DIN Standard Check Valve

The DIN standard check valve is made of high-strength materials such as WCB cast steel, Monel alloy, and special alloys, strictly adhering to EN 13709 and DIN standards in design, ensuring structural strength and long-term reliability under various harsh working conditions.

Sealing Performance

The cobalt-based carbide (Co-carbide) sealing surface, combined with precision grinding technology, achieves zero leakage closure, effectively ensuring the purity of pipeline media and system safety.

Compatibility

The entire product range complies with German industrial standards (DIN), allowing seamless integration with valves, flanges, and fittings of the same standard, simplifying system deployment.

Durability

Impact-resistant materials and anti-corrosion processes work together to significantly enhance resistance to chemical media, environmental stresses, and physical wear, extending service life by over 30%.

Q&A

Q1: What is your Minimum Order Quantity (MOQ)?

A1: We do not enforce a Minimum Order Quantity (MOQ). We are flexible and can accommodate orders of any size, even for a single unit. For instance, we have previously supplied individual safety valves to meet specific customer needs.

Q2: Can you manufacture products according to standards other than your default ones?

A2: Absolutely. We can produce valves to meet various international or customer-specific standards. Simply provide the required standard specifications (e.g., ANSI, ASME, BS, JIS) with your inquiry, and we will confirm feasibility.

Q3: What is your typical lead time for providing a quotation?

A3: Our standard quotation turnaround is within 24 hours for common valve types. For inquiries involving special designs, non-standard materials, or complex specifications, it may take up to 48 hours to prepare a thorough and accurate quote.

Q4: Can you provide technical drawings for the inquired valves?

A4: Yes, we can provide general arrangement drawings upon request. Please note that preparing these drawings requires additional engineering time, so we advise factoring this into your schedule. However, for highly specialized valves, extremely wide pressure/class ranges, or types we do not typically produce, we may not be able to supply drawings, as no single factory manufactures every possible valve variant.

Q5: How are your products packaged for shipment?

A5: Standard packaging involves secure wooden cases. For larger or heavier valves, we use palletized packaging wrapped with protective film to ensure safe transportation and handling.

Q6: Do you produce check valves compliant with DIN standards?

A6: Yes, we manufacture check valves designed to meet relevant DIN standards (such as DIN 3356 for wafer check valves or other applicable norms). We can discuss specific type, pressure rating (PN), material (e.g., cast iron, carbon steel, stainless steel), and end connection requirements.

Q7: What are common materials and pressure ratings for your DIN check valves?

A7: We commonly use materials like cast iron (GG25), ductile iron, carbon steel (WCB), and stainless steel (CF8/CF8M). Standard pressure ratings include PN10, PN16, PN25, and PN40, with other ratings available upon request.

Q8: What is the typical lead time for an order of DIN standard check valves?

A8: Lead time depends on order quantity and specifications. For standard configurations, production typically takes 4-6 weeks after order confirmation. Non-standard materials or sizes may require additional time, which we will confirm during the order process.

Q9: Do your DIN check valves come with full certification?

A9: Yes, we can provide standard material test certificates (e.g., EN 10204 3.1). For specific certifications like pressure test reports or third-party inspection, please advise in advance so we can accommodate the request.

Q10: Can you customize DIN check valves for specific applications?

A10: Within the framework of the DIN standard, we can often accommodate modifications such as special trim materials, alternative coatings, or non-standard dimensions. Please share your detailed requirements for evaluation.
