PLUMAT Equipment We Repair — By Category
PLUMAT Product Lines We Repair
Our engineers are trained on the full PLUMAT product range. Below are the major product families we service.
NG6 Proportional Directional Spool Valves
Compact 4/3 proportional valves with integrated electronics for small-to-medium flow applications. Common failures include solenoid spool stiction, dither amplifier faults, and feedback potentiometer drift causing erratic actuation and poor load-holding.
NG10 Proportional Pressure Control Valves
Mid-range load-sensing pressure control and directional spool modules for medium-flow industrial hydraulics. Typical faults include pilot spool wear, pressure transducer signal loss, and electronics module saturation under transient loads.
NG16 Heavy-Duty Proportional Valves
Large-flow proportional directional and load-sensing valves for high-pressure plastics and paper machinery. Known issues: solenoid coil burnout from sustained pilot pressure, spool land scoring causing internal leakage, and proportional amplifier module thermal shutdown.
Solenoid Driver and Proportional Amplifier Modules
Integrated electronics for PLUMAT proportional valve control, featuring dither oscillator, feedback compensation, and current limiting. Failures stem from capacitor aging, MOSFET thermal stress, and feedback loop instability causing valve hunting or no-response faults.
Pilot-Operated Load-Sensing Modules
Compact pressure compensators and pilot control sections for NG10/NG16 proportional valve stacks. Common defects: compensator spool stiction, pilot pressure regulator drift, and electronic feedback signal conditioning failures.
Proportional Pressure Relief Cartridges
Direct-acting proportional relief elements for system overpressure protection and load control. Failure modes include seat erosion from cavitation, proportional solenoid coil open-circuit, and spoolway wear reducing setting accuracy.

Common PLUMAT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in PLUMAT equipment arriving at our workshop.
- ✓Solenoid coil burnout on proportional pilot solenoids — PLUMAT NG10 and NG16 proportional pilot solenoids fail when continuous pilot pressure or sustained current exceeds design margin. In Indian high-ambient (40-45°C) facilities, inadequate cooling of pilot cavity exacerbates coil insulation breakdown. Mineral oil contamination accelerates winding failure.
- ✓Spool stiction and erratic valve response — PLUMAT NG6 and NG10 proportional spools stick due to microscopic corrosion ridges, salt-air deposits (common in Indian coastal plants), or mineral varnish buildup from oil degradation. Dither frequency loss or proportional amplifier module noise rejection failure amplifies the stiction effect.
- ✓Proportional amplifier module thermal shutdown and oscillation — PLUMAT driver electronics (24VDC and 48VDC versions) suffer from aged electrolytic capacitor leakage, MOSFET gate-drive circuit failure, and feedback network saturation. In Indian summer (45°C+), inadequate heatsinking causes ripple current foldback and intermittent proportional command loss.
- ✓Pressure transducer signal loss and erratic pressure feedback — PLUMAT NG10 and NG16 load-sensing pressure transducers (0-250bar, 0-350bar) develop intermittent output due to connector corrosion, internal sensor element fatigue, or electronics interface module failure. Indian high-vibration textile and plastic machinery exacerbate mechanical stress on transducer housing.
- ✓Load-sensing compensator spool wear and internal leakage — PLUMAT NG16 load-sensing compensator spools wear prematurely in high-cycle applications (Indian textile dyeing machines, plastic injection molding). Cavitation erosion and particle impingement enlarge spool spoolways, causing system pressure loss, poor flow modulation, and reduced load-holding capability.
- ✓Solenoid coil open-circuit and proportion valve lock-up — PLUMAT proportional directional valve solenoids fail open-circuit due to vibration-induced wire breakage at coil terminations, thermal cycling fatigue (especially in Indian monsoon regions with humidity swings), or manufacturing defect in winding termination potting.

Frequently Asked Questions — PLUMAT Repairs
Do you repair PLUMAT equipment anywhere in India?+
Yes. Synchronics specialises in PLUMAT proportional valve repair, solenoid driver modules, and load-sensing electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other major industrial cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat. Typical turnaround for PLUMAT proportional valves is 10-15 working days including testing and calibration.
What is the warranty on PLUMAT valve repairs?+
Synchronics provides 12 months (365 days) comprehensive warranty on all PLUMAT proportional valve repairs and solenoid driver module replacements, covering parts and labour. Warranty covers manufacturing defects, solenoid rewind failures, and proportional amplifier electronics faults. Wear-related issues (spool land scoring, seat erosion) are covered if caused by contamination or design overstress rather than plant maintenance neglect. Extended warranty (24 months) is available for critical production equipment.
Can you repair PLUMAT NG10 and NG16 load-sensing pilot modules separately from main valve stacks?+
Yes. Synchronics repairs PLUMAT pilot-operated load-sensing modules (NG10 and NG16) as standalone components. Compensator spool assemblies, pressure regulators, and solenoid pilot elements are routinely replaced and calibrated. We stock common pilot module spares and offer express repair (5-7 days) for emergency breakdowns. Pilot setting is verified using certified pressure test equipment (0-350 bar range) before shipment back to your facility.
How do I know if my PLUMAT proportional valve has dither amplifier failure?+
PLUMAT proportional valve dither amplifier failures exhibit as spool stiction, sluggish valve response, or intermittent actuation. You may observe low audible 'buzzing' (dither oscillation) loss, or proportional command input producing no proportional spool movement (valve locks in neutral). Synchronics diagnoses this by testing the proportional amplifier module on the bench with 4-20 mA command signals and measuring solenoid current ripple. Replacement modules and full system re-tuning restore smooth proportional response within 2-3 days.
Do you offer on-site troubleshooting and preventive maintenance for PLUMAT proportional valve systems?+
Yes. Synchronics' field engineering team offers on-site diagnostics, fluid sampling, proportional valve performance testing, and preventive maintenance scheduling for PLUMAT installations across India. We perform oil cleanliness audits (ISO 4406 particle counting), solenoid coil resistance trending, and load-sensing pressure transducer calibration verification. Annual predictive maintenance contracts are available for high-uptime critical machinery like textile dyeing lines and plastic extrusion presses.
How do I send my PLUMAT 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 PLUMAT 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 PLUMAT 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 PLUMAT 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.
