Bubble Tight Bubble Tight Ball Valve for Critical Isolation

Distinguish material grades clearly before orders. 201 stainless steel is prone to rust in humid coastal environments; offer 304/316 for corrosive working conditions. We conduct pickling and passivation treatment on all valve surfaces to boost anti-rust performance.

Confirm working pressure, temperature and medium in advance. Match suitable PTFE/EPDM sealing gaskets. All valves undergo 100% water and air pressure leakage tests before shipment; provide test reports.

Confirm standard types (ANSI, DIN, GB, JIS) and connection forms (flange, thread, weld) at the quotation stage. Mark all dimension parameters on the sales contract and production drawings for double check.

Each valve is wrapped with plastic film and foam individually, then packed in plywood export wooden cases without fumigation. Fix internal valves with brackets to avoid collision.

Provide multiple shipping solutions: full container load (FCL) for bulk orders to cut unit freight; less container load (LCL) for small batches. Book shipping space in advance to lock lower freight rates.
