EPA Equipment We Repair — By Category
EPA Product Lines We Repair
Our engineers are trained on the full EPA product range. Below are the major product families we service.
EPA Proportional Directional Control Valves
EPA's flagship proportional spool valves for precise flow direction and pressure control in hydraulic systems. Common issues include spool stiction, solenoid coil burnout, and loss of proportional response due to electronics failure or contamination.
EPA Proportional Pressure Relief Valves
Direct-acting and pilot-operated proportional pressure relief valves for load-holding and system overpressure protection. Typical faults include spring relaxation, pilot poppet wear, and proportional solenoid degradation affecting pressure stability.
EPA Integrated Hydraulic Control Modules
Compact manifold-mounted assemblies combining directional, pressure, and flow control in single units for mobile and stationary machinery. Repair challenges include internal leakage across spools, multi-circuit balancing issues, and control card electronics faults.
EPA Solenoid Coils and Electrical Drivers
Proportional solenoid coils (24 VDC and AC) and integrated driver electronics for EPA valve actuation. Failures include coil winding burnout, sludge accumulation in coil bores, and driver circuit faults causing proportional signal loss.
EPA Flow Control and Meter-Out Valves
Pilot-operated flow control and meter-out valves for smooth motion control in lifting, pressing, and speed-sensitive applications. Common repairs involve poppet stiction, pilot drain blockage, and proportional throttle stuck positions.

Common EPA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EPA equipment arriving at our workshop.
- ✓Solenoid coil burnout or open circuit — EPA proportional solenoid coils fail due to moisture ingress, voltage spikes from unfiltered power supplies, or sustained overcurrent from stuck plungers. Common in humid Indian environments where cooling is poor.
- ✓Spool stiction or slow proportional response — EPA spool surfaces corrode or accumulate hydraulic sludge, increasing friction and preventing smooth proportional actuation. Contaminated fluid and lack of regular filter changes accelerate this wear, especially in Indian textile, cement, and metal-working plants.
- ✓Loss of proportional control or stuck maximum flow — EPA control electronics drift, proportional driver cards fail, or solenoid springs relax causing the spool to stick in one position. Pressure transducer failure can also prevent feedback-based proportional adjustment.
- ✓Internal leakage across spool lands — EPA spool land surfaces wear or develop micro-scratches from contamination and abrasive particles. Pilot pressure imbalances can also widen spool gaps, allowing flow bypass across directional chambers.
- ✓Pilot pressure loss or erratic pilot function — EPA pilot drain lines become plugged with sludge, pilot solenoid clogs, or pilot poppet springs fail. This is common in recycled hydraulic fluid and high-temperature applications prevalent in Indian steel and forging industries.
- ✓No response to proportional command signal — EPA proportional valve electronics lose 4-20 mA signal continuity due to wiring faults, PLC output card failure, or solenoid connector corrosion. Industrial EMI from welding or VFDs can also corrupt proportional signals.

Frequently Asked Questions — EPA Repairs
Do you repair EPA hydraulic equipment anywhere in India?+
Yes. Synchronics repairs the full range of EPA proportional valves, pressure relief valves, solenoid coils, and integrated control modules. We offer door-to-door pickup across India — Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, and all industrial cities. Your EPA equipment is tested, repaired, and recalibrated at our Vadodara facility to factory specifications.
What is the typical turnaround time for EPA proportional valve repair?+
Standard EPA valve repair — solenoid replacement, spool honing, and pressure calibration — takes 3-5 working days once received. Complex jobs involving manifold reconstruction or custom electronics retuning may require 7-10 days. Synchronics provides daily progress updates and ships repaired EPA equipment by courier nationwide.
How do you test EPA proportional valve performance after repair?+
Synchronics uses dedicated proportional valve test benches equipped with pressure gauges, flow meters, and 4-20 mA signal generators. We verify EPA spool response time, proportional linearity across full stroke, pilot pressure balance, and internal leakage limits. All EPA equipment is pressure-tested and logged with full test certificates before return shipment.
Can you repair EPA NG10 sandwich manifolds with multiple proportional sections?+
Yes. Synchronics specializes in multi-section EPA manifolds and modular NG10/NG16 stacks. We disassemble, clean, and individually test each proportional section, replace worn poppets and seals, hone spool bores, and reassemble with proper pilot line sequencing. Complex manifolds are pressure-tested under simulated load conditions and returned ready for immediate installation.
What warranty do you provide on repaired EPA equipment?+
All EPA repairs carry a 12-month workmanship guarantee covering solenoid coils, pressure adjustment drift, and mechanical failures arising from our repair. We also supply spare seals, gaskets, and solenoid boots at cost to help extend equipment life. Contact our service team for warranty claims or spare part ordering.
How do I send my EPA 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 EPA 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 EPA 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 EPA 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.
