DEZURIK Product Lines We Repair
Our engineers are trained on the full DEZURIK product range. Below are the major product families we service.
DeZurik Butterfly Valves with Electric Actuators
Heavy-duty butterfly valves with integral electric actuators used in power plants and water treatment. Common issues include actuator motor stalling, position feedback signal loss, and solenoid pilot failure in emergency isolation scenarios.
DeZurik Pneumatic Actuators and Positioners
Fail-safe pneumatic actuators and electro-pneumatic positioners for process control. Repair needs include spring pack degradation, diaphragm rupture, solenoid valve malfunction, and air pilot signal calibration issues.
DeZurik Electronic Control Systems
Integrated control modules for damper regulation, pressure relief, and remote valve actuation. Failures include PCB corrosion in humid industrial environments, relay contact wear, and 4-20mA signal conditioning errors.
DeZurik Solenoid Pilot Systems
Pilot-operated solenoid systems for large-bore valve control in power and water sectors. Common faults: solenoid coil burnout, pilot line blockage, spool stiction, and magnetic core corrosion.
DeZurik Flow Regulation Systems
Integrated flow metering and control units for boiler feedwater, cooling water, and process liquid applications. Issues include orifice plate wear, flow transmitter drift, and regulating valve seat erosion.

Common DEZURIK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DEZURIK equipment arriving at our workshop.
- ✓DeZurik electric actuator motor fails to rotate — Motor winding insulation degradation due to moisture ingress in coastal or high-humidity Indian industrial locations. Thermal overload from valve packing friction or solenoid pilot system blockage also causes motor stall.
- ✓Position feedback signal loss or erratic output — Potentiometer wiper contact wear in the valve position transducer, especially in high-cycle applications common in thermal power plants. Cable corrosion or loose signal connectors also degrade 4-20mA feedback to the PLC.
- ✓Solenoid pilot system fails to energize or drops out — Coil insulation failure due to voltage surges, moisture contamination in solenoid armature cavity, or pilot line pressure instability. Spool stiction from particulate contamination in the pilot oil/air line prevents solenoid response.
- ✓Damper or regulating valve does not maintain set pressure — Diaphragm perforation in pneumatic positioner or regulator, allowing pilot air to escape. Spring pack fatigue, seat erosion from cavitation, or worn spool seals also cause pressure drift over time.
- ✓Electronic control module exhibits intermittent relay chatter or output freeze — PCB relay contact oxidation or solder joint cold-cracking from thermal cycling in outdoor or high-vibration Indian manufacturing environments. Electrolytic capacitor dry-out also causes erratic logic operation and delayed signal response.
- ✓Valve actuator responds sluggishly or sticks at intermediate positions — Internal spring pack corrosion, bearing wear in the output shaft, or adhesion film formation on the valve stem from mineral deposits in process fluid. Inadequate lubrication of pivot joints in high-temperature applications.

Frequently Asked Questions — DEZURIK Repairs
Do you repair DeZurik equipment anywhere in India?+
Yes. Synchronics repairs the complete DeZurik product portfolio — butterfly valves, pneumatic and electric actuators, solenoid pilot systems, and electronic control modules. We offer PAN-India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 cities. All repairs are completed at our 180-engineer facility in Vadodara, Gujarat, with typical turnaround of 5-10 working days.
What is your experience with DeZurik high-cycle butterfly valve actuators in thermal power plants?+
Synchronics has repaired hundreds of DeZurik electric and pneumatic actuators deployed in Indian thermal power plants. We specialize in restoring actuators used in boiler feedwater isolation, air heater damper control, and emergency shutdown applications. Our engineers understand the high-temperature, high-vibration environment and the critical nature of valve response time in power generation. We perform load-testing on restored actuators to verify torque output and speed compliance.
How do you handle DeZurik solenoid pilot failure in emergency isolation scenarios?+
Emergency solenoid pilots must be 100% reliable. Synchronics bench-tests all repaired solenoid coils with rated voltage, continuity, and insulation-resistance megohm testing. We replace coils showing any degradation, clean pilot cartridge spools with non-abrasive media, and verify air flow and pressure drop. Each repaired solenoid is labeled with test data and re-certification, ensuring your emergency isolation systems remain fail-safe.
Can you recalibrate DeZurik position feedback transducers to PLC interface specifications?+
Yes. We recalibrate DeZurik potentiometer feedback transducers using precision current/voltage test equipment to match your PLC 4-20mA input card span and zero. We provide calibration certificates with test data across the full valve stroke. If potentiometer element wear prevents accurate recalibration, we replace with OEM components and re-test to your exact specifications.
What warranty do you offer on repaired DeZurik equipment?+
All Synchronics repairs on DeZurik equipment carry a 12-month parts-and-labour warranty on the repaired component. This covers defects arising from our repair workmanship. We also offer preventive maintenance contracts for critical DeZurik installations in power plants and water utilities, including quarterly inspection, lubrication, and performance verification to extend equipment life.
How do I send my DEZURIK 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 DEZURIK 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 DEZURIK 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 DEZURIK 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.
