GRANVILLE-PHILLIPS Equipment We Repair — By Category
GRANVILLE-PHILLIPS Product Lines We Repair
Our engineers are trained on the full GRANVILLE-PHILLIPS product range. Below are the major product families we service.
DV-6M Series Pressure Controllers
Dual-valve pressure regulation units used in semiconductor fab and pharmaceutical equipment. Common failures include solenoid valve stiction, control board capacitor degradation, and feedback sensor drift causing setpoint instability.
KJL Series Ion and Cold Cathode Gauges
Vacuum measurement instruments providing real-time gauge readings for process monitoring. Typical faults include filament burnout, electrode contamination, high voltage supply failure, and display module malfunction.
RGA (Residual Gas Analyzer) Controllers
Mass spectrometry-based systems for gas composition analysis in vacuum chambers. Repair focus areas include electron multiplier tube replacement, RF power supply failure, and quadrupole mass filter alignment drift.
UHV Pressure Transducers
Ultra-high vacuum sensors for aerospace, research labs, and semiconductor processing. Common issues include piezo crystal fracture, output amplifier malfunction, and connector corrosion in harsh chemical environments.
Granville-Phillips Flow Control Modules
Precision mass flow control units integrated into process gas systems. Failures typically involve proportional valve spool stiction, feedback potentiometer wear, and PID loop oscillation requiring controller calibration.

Common GRANVILLE-PHILLIPS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRANVILLE-PHILLIPS equipment arriving at our workshop.
- ✓Pressure controller solenoid valve stiction and drift — Granville-Phillips DV-6M series solenoid valves experience particle contamination and diaphragm degradation in Indian pharmaceutical and food processing environments where ambient humidity and dust are high. Extended idle periods worsen spool stiction.
- ✓KJL series filament burnout and no gauge reading — Granville-Phillips cold cathode and ion gauge filaments fail due to over-voltage from control board regulation drift, or premature burnout in oxygen-rich residual gas atmospheres common in Indian vacuum systems with minor leaks.
- ✓RGA controller high-voltage supply failure — Mass spectrometer high-voltage power supplies in Granville-Phillips RGA modules degrade due to thermal cycling in cleanroom equipment and aging filter capacitors. Indian semiconductor fabs experience wide ambient temperature swings that accelerate component wear.
- ✓UHV transducer zero-offset drift and nonlinear output — Granville-Phillips GP-series transducers experience piezo crystal aging and output amplifier gain drift when exposed to temperature extremes and vibration in Indian industrial process lines. Connector corrosion in humid environments adds measurement noise.
- ✓Flow control proportional valve spool stiction and hunt cycling — Granville-Phillips 277-series proportional valve spools stick due to polymerized residue buildup from reactive process gases (fluorine, chlorine compounds) and moisture ingress. PID loop tuning becomes unstable, causing oscillation around setpoint.
- ✓Control board electrolytic capacitor failure and display malfunction — Granville-Phillips pressure controllers and gauge power supplies use standard electrolytic capacitors rated for industrial temperature ranges. Age, humidity, and continuous power cycling in Indian manufacturing environments cause capacitor ESR rise and ripple voltage increase, degrading display clarity and sensor feedback signal quality.

Frequently Asked Questions — GRANVILLE-PHILLIPS Repairs
Do you repair Granville-Phillips equipment anywhere in India?+
Yes. Synchronics repairs the full Granville-Phillips product range - pressure controllers (DV-6M series), vacuum gauges (KJL series), RGA mass spectrometers, UHV transducers, and flow control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are completed in our Vadodara, Gujarat facility with turnaround typically 5-10 business days.
What is the lead time for Granville-Phillips DV-6M pressure controller repair?+
Most DV-6M controller repairs are completed in 7-10 business days. If solenoid cartridge replacement is required, we maintain stock of OEM-compatible cartridges. Rush repairs can be accommodated within 48-72 hours for critical production outages. We provide free PAN India pickup and return shipping.
Can you calibrate Granville-Phillips KJL ion gauge controllers to customer setpoints?+
Yes. After filament replacement or sensor swap, Synchronics recalibrates all KJL-series controllers to your exact pressure range specifications using certified vacuum standards traceable to NIST. Calibration certificates are provided for all repairs, critical for pharmaceutical and semiconductor compliance audits in Indian facilities.
Do you repair Granville-Phillips RGA (Residual Gas Analyzer) systems with electron multiplier tube failure?+
Yes. We replace Granville-Phillips EM tubes and verify RF signal coupling, quadrupole filter alignment, and data acquisition stability. Complete RGA system validation is performed across the full mass range (typically 1-300 amu) with sensitivity check. Common in Indian semiconductor fabs and research institutes.
What warranty do you offer on Granville-Phillips repairs?+
All Synchronics repairs include 12 months full warranty on parts and labour, covering any defect arising from our repair work. We use OEM Granville-Phillips components where available, and quality-equivalent industrial-grade substitutes for obsolete parts. Warranty is honoured across India with free replacement shipping.
How do I send my GRANVILLE-PHILLIPS 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 GRANVILLE-PHILLIPS 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 GRANVILLE-PHILLIPS 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 GRANVILLE-PHILLIPS 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.
