Sanitary Weld-Thread Butterfly Valve

This hybrid butterfly valve features a butt-weld end on one side and a threaded end on the other, specifically engineered for pipelines that require permanent leak-proof sealing on one side and convenient maintenance access on the other. It is widely used in food, beverage, pharmaceutical and AI liquid-cooled data center fluid systems where one side connects to fixed process piping and the other needs periodic disassembly for cleaning or component replacement. As a real sanitary valve manufacturer established in 2003, KINGMAN operates a 5,000 m² facility with 48 MAZAK CNC lathes and 10 machining centers, producing over 2,000 valves per day and 2 million+ units annually. We can customize the weld-to-thread configuration to match your piping layout.

The one-end-weld one-end-thread design combines the best of both connection types: the welded side provides a permanent, leak-proof, joint-free connection for stable long-term operation, while the threaded side allows quick disassembly for maintenance, inspection or component replacement without cutting the pipeline. This hybrid configuration is particularly valuable in systems where one side connects to fixed process equipment and the other needs periodic servicing. The body and disc are CNC precision-turned to ensure accurate dimensions on both ends.

Every unit passes 100% in-house inspection before shipment — material spectral analysis, air-tightness test, hydrostatic pressure test, surface-finish/cleanliness check, cycle-life test and full appearance inspection. Products are manufactured under an ISO 9001 quality management system and to applicable hygienic standards including 3A, SMS, DIN and ISO. Our in-house laboratory performs material spectral analysis, sealing performance tests, hydrostatic pressure tests, product pressure-holding tests and surface-finish verification. Full inspection reports and material certificates can be supplied with each shipment, providing complete traceability from raw material to finished valve.

Standard stocked items ship within 7 working days; custom or non-standard configurations take 7–15 days; full-container bulk orders run 15–30 days and can be scheduled around your vessel. Urgent samples can be ready in 72 hours. Sample and small-batch trial orders are welcome — you can start with samples to evaluate workmanship, connection compatibility and product fit before moving into regular purchasing. For long-term stable volume orders, we offer tiered pricing and channel partnership programs. Our 5,000 m² facility with automated polishing lines and 48 MAZAK CNC lathes supports scalable production from prototype to full-container orders.

All export orders come with a 1-year international warranty plus lifetime technical support. Non-artificial damage within warranty is covered with free replacement or spare parts, backed by remote troubleshooting and installation guidance. We support EXW, FOB, CIF and CFR trade terms, work with your nominated freight forwarder, and accept sample orders, small trial batches and LCL/FCL shipments. Our experienced export team handles customs documentation, packing and logistics coordination to ensure smooth delivery to your destination. For distributors and equipment manufacturers with ongoing project schedules, we can arrange flexible production planning and reserved production capacity to support your recurring sourcing needs.

Standard body and disc construction is 304 / 316L stainless steel (AL6XN, Hastelloy, Alloy 22 available on request). EPDM is the standard seat seal, with PTFE, FKM (Viton) and silicone available to match specific temperature, chemical-compatibility and regulatory needs. The valve can be supplied with a manual multi-position locking handle for local isolation and throttling, or a pneumatic actuator for remote and automated on/off control. Higher alloys including AL6XN, Hastelloy and Alloy 22 are available for aggressive media.
