Frequently Asked Questions

What standards and connection types are available for Wanlian valves?

Wanlian valves are manufactured to GB, ANSI, DIN and JIS standards on request. Flanged, grooved, wafer and threaded connections are available depending on the model. Tell our engineers your DN/PN and connection type in the inquiry and we will confirm the matching configuration.

What materials are used for the valve body and sealing?

Bodies are typically ductile iron (QT450), cast iron or cast/forged steel depending on the model. Sealing elements use EPDM or NBR rubber, and stems are stainless steel (2Cr13/304). Material options can be customized for specific media and temperature ranges.

What is the MOQ and lead time?

Standard MOQ is typically 20 units per model for stock sizes, with production lead times of 15-30 days depending on quantity and customization. Sample orders are available for pre-shipment testing.

How are the valves tested before shipment?

Every valve undergoes 100% shell and seat pressure testing in accordance with the applicable standard (e.g. GB/T13927, EN 12266-1). Test reports and third-party inspection can be arranged on request.
