One Partner for Your System's Entire Lifecycle
From preventive care to modernization — AVVS keeps critical air systems alive, compliant and efficient. Worldwide.
Service 01
Stop Failures Before They Start
Comprehensive scheduled inspections of all air valve components — valves, actuators, sensors, controllers, transformers and linkages. We document everything for compliance, flag wear before it fails, and keep your facility audit-ready all year.
- Annual inspection protocols
- Wear & damage detection
- Full documentation for compliance
Service 02
Fast Diagnosis. Permanent Fixes.
From mechanical jams and spring damage to electrical failures, network faults and software issues — our specialists diagnose the root cause and repair it properly, not just patch the symptom.
- Mechanical: jams, spring damage, misalignment, worn parts
- Electrical: transformers, actuators, controllers, wiring, network loops
- Software: recalibration, reprogramming, controller recovery
Service 03
Accuracy You Can Measure. Literally.
We calibrate sidewall sensors, sash position sensors and feedback loops to laboratory-grade accuracy, set correct alarm thresholds, and tune PID parameters so your system responds exactly as it should.
- ±0.5% full-scale measurement accuracy
- Alarm threshold & PID tuning
- Recalibration after every maintenance or upgrade

Frequently Asked Questions
Service & Maintenance Answers
What does preventive maintenance for air valves include?
A full lifecycle check: venturi valve calibration and stroke testing, controller firmware and setpoint verification, pressure differential testing, alarm checks, and a documented report with recommendations — so failures are caught before they happen.
How fast is your emergency response?
We respond within 24 hours, and 24/7 rapid response is available for isolation rooms and critical environments where downtime is not an option. Remote diagnostics can begin immediately.
Are your technicians Triatek certified?
Yes. Every AVVS technician is trained and certified on Triatek systems — venturi valves, FMS-1650 controllers and hospital monitoring platforms — giving you factory-grade expertise on site.
Can you modernize an older Triatek system?
Absolutely. We upgrade legacy controllers, replace worn venturi valves, refresh monitoring dashboards and bring aging systems up to current standards — without replacing what still works.
Do you provide calibration certificates?
Yes. Every calibration and verification is documented with a certificate and report, traceable to the instruments and standards used — ready for audits and compliance reviews.
