Standard body material: brass HPb57-3 (GB/T 5231; Cu 56–58%, Pb 2.5–3.5%).

Surface finish: valve body nickel-plated.

Other grades: HPb59-1 (GB/T 5231), CW617N (CuZn40Pb2; EN 12164 / EN 12165) and CW602N dezincification-resistant brass. All three are available on request and must be stated on the order. We do not substitute a different grade without your written approval.

Minimum order quantity: applies to all four grades.

Lead content: all four are leaded brass. HPb57-3 carries 2.5–3.5% lead, CW617N and CW602N 1.6–2.5%, and HPb59-1 0.8–1.9%. For potable water, confirm the lead-leaching limits of the destination market before ordering.

Material certificate: EN 10204 3.1 on request. The grade stated on the certificate governs.
