EN 593 references EN 558 for face-to-face dimensions and ISO 5211 for actuator mounting flange dimensions. It ensures that a valve from manufacturer A will have the exact same overall length and bolt pattern as manufacturer B, allowing for direct interchangeability without pipeline modifications.

Yes, our valves are designed to meet the same EN 593/EN 558 dimensional standards. However, we always recommend verifying the specific material temperature and pressure ratings for your application. We can provide cross-reference drawings upon request.

For standard EN 593 wafer/lug valves (DN50-DN300), our MOQ is typically 50 units per size. For larger diameters or specialized materials (Duplex, Monel), we can negotiate based on project needs. Sample orders are always welcome for qualification.

Every valve undergoes hydrostatic shell testing and pneumatic seat leakage testing per EN 12266. We provide material traceability certificates (EN 10204 3.1) and can arrange third-party inspections (SGS, Lloyd's) prior to shipment.

We commonly work on FOB (Tianjin/Xingang), CIF, or DDP basis. Lead times are 4-6 weeks for standard sizes and 8-12 weeks for large diameter or custom orders. We offer expedited production schedules for time-sensitive projects.

Yes, all standard valves come with a 12-month warranty against manufacturing defects. Extended warranties are available for critical infrastructure projects. We also maintain a spare parts inventory for quick replacements.
