Frequently Asked Questions
Common questions from overseas importers, distributors and OEM buyers
Q1: How do you guarantee air/fluid tightness and flow accuracy on your solenoid valves? Do you perform 100% end-of-line testing?
A: Yes, every single valve undergoes 100% automated end-of-line testing before packaging. We run differential pressure leak tests (ensuring internal leakage is below 1.0 cc/min) and dynamic airflow/flow-rate tests against standard OEM performance curves. We never use random sampling for critical sealing components.
Q2: What materials do you use for the internal seals and electromagnetic coils? Engine bays in our market reach extreme temperatures.
A: We use FKM (Viton) or high-grade NBR for all internal seals, which offers superior resistance to ethanol-blended fuel, oil, and extreme heat up to 150°C. For the electromagnetic coils, we use Class H/180°C copper wire with automated encapsulation to prevent thermal short-circuiting and vibration failure.
Q3: What is your actual defect rate, and how do you handle claim warranty if a customer returns a faulty valve?
A: Our historical defect rate is strictly controlled below 0.3%. We provide a 12-Month / 30,000 KM warranty. In the rare event of a verified manufacturing defect, we operate a 1:1 free replacement or instant credit policy on your next order. We do not require you to ship low-value defective units back to China, saving your logistics and handling expenses.
Q4: Do you provide a full OE cross-reference list, and are your part numbers aligned with TecDoc or major aftermarket brands?
A: Absolutely. We maintain a database covering OE cross-references for major US, European, and Asian vehicles, as well as cross-references to major aftermarket brands (like Dorman, Standard Motor Products, Pierburg, and Bosch). We can send you a complete Excel matrix to match your local catalog instantly.
Q5: Can you laser-engrave our own part number/logo on the valve body and supply customized brand packaging?
A: Yes, we offer full OEM/Private Labeling services. We can laser-engrave your logo, custom OE number, and batch production code on the solenoid plastic/metal housing for traceability. We also provide customized color boxes, barcode labels, and master carton packaging with low MOQ thresholds.
