Import Flange End Ball Valve — Buy in Bulk from Supplier in China

The flange end ball valve from Wenzhou Wonston Valve Co., Ltd complies with JIS B2002 and ANSI B16.10 for face-to-face dimensions, and JIS B2220 and ANSI B16.5 for flange ratings up to Class 10K and 150LB. The body is manufactured using investment casting, ensuring consistent wall thickness and structural integrity under pressure. Pressure balance holes are integrated into the ball to reduce operating torque and prevent seat erosion during cycling.

The valve design follows ANSI B16.34 for pressure-temperature ratings and is tested per API 598 to verify seat leakage performance. Standard materials include CF8M stainless steel for the body and stem, with PTFE or RPTFE seats for sealing. These materials are typical for industrial applications requiring resistance to mild corrosion and moderate temperatures. The valve is available in full port and reduced port configurations, with standard bore sizes ranging from 1 inch to 6 inches.

This valve is commonly purchased by manufacturers in water treatment, chemical processing, and oil and gas sectors where tight shut-off and low torque operation are critical. Buyers typically order in quantities of 50 to 500 units, with packaging in wooden crates or cartons with foam inserts. Trade terms are usually FOB Ningbo or CIF, with lead times of 25 to 40 days depending on order volume. Certifications such as ISO 9001 are not stated in the listing and should be confirmed directly with the supplier.
