DIXIE UNION Product Lines We Repair
Our engineers are trained on the full DIXIE UNION product range. Below are the major product families we service.
Valve Positioners
Pneumatic and electro-pneumatic positioners for control valve automation. Common faults include air leak detection sensitivity failures, feedback transducer drift, and solenoid spool stiction causing hunting or sluggish response.
Solenoid Actuators
Direct-acting and pilot-operated solenoid valve assemblies for on-off flow control. Typical issues include coil burnout, plunger seizure, and armature erosion leading to intermittent actuation.
Electronic Controller Modules
Microprocessor-based control units for integrated valve sequencing and pressure regulation. Common failures include analog input card degradation, relay chatter, and firmware corruption.
Pressure Reducing Regulators
Balanced and unbalanced poppet regulators for upstream and downstream pressure control. Repair focuses on seat erosion, spring fatigue, and compensator diaphragm replacement.
Transducers and Sensors
Pressure, level, and flow transmitters with analog and digital outputs. Issues include diaphragm rupture, electronics module corrosion, and signal output instability.
Pilot Supply Modules
Standalone pilot gas generation and conditioning equipment for remote valve operation. Common problems include pilot regulator lock-up, filter bowl cracking, and isolation check valve leakage.

Common DIXIE UNION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIXIE UNION equipment arriving at our workshop.
- ✓Valve positioner drift and unstable process control output — Feedback transducer signal degradation, dirty air supply, or internal feedback linkage wear in Dixie-Union positioners causes proportional control response to weaken. Trapped moisture and corrosion accelerate failure in humid Indian industrial environments.
- ✓Solenoid coil burnout and no actuation response — Sustained over-voltage, thermal stress from inadequate cooling, or water ingress into the coil assembly causes insulation breakdown in Dixie-Union solenoid valves. Corrosive plant atmosphere accelerates winding failure.
- ✓Pilot supply regulator lock-up and no downstream flow control — Particulate contamination, valve seat erosion, and spring fatigue in Dixie-Union pilot regulators restrict pressure adjustment range. Moisture condensation can freeze the adjustment stem.
- ✓Electronic controller module intermittent relay switching and erratic valve sequencing — Relay contact arcing, analog input card edge connector corrosion, and board-level capacitor failure in Dixie-Union ECM units cause control logic failure. PCB moisture absorption reduces insulation resistance over time.
- ✓Pressure transmitter zero drift and incorrect plant instrumentation readings — Diaphragm fatigue, reference pressure port blockage, and electronics module thermal drift in Dixie-Union transducers cause output signal instability. Plant vibration accelerates sensor failure.
- ✓Check valve leakage and downstream pilot pressure loss in pilot supply modules — Poppet and seat erosion, spring weakening, and particle impaction in Dixie-Union pilot check valves allow reverse flow when pressure upstream drops. Saltwater or chemical mist corrosion weakens seat sealing.

Frequently Asked Questions — DIXIE UNION Repairs
Do you repair Dixie-Union equipment anywhere in India?+
Yes. Synchronics repairs the full Dixie-Union product range — valve positioners, solenoid actuators, electronic controllers, pressure regulators, transducers, and pilot supply modules. We offer PAN India door pickup and courier service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all other industrial cities. Equipment is serviced in our 25,000+ sq ft facility in Vadodara, Gujarat, with TAT of 7-14 days for most repairs.
What is the typical turnaround time for Dixie-Union valve positioner repair?+
Standard positioner repair including solenoid replacement, transducer calibration, and full functional testing typically requires 5-7 working days. For critical installations, Synchronics offers expedited 48-hour turnaround for essential calibration and electronics module repairs. We maintain stock of common Dixie-Union spare components and rebuild assemblies to minimize downtime.
Can Synchronics recalibrate Dixie-Union pressure transmitters to our plant's exact specifications?+
Absolutely. Our calibration lab is equipped with certified pressure standards traceable to international metrology institutes. We recalibrate Dixie-Union PT-1000, LT-2000, FT-3000, and MT-4000 series transmitters to your exact zero, span, and linearity requirements. Certificate of calibration with uncertainty data is provided with every repair, and equipment is tested across your full operating pressure range.
How do I know if my Dixie-Union positioner solenoid is failed or just clogged?+
Synchronics diagnoses solenoid condition through coil insulation testing, resistance measurement, and bench actuation testing under controlled air supply. If the solenoid fails to lift the armature at rated voltage with clean pilot air, we replace it with a genuine Dixie-Union coil assembly. Often, sluggish response is caused by valve port blockage rather than solenoid failure — our engineers identify the root cause before recommending replacement.
Do you stock genuine Dixie-Union spare parts and rebuild kits?+
Yes. Synchronics maintains inventory of common Dixie-Union solenoid coils, positioner feedback transducers, regulator cartridges, check valve kits, diaphragm seals, and spring assemblies. For hard-to-source components, we work with authorized Dixie-Union distributors across India to procure parts within 48-72 hours. All spares are genuine OEM and come with warranty coverage on repairs.
How do I send my DIXIE UNION 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 DIXIE UNION 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 DIXIE UNION 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 DIXIE UNION 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.
