SCHLOSSER Equipment We Repair — By Category
SCHLOSSER Product Lines We Repair
Our engineers are trained on the full SCHLOSSER product range. Below are the major product families we service.
Schlosser Solenoid Valves - 2/2 and 3/2 Port Series
Direct-acting and pilot-operated solenoid valves for pneumatic and hydraulic applications. Common issues include coil burnout due to voltage surge, spool seizure from contamination, and valve seat erosion in high-flow circuits. Synchronics performs coil rewinding, spool lapping, and pressure testing.
Schlosser Pressure Regulators and Pressure Switches
Precision pressure control and monitoring devices used in compressed air, hydraulic, and gas systems. Typical faults include diaphragm rupture, spring fatigue, pressure drift beyond setpoint, and electrical contact pitting on switches. Synchronics recalibrates and re-seals these units.
Schlosser Flow Control and Check Valve Assemblies
Meter-out and check valve combinations for motion control and load holding in industrial machinery. Wear patterns cause flow drift, and internal contamination can prevent check valve seating. Full disassembly, cleaning, and recalibration restores flow accuracy.
Schlosser Electronic Proportional Valve Drivers and Amplifiers
Compact amplifier cards and driver modules for proportional solenoid control in modern industrial systems. Failure modes include relay burnout, capacitor degradation, and PWM frequency drift affecting valve response. Synchronics stocks replacement components and performs board-level repair.
Schlosser Manual and Pilot-Operated Override Systems
Mechanical override and pilot drain assemblies for emergency operation and system control in complex circuits. Issues arise from stuck manual levers, corroded pilot ports, and loss of pilot pressure signal due to seal degradation. Synchronics rebuilds overrides with OEM seals.
Schlosser Tube Fittings and Quick-Couplers
Precision ported manifold blocks and integrated subplates for Schlosser valve mounting. Leakage at ports and cross-port contamination occur from wear or improper installation. Synchronics re-taps damaged ports, replaces seals, and provides dimensional validation.

Common SCHLOSSER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SCHLOSSER equipment arriving at our workshop.
- ✓Solenoid coil burnout and continuous current draw — In Schlosser 2/2 and 3/2 valve coils, sustained overvoltage from power supply transients or missing protective diodes causes insulation breakdown and open/short circuits. Common in Indian plants where voltage regulation is poor or surge protection is absent.
- ✓Spool stiction and loss of valve response — Schlosser proportional and directional valve spools seize due to mineral contamination in hydraulic oil, salt corrosion in pilot drain lines, or varnish buildup from thermal degradation. This is critical in Indian automotive and machine tool plants with poor filtration.
- ✓Pressure regulator drift and erratic setpoint — In Schlosser PR-10 and PR-20 series, diaphragm thinning, spring relaxation, and seat erosion from cavitation cause pressure to drift beyond ±5% tolerance. High ambient temperature in Indian foundries and metalworking shops accelerates spring fatigue.
- ✓Electrical pilot pressure loss and valve hang-up — In Schlosser pilot-operated proportional valves, coil-to-spool connection failures and blocked pilot ports prevent the spool from moving. Dirt accumulation and salt intrusion in coastal plant environments degrade pilot drain ports, trapping fluid.
- ✓Electronic amplifier relay chatter and intermittent valve actuation — In Schlosser PA-100 and PA-150 proportional drivers, electromagnetic relay contact wear, corroded terminals, and capacitor leakage cause duty-cycle instability and noise-induced false triggers. Poor electrical grounding in Indian industrial panels exacerbates this.
- ✓Manifold block cross-port leakage and pressure loss — Schlosser manifold blocks suffer internal port damage and seal degradation when subplates are over-torqued or when incompatible sealants are applied. Cross-port leakage occurs gradually over months, reducing system efficiency by 15-30% in Indian pump stations.

Frequently Asked Questions — SCHLOSSER Repairs
Do you repair Schlosser equipment anywhere in India?+
Yes. Synchronics repairs the complete Schlosser product range — solenoid valves, pressure regulators, proportional drivers, flow control assemblies, and manifold blocks. We offer PAN India door-to-door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, and all other major cities. All repairs are processed in our certified facility in Vadodara, Gujarat.
What is the typical turnaround time for Schlosser solenoid valve repair?+
Standard Schlosser valve repairs (coil replacement, spool cleaning, pressure calibration) take 7-10 working days. Complex proportional valve rebuilds with manifold block reconditioning may take 12-15 days. Express service (3-5 days) is available for critical production shutdowns; contact our emergency helpline for same-day courier arrangement.
Can Synchronics replace internal seals and springs in Schlosser PR-20 pressure regulators?+
Absolutely. Synchronics stocks OEM-equivalent Fluorocarbon and PTFE seals, calibrated springs, and diaphragm kits for all Schlosser regulator series. We disassemble, clean, and reassemble using verified dimensions, then pressure-test at 1.3x maximum working pressure to confirm accuracy within ±3% of your setpoint. Full documentation and traceability provided.
My Schlosser proportional valve is showing intermittent response — what could be wrong?+
Intermittent response in Schlosser proportional valves typically stems from spool stiction, pilot pressure loss, or electronic driver relay chattering. Synchronics performs multi-point diagnostics: spool resistance mapping, pilot circuit pressure verification, and amplifier signal analysis at your specified frequency. We then deliver a detailed repair plan with cost and timeline, usually involving spool rebuild and seal replacement.
Do you provide test certificates and pressure documentation for repaired Schlosser equipment?+
Yes. Every Schlosser repair returned by Synchronics includes a detailed test certificate documenting pressure range, flow accuracy, electrical resistance, leakage rate, and response time. We perform independent verification on calibrated ISO 17025-aligned test equipment. These certificates are accepted by automotive OEMs, oil majors, and defence contractors operating in India.
How do I send my SCHLOSSER 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 SCHLOSSER 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 SCHLOSSER 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 SCHLOSSER 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.
