FUJIKIN Equipment We Repair — By Category
FUJIKIN Product Lines We Repair
Our engineers are trained on the full FUJIKIN product range. Below are the major product families we service.
Pressure Reducing Regulators (PRV/PRD Series)
FUJIKIN's core pressure regulation technology for gas and liquid applications. Common issues include seat wear causing creep, diaphragm fatigue, vent blockages, and loss of setpoint accuracy. Precision valve rebuilds and recalibration are essential.
Mass Flow Controllers (MFC Series)
Electronic mass flow control for semiconductor and chemical processing. Repair typically involves sensor drift correction, thermal compensation circuit failures, solenoid drive electronics, and flow measurement recalibration to ensure wafer-fab specification compliance.
Micro-Flow Pressure Switches (NSV/PSB Series)
Low-range pressure switches for critical process monitoring and safety interlocks. Failures include micro-switch contact oxidation, diaphragm micro-ruptures, and calibration drift at set points below 2 bar, common in cryogenic and ultra-pure gas applications.
Back Pressure Regulators (BPV Series)
Counter-pressure control for liquid and gas return lines in closed-loop systems. Typical faults: pilot stage orifice blockages, dome pressure failure, and incorrect spring rate causing system instability or overflow.
Precision Flow Meters (RK Series)
Variable area and electronic flow measurement for process verification and feed control. Failures include float jamming, turbine rotor bearing wear, and calibration loss due to fluid contamination or corrosion in aggressive chemical media.
Vacuum and Cryogenic Regulators (VRG/CRV Series)
Specialized regulators for LNG, cryogenic nitrogen, and ultra-high vacuum applications. Unique failure modes include ice blockage at valve seats, valve stiction at cryogenic temperatures, and diaphragm embrittlement requiring specialized materials expertise.

Common FUJIKIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FUJIKIN equipment arriving at our workshop.
- ✓Pressure regulator creep and setpoint drift — FUJIKIN diaphragm and seat wear allows internal leakage, causing outlet pressure to rise uncontrolled when inlet pressure increases. Common in continuous-duty applications running 8000+ hours without maintenance, especially with corrosive or high-temperature gases.
- ✓Mass flow controller sensor drift and non-linearity — FUJIKIN MFC thermal compensation circuits degrade due to sensor aging, PCB corrosion from moisture ingress, or calibration loss caused by fluid contamination bridging the sensor element. Drift typically manifests as 5-15% flow error across operating range.
- ✓Back pressure regulator pilot stage blockage and instability — FUJIKIN BPV pilot orifices clog with particulate, corrosion products, or precipitated liquids when process fluids exceed contamination limits or pH tolerance. System pressure oscillates or spikes uncontrollably, damaging downstream equipment.
- ✓Cryogenic regulator valve stiction and freeze-up — FUJIKIN CRV and VRG regulators designed for LNG service experience valve stiction when ambient temperature drops, thermal cycling induces lubricant thickening, or trace moisture freezes in the valve cavity. Outlet pressure becomes unresponsive to inlet changes.
- ✓Pressure switch contact oxidation and false trip — FUJIKIN NSV and PSB micro-switch contacts oxidize or arc when switching low-current DC signals (under 100 mA), common in semiconductor and pharma process automation. Switch closes at 2.5 bar but won't re-open until pressure drops to 0.8 bar — creating dangerous process hangs.
- ✓Flow meter rotor bearing wear and output signal loss — FUJIKIN RK series turbine meters wear bearing seats under sustained 500+ Hz operation in high-flow applications. Rotor wobble increases drag, reduces pulse frequency, and causes flow under-reading or intermittent signal dropout to the flow computer or DCS.
