FARVAL Product Lines We Repair
Our engineers are trained on the full FARVAL product range. Below are the major product families we service.
FARVAL Proportional Directional Control Valves
FARVAL's flagship modular proportional directional spool valves with integrated electronics control. Common issues include spool stiction, magnetic coil burnout, pressure compensator drift, and electronic signal loss causing erratic machine motion or system lockup.
FARVAL Proportional Pressure Relief Valves
Precision pilot-operated proportional relief valves used in high-pressure hydraulic circuits (280-350 bar). Typical failures include pilot poppet erosion, main spool wear, solenoid coil degradation, and feedback transducer malfunction leading to pressure creep or sudden unloading.
FARVAL Electronic Control Modules and Amplifiers
Integrated proportional valve amplifiers and onboard electronics for FARVAL valves. Failures stem from moisture ingress, capacitor degradation, mosfet burnout, and connector corrosion in humid Indian mill environments, resulting in no response to command signals.
FARVAL Hydraulic Manifold Blocks and Sandwich Valves
Custom and standard manifold assemblies combining proportional spools, relief, and logic elements. Repair challenges include internal port leakage, cavity surface scoring, cartridge seal degradation, and cavity thread damage from over-torque or corrosion.
FARVAL Proportional Flow Control Valves
Variable orifice proportional throttle and pressure compensated flow dividers used in servo and proportional motion control. Common faults include compensator piston stiction, metering edge wear, spool valve blockage, and electronic feedback sensor failure.

Common FARVAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FARVAL equipment arriving at our workshop.
- ✓Proportional spool stiction and sluggish response — FARVAL proportional directional valve spools experience stiction due to varnish buildup from degraded hydraulic fluid, microcontamination (>18 micron ISO cleanliness), or corrosion of the spool bore. High ambient temperatures in Indian textile mills and foundries accelerate fluid breakdown, creating sticky residue on precision spool surfaces.
- ✓Proportional solenoid coil burnout and no valve response — FARVAL proportional solenoids are vulnerable to thermal overload when supply voltage spikes exceed 28VDC, during long uninterrupted energization without cooling, or when control amplifiers malfunction and deliver continuous current. Humidity in coastal Indian plants and salt spray near ports also degrade magnet wire insulation.
- ✓Pressure compensator spool drift and creeping discharge pressure — FARVAL proportional pressure relief compensators drift due to internal leakage around main poppet (from erosion or contamination), wear of the pilot poppet, or spring relaxation. Dirty oil (>19 ISO) introduces particles into tight compensator clearances, causing slow drift of 10-40 bar over hours of operation.
- ✓Electronic amplifier failure — no proportional command signal output — FARVAL ECOM and ECAM amplifier modules fail due to capacitor dry-out (especially in 45-50°C Indian workshop environments), mosfet gate oxide breakdown from voltage spikes, or connector pin corrosion from moisture and salt air. Input/output stages short internally, blocking proportional signal transmission.
- ✓Manifold internal leakage between A-B ports and T return — FARVAL sandwich and subplate manifolds develop internal port leakage when spool sleeves corrode (especially in packaging and chemical industries where moisture and vapors are present), seal rings degrade from fluid breakdown or thermal cycling, or cartridge seats are damaged by contamination or installation torque errors.
- ✓FARVAL pressure transducer signal dropout or erratic readings — Integrated pressure transducers in FARVAL proportional valve blocks fail when electrical connectors experience moisture ingress, transducer diaphragms rupture from shock pulses or water hammer, or electronic signal conditioning circuits corrode. Common in high-vibration machinery and humid environments typical of Indian spinning mills and plastic processing units.

Frequently Asked Questions — FARVAL Repairs
Do you repair FARVAL equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete FARVAL product portfolio — proportional directional valves, pressure relief systems, flow controls, electronic amplifiers, and integrated manifold blocks. We offer pan-India door pickup and delivery from major cities: Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Kolkata, Ahmedabad, and 50+ smaller industrial hubs. All repairs are performed at our Vadodara facility and typically completed in 7-12 working days for standard hydraulic remanufacture.
What is your turnaround time for FARVAL proportional valve repair?+
Standard FARVAL proportional directional valve repair (spool honing, seal replacement, solenoid testing, manifold pressure testing) takes 5-7 working days. Emergency repairs with priority queuing available in 2-3 days. Proportional relief cartridge repair is 3-5 days. Electronic amplifier repair (component-level diagnostics, soldering, calibration) is 4-6 days. All timelines exclude PAN India pickup and delivery, which adds 2-4 days depending on location.
How do you prevent FARVAL spool stiction in Indian humidity and high-temperature environments?+
Synchronics uses multi-stage protection: (1) We hone FARVAL proportional spools to ISO Ra 0.4 micron finish, reducing surface area for varnish adhesion. (2) We recommend ISO 16/14/11 hydraulic fluid with strong anti-varnish and anti-oxidation additives suitable for 45-50°C ambient Indian plants. (3) We install high-efficiency 3-micron return filters and condition offline loops for new installations. (4) We apply light-duty anticorrosion coatings to bare metal spool surfaces. These measures extend spool life 3-5 years in challenging Indian industrial climates.
Can Synchronics repair FARVAL manifold cavities that are stripped or damaged?+
Yes. When FARVAL sandwich valve cavities are over-torqued, corroded, or thread-stripped, Synchronics can remanufacture manifold blocks. We use precision boring and thread-insert technology to restore cavity geometry and add helicoil inserts for cartridge seats. We then pressure-test the repaired manifold to 1.5x rated system pressure. Cost is typically 40-60% of replacement manifold pricing, making manifold repair economically attractive for Indian textile mills and OEMs with tight capital budgets.
Does Synchronics supply replacement FARVAL proportional solenoids and spare coils?+
Yes. We stock genuine FARVAL proportional solenoid coils and replacement assembly units for common models (CETOP 03, CETOP 05, NG10, NG16 series). We also wind custom FARVAL solenoids if long lead times are impacting your production. All solenoid replacements include insulation testing (5 Megohm minimum), functional testing at rated voltage, and 6-month warranty. For emergency situations in Indian plants, we offer same-day dispatch from our Vadodara warehouse.
How do I send my FARVAL 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 FARVAL 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 FARVAL 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 FARVAL 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.
