SUPVAN Equipment We Repair — By Category
SUPVAN Product Lines We Repair
Our engineers are trained on the full SUPVAN product range. Below are the major product families we service.
SUPVAN Solenoid Directional Control Valves
3/2 and 4/3 solenoid-operated spool valves with NG6 (CETOP-05) cavity mounting. Common failures include coil winding shorts, spool seizure from contaminated air, and pilot drain port blockages in high-temperature textile applications.
SUPVAN Pressure Reducing and Pilot-Operated Valves
Direct and pilot-operated pressure reducing cartridges (cavity NG10, NG16) with integral or remote pressure compensators. Repair focus: spring hysteresis, pilot line erosion, and spool stiction under contaminated media.
SUPVAN Flow Control and Check Valve Cartridges
Modular flow control inserts and pilot-to-open check cartridges for manifold systems. Typical failures: orifice erosion, spring relaxation, and pilot ratio drift in high-cycle packaging machinery.
SUPVAN Integrated Manifold Blocks and Valve Islands
Custom-ported ductile iron manifolds with cavity-mounted SUPVAN logic and proportional valves. Common issues: internal port leakage, cavity thread stripping, and cross-port contamination in multi-circuit systems.
SUPVAN Proportional and Solenoid Coil Assemblies
Replacement solenoid coils (24 VDC, 110 VAC, 220 VAC) with integrated connectors for SUPVAN valve family. Frequent repair: coil rewinding, connector corrosion repair, and voltage rating conversion for Indian industrial sites.
SUPVAN Proportional Directional Valves
NG10 and NG16 proportional spool valves with integrated electronics and onboard amplifiers. Repair complexity: spool linearity issues, electronics module failure, and solenoid force imbalance in servo applications.

Common SUPVAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SUPVAN equipment arriving at our workshop.
- ✓Solenoid coil burnout and intermittent valve actuation — SUPVAN solenoid coils fail due to prolonged power supply voltage spikes (common on Indian industrial sites with unstable grid), moisture ingress in humid climates, or thermal stress in foundries and heat-treating plants. Intermittency indicates partial winding failure or corroded coil connector pins.
- ✓Directional spool stiction and slow valve response — SUPVAN valve spools stick due to accumulated airborne contamination (metallic fines from machine tool wear, textile dust, casting sand residue) coating the spool bore. Lack of air filtration below 10 micron exacerbates the problem in Indian manufacturing clusters.
- ✓Pilot-operated valve creep and pressure regulation drift — Spring hysteresis and pilot ratio degradation in SUPVAN pressure reducing cartridges occurs after prolonged cycle testing or exposure to pulsating loads. Pilot line erosion from cavitation also shifts the pressure setpoint unpredictably.
- ✓Manifold block port leakage and cross-port contamination — SUPVAN manifold blocks develop internal leakage when cavity-mounted valve seals wear or when cavity threads strip due to assembly torque errors. Cross-port contamination occurs when low-pressure return passages erode and communicate with high-pressure sections.
- ✓Proportional valve electronics module and amplifier failure — SUPVAN proportional valve onboard amplifiers and controller modules fail from moisture contamination, transient voltage surges from motor switching, or inadequate EMI shielding in plants with arc welders or induction furnaces nearby.
- ✓Solenoid valve connector corrosion and water ingress — SUPVAN valve connectors corrode in humid manufacturing environments (especially textile and paper plants) where steam and moisture persist. Condensation inside connector shells causes pin oxidation and intermittent electrical contact.

Frequently Asked Questions — SUPVAN Repairs
Do you repair SUPVAN equipment anywhere in India?+
Yes. Synchronics repairs the full SUPVAN pneumatic and electro-pneumatic product range — solenoid directional control valves, pressure reducing cartridges, proportional valve assemblies, manifold blocks, and replacement coils. We offer PAN India pickup and delivery from Vadodara, Gujarat. Express service available for critical equipment affecting production in Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, and Ahmedabad.
How do I know if my SUPVAN valve has failed or just needs cleaning?+
SUPVAN valve performance can degrade gradually. If your valve is slow to respond (>200ms response time), leaking internally across the spool, or unable to hold setpoint pressure, it likely needs service. Synchronics performs free diagnostic testing — we clean minor contamination, then bench test response and leakage rates. If the valve fails functional tests, we provide a repair quote or discuss replacement options.
What is the typical repair turnaround for a SUPVAN solenoid directional control valve?+
Standard turnaround is 3-5 working days for solenoid coil replacement or spool cleaning and seal renewal. Express 24-48 hour service available for NG6 cavity valves on critical production lines — we keep common SUPVAN spare parts and solenoid coils in stock. Complex proportional valve repairs involving electronics or manifold port rework may take 7-10 days.
Can Synchronics rewind SUPVAN solenoid coils and match exact voltage ratings?+
Yes. Synchronics has SUPVAN solenoid coil winding capability in-house. We rewind 24 VDC, 110 VAC, and 220 VAC coils to original specifications, test insulation and pull force, and install sealed IP67 connectors. We also handle voltage conversions if your plant has switched to different supply (e.g., converting a 110 VAC coil to 220 VAC). Custom coil orders take 5-7 days.
Do you supply replacement SUPVAN manifold blocks if repair is not economical?+
We assess manifold repair costs versus replacement every time. If internal port leakage requires extensive rework or cavity thread repair, we provide quotes for genuine SUPVAN replacement blocks. We also have relationships with SUPVAN distributors across India for procurement of OEM spare parts. Lead time for OEM blocks is typically 2-3 weeks; refurbished SUPVAN manifolds from our inventory are available in 3-5 days.
How do I send my SUPVAN 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 SUPVAN 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 SUPVAN 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 SUPVAN 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.
