SEOQandA_Product

question:Valve not actuating; possible causes and solutions?
answer:Check air pressure (4-7 bar) and power supply (24V DC). Ensure proper voltage and pressure.
question:Excessive air leakage from valve ports?
answer:Inspect seals for wear/damage. Replace seals or entire valve if internal components are degraded.
question:Slow valve response time during operation?
answer:Clean clogged air passages or replace filters. Verify air quality meets ISO 8573-1 standards.
question:Coil overheating or burning out frequently?
answer:Verify voltage matches coil rating (24V DC). Check for short circuits or excessive duty cycles.
question:Valve fails to switch positions after installation?
answer:Confirm correct port connections (A, B, P, R). Test with manual override to isolate electrical/mechanical issues.
