从China供应商批量进口3pc Screwed Ball Valve, Stainless Steel/Wcb

This 3-piece screwed ball valve from Wenzhou Ruisituo Valve Co., Ltd. is engineered for industrial fluid control with sizes from 1/4" to 4". The valve body is available in stainless steel grades 201, 304, and 316, or WCB carbon steel, offering corrosion resistance for harsh environments. Threaded connections ensure a secure, leak-proof seal, while the straight-through channel design minimises flow resistance, improving efficiency in piping systems.

The valve’s construction uses investment casting for precision, with a full-port or reduced-port configuration depending on the application. Stainless steel variants meet ASTM A351 for CF8/CF8M compositions, while WCB adheres to ASTM A216. The valve seats are typically PTFE or RPTFE for chemical compatibility, with a standard pressure rating of PN16 to PN40 or Class 150 to 300. Surface finishes are usually Ra 0.8 to 1.6 µm for smooth operation.

Common applications include oil and gas pipelines, water treatment plants, and chemical processing, where reliable shutoff and flow regulation are critical. Buyers in these sectors source these valves for their durability and ease of maintenance. The supplier’s address in Longwan District, Wenzhou, positions it near major ports, facilitating logistics for bulk orders. Confirm packaging, which is typically cartons or wooden crates, and lead time directly with the supplier.
