ABB KENT-TAYLOR Product Lines We Repair
Our engineers are trained on the full ABB KENT-TAYLOR product range. Below are the major product families we service.
KENT-TAYLOR Type 55 Positioners
Pneumatic electro-pneumatic positioners for sliding-stem and rotary valve control. Common faults include diaphragm tears, solenoid coil failure, and feedback mechanism wear affecting process stability.
KENT-TAYLOR Type 145 Digital Valve Controllers
Modern microprocessor-based valve controllers with fieldbus integration (HART, Profibus). Failures include PCB corrosion, pressure transducer drift, and valve stiction compensation circuit malfunction.
KENT-TAYLOR Flow Control Regulators
Pressure and flow regulating devices for process fluids in refining and chemical plants. Typical issues: pilot valve blockage, spring fatigue, and control spool stiction from process fluid contamination.
KENT-TAYLOR Electronic Actuators
Linear and rotary actuators with integrated electronics for valve automation. Common failures include stepper motor burnout, limit switch corrosion, and encoder signal loss in humid coastal refineries.
KENT-TAYLOR Pressure Transmitters
4-20mA and smart transmitters for process monitoring and control feedback. Repair issues: silicon diaphragm cracks, amplifier board failures, and zero/span drift in temperature-cycling applications.

Common ABB KENT-TAYLOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ABB KENT-TAYLOR equipment arriving at our workshop.
- ✓Type 55 Positioner Diaphragm Rupture — KENT-TAYLOR Type 55 positioner diaphragms (typically neoprene or EPDM) fail from cyclic pressure loading, chemical exposure from process leaks, or manufacturing defects. Rupture causes loss of control response and erratic valve hunting.
- ✓Type 145 Controller PCB Corrosion and Signal Loss — ABB KENT-TAYLOR Type 145 digital controllers installed in humid refinery environments or near cooling towers suffer PCB moisture ingress and corrosion of HART modem circuits, pressure transducer amplifiers, and solenoid driver transistors.
- ✓Electro-Pneumatic Solenoid Coil Open Circuit — KENT-TAYLOR solenoid coils in Type 55 and older positioners open due to insulation breakdown from heat cycling (common in furnace control lines), moisture ingress in humid coastal plants, or manufacturing wire fracture at the spool connection.
- ✓Flow Regulator Control Spool Stiction — KENT-TAYLOR Type 90/91/92 regulators used in crude oil and heavy process fluid applications develop spool stiction when contaminants (scale, corrosion particles, polymer deposits) coat the precision spool bore, preventing smooth valve response.
- ✓Pressure Transmitter Zero Offset and Non-Linearity — ABB KENT-TAYLOR PT-4 transmitters experience permanent zero offset when the silicon diaphragm develops micro-cracks from freeze-thaw cycles (common in northern India refineries) or loses calibration from amplifier IC aging and component drift.
- ✓Digital Valve Controller HART Modem Failure — Type 145 controllers fail to communicate with HART handheld communicators or DCS systems when the HART modem IC (typically AD7688 or equivalent integrator circuit) develops parametric failures, or protective zener diodes fail under electrostatic discharge or lightning surge.

Frequently Asked Questions — ABB KENT-TAYLOR Repairs
Do you repair ABB KENT-TAYLOR equipment anywhere in India?+
Yes. Synchronics repairs all ABB KENT-TAYLOR product families — positioners, digital valve controllers, regulators, actuators, and transmitters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All repairs are handled at our main facility in Vadodara, Gujarat, with typical turnaround of 7-10 working days.
What is your experience repairing KENT-TAYLOR Type 145 DVC controllers in the oil and gas sector?+
Synchronics has repaired 200+ Type 145 controllers used in Indian refineries and upstream facilities. We specialize in HART modem restoration, pressure transducer recalibration, solenoid driver circuit replacement, and Profibus gateway troubleshooting. We also reconfigure valve characterization tables post-repair and perform live DCS integration testing before returning equipment to your plant.
Can you recalibrate KENT-TAYLOR pressure transmitters to my process specification?+
Absolutely. Synchronics recalibrates all KENT-TAYLOR PT-4 and PT-4-DI transmitters to your exact 4-20mA range (e.g. 0-350 bar, 0-25 kg/cm2). We use NIST-traceable pressure calibrators accurate to 0.1 percent and provide post-repair calibration certificates with your equipment.
What is the typical lifespan of a KENT-TAYLOR Type 55 positioner diaphragm, and when should I plan replacement?+
KENT-TAYLOR Type 55 diaphragms typically last 5-10 years depending on process fluid chemistry, pressure cycling frequency, and ambient humidity. Neoprene diaphragms are more prone to ozone cracking in open-air installations. Synchronics recommends preventive diaphragm replacement every 7-8 years in refinery applications. We stock OEM diaphragms and can exchange positioners with minimal downtime.
Do you offer on-site emergency repair for KENT-TAYLOR equipment at my plant?+
Yes. Synchronics offers rapid field support for critical process valve failures. Our service team can travel to major Indian industrial hubs (Mumbai, Vadodara, Ahmedabad, Pune, Delhi) for on-site diagnostics, component swap-out, and commissioning. Contact our emergency support line for same-day coordination.
How do I send my ABB KENT-TAYLOR 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 ABB KENT-TAYLOR 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 ABB KENT-TAYLOR 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 ABB KENT-TAYLOR 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.
