve, and internal leakage using calibrated test benches. If response time exceeds 300ms, linearity deviates >5%, or leakage exceeds 2% of rated flow, repair (spool reclaiming, seal replacement) is typically 60-70% cheaper than new valve procurement in India. Most Indian sugar mills and textile mills benefit from our repair path.
What is the typical turnaround time for Hansen valve repair?+
Standard Hansen proportional valve and solenoid repairs are completed in 3-5 working days at Synchronics. Complex manifold cavity lapping and controller board rework may extend to 7-10 days. We offer express 24-48 hour repairs for critical production shutdowns. Door-to-door pickup and delivery across India is included; typical transit time is 2-3 days depending on location.
Can Synchronics repair Hansen EVC electronic controllers if the PCB is damaged?+
Yes. Synchronics has component-level PCB repair expertise for Hansen EVC 100 series and analog ramp controllers. We replace capacitors, amplifier ICs, relay modules, and power supply boards using industrial-rated components. If the PCB is cracked or trace damage is extensive, we source replacement control boards from our OEM network. All repaired controllers undergo function testing at rated voltage and frequency before dispatch.
Do you provide Hansen spare parts and wear kits for preventive maintenance?+
Yes. Synchronics stocks genuine Hansen seal kits, solenoid coils, pressure compensator cartridges, and sub-plate gaskets for proportional valve maintenance in Indian plants. We can supply complete valve overhaul kits matched to your NG10, NG16, or NG25 series. Volume discounts are available for sugar mills and textile factories with multiple proportional valve installations requiring periodic preventive seal replacement.
How do I send my HANSEN 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 HANSEN 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 HANSEN 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 HANSEN 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.
