HERR-VOSS Product Lines We Repair
Our engineers are trained on the full HERR-VOSS product range. Below are the major product families we service.
Proportional Directional Control Valves
Herr-Voss proportional spool valves with integrated electronics for flow and pressure modulation. Common repairs involve solenoid coil failures, spool stiction, electrical connector corrosion, and onboard controller faults in high-vibration industrial environments.
Pressure and Flow Control Electronics
Standalone pilot-operated pressure relief valves and flow control modules with electronic feedback. Typical failures include pressure transducer drift, solenoid driver IC burnout, and manifold blockage creating false fault signals in closed-loop systems.
Pneumatic Proportional Regulators
Proportional air pressure regulators with integrated control electronics for precision air supply in assembly and packaging lines. Failures stem from diaphragm rupture, electrical noise immunity issues, and spool cartridge wear reducing control accuracy.
Hydraulic System Instrumentation
Pressure transducers, flow sensors, and inline diagnostic monitors for predictive maintenance of hydraulic circuits. Common issues include sensor signal loss, calibration drift, connector water ingress, and amplifier module failure in outdoor plant installations.
Control and Amplifier Modules
Onboard and remote amplifier electronics for proportional valve actuation, PID closed-loop control, and system diagnostics. Repair challenges include PWM power stage failure, noise immunity degradation, and firmware corruption under shock and vibration.

Common HERR-VOSS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HERR-VOSS equipment arriving at our workshop.
- ✓Solenoid coil short circuit on proportional valve — Herr-Voss proportional solenoids in wet or high-vibration environments experience insulation breakdown at coil terminals, often triggered by hydraulic fluid seepage or repeated mechanical shock. Salt-laden humidity in coastal Indian plants accelerates copper oxidation.
- ✓Proportional spool stiction and sluggish response — Herr-Voss proportional directional valves develop internal spool friction when hydraulic fluid degrades or particulate contamination accumulates. Indian plants with poor fluid maintenance schedules often see rapid performance loss within 18-24 months of operation.
- ✓Pressure transducer signal dropout or erratic readings — Herr-Voss pressure transducers fail due to connector oxidation, internal diaphragm rupture, or amplifier IC degradation. High-temperature hydraulic environments (above 70 degC) and repeated pressure pulsations accelerate sensor fatigue in heavy machinery and press applications.
- ✓Control module power supply failure — Herr-Voss amplifier and control modules experience capacitor ripple failures and rectifier diode burnout when subjected to plant-side voltage fluctuations, inadequate power supply filtering, or transient load spikes common in Indian industrial grids with poor PFC infrastructure.
- ✓Loss of proportional valve command signal or jerky actuation — Herr-Voss proportional valve electronics lose signal due to cable shield grounding issues, PWM driver transistor failure, or feedback loop instability from EMI in factories with variable frequency drives (VFDs) and high-power welding equipment commonly found in Indian automotive clusters.
- ✓Solenoid pilot pressure relief valve unresponsiveness — Herr-Voss pilot-operated relief valve solenoids fail when exposed to sustained high ambient temperatures, mineral oil oxidation products, or when the pilot drain line becomes blocked by debris. This is frequent in cement, sugar, and mineral processing plants across India.

Frequently Asked Questions — HERR-VOSS Repairs
Do you repair Herr-Voss equipment anywhere in India?+
Yes. Synchronics repairs the full Herr-Voss product range - proportional directional valves, pressure transducers, pneumatic regulators, and control amplifiers. We offer PAN India door pickup service from Mumbai, Pune, Delhi, Bangalore, Hyderabad, Ahmedabad, Chennai, Kolkata, and all tier-2/tier-3 cities. All equipment is brought to our ISO 9001 certified repair facility in Vadodara, Gujarat for comprehensive diagnosis, repair, and functional testing.
How do you diagnose failures in Herr-Voss proportional valve systems?+
Synchronics uses multi-step diagnostics: visual inspection of solenoid coils and connectors, resistance and insulation megohm testing, bench pressure testing of proportional response, spool response time measurement, and pilot pressure verification. We also perform flow linearity checks and load-step testing to confirm the valve responds correctly across your actual system pressure range. All findings are documented in a detailed test report.
What is the typical turnaround time for Herr-Voss repair?+
Standard non-emergency repairs take 5-7 working days from receipt in Vadodara. Emergency repairs for critical production equipment can be expedited to 48-72 hours if the fault is straightforward (e.g. solenoid replacement, connector repair). Complex faults requiring manifold disassembly or custom calibration may take 10-14 days. We keep Herr-Voss common replacement components in stock to minimise delay.
Can Synchronics repair Herr-Voss equipment that is no longer under warranty?+
Absolutely. Synchronics specialises in out-of-warranty and obsolete Herr-Voss equipment. We repair systems installed since the 1990s. Even if Herr-Voss discontinues a product line, we reverse-engineer function, source or fabricate replacement components, and restore systems to full operational spec. This is especially valuable for Indian plants with aged but critical hydraulic automation assets.
Do you supply replacement Herr-Voss components or only repair?+
Both. Synchronics repairs and rebuilds Herr-Voss equipment. We also supply OEM Herr-Voss replacement components for proportional solenoids, spool cartridges, pressure transducers, and sealed modules. For obsolete parts, we source equivalent industrial-grade alternatives with identical form, fit and function. All supplied components are tested and carry a 12-month warranty.
How do I send my HERR-VOSS 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 HERR-VOSS 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 HERR-VOSS 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 HERR-VOSS 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.
