Product Advantages & Benefits
- Heavy-Duty Construction: PP-T30 material offers superior impact resistance and long-term durability in harsh environments, including high humidity and UV exposure common in Southeast Asia.
- Robotic Arm Mass Production: Our fully automated injection molding lines, integrated with robotic arms, ensure consistent quality, reduced cycle times, and cost-effective large-volume orders for OEMs.
- Pressure Equalization Performance: The valve quickly releases internal pressure buildup inside NEV battery packs, preventing deformation or rupture while maintaining a sealed environment against dust and water ingress (IP67 equivalent).
- Customizable Design: We offer flexible thread sizes, colors, and even integrated mounting brackets. Lead times for custom molds are typically 2–4 weeks.
- TS16969 Certified Quality: Our production processes are audited to meet rigorous automotive industry standards, ensuring traceability and defect-free parts.
- Cost-Effective for SE Asia OEMs: With our factory located in Changzhou, Jiangsu, we provide competitive pricing and fast shipping via Jiangsu, Shanghai, or Shenzhen ports. Direct container loading is available.
In addition to the standard breather valve, we offer custom engineering support for integration into your battery pack design. Our team has experience supplying components to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, East Asia, Western Europe, Central America, Northern Europe, Southern Europe, South Asia, and the domestic Chinese market. This global reach means we understand diverse regulatory requirements and can adapt our products accordingly.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for standard breather valves?
A: For standard M12/M18/M22 black valves, lead time is 7–10 working days after order confirmation and payment. Large quantities (10,000+ pcs) may require 2–3 weeks. -
Q: Can you provide samples before mass production?
A: Yes, we offer free samples (up to 5 pcs) for evaluation. Shipping cost is to be covered by the customer. For custom designs, a sample mold fee may apply. -
Q: Is the valve waterproof? What IP rating does it meet?
A: The valve is designed to prevent water ingress under normal operating conditions. It meets IP67 equivalent when properly installed (protected against temporary immersion up to 1 meter for 30 minutes). -
Q: Do you support custom thread sizes or colors?
A: Absolutely. We can modify the mold to produce any thread size (e.g., M10, M16, etc.) or custom color. Minimum order quantity for custom options is 5,000 pcs. -
Q: What is the operating temperature range of this valve?
A: The PP-T30 material can withstand continuous temperatures from -40°C to +120°C. For higher temperature applications, we can recommend alternative materials (e.g., PA66+GF30). -
Q: How do you ensure consistent quality during mass production?
A: Our robotic arm injection molding cells are equipped with process monitoring systems. Every batch undergoes dimensional inspection, burst pressure testing, and airflow rate verification. We also provide a Certificate of Compliance with each shipment. -
Q: What is the MOQ for standard valves?
A: The minimum order quantity for standard black valves is 1,000 pcs. For custom designs, MOQ is 5,000 pcs. We can also accommodate trial orders of 500 pcs at a slightly higher unit price. -
Q: Do you ship to Southeast Asia? What are the shipping terms?
A: Yes, we regularly export to SE Asia. Shipping terms can be FOB Jiangsu/Shanghai/Shenzhen, CIF, or DDP depending on your preference. We work with reliable freight forwarders to ensure timely delivery.
