18‑Inch Ball Valve
The 18‑inch Ball Valve is a trunnion‑mounted, heavy‑duty valve engineered for precision flow control in large‑diameter pipelines. Designed with double block and bleed capability, it ensures complete isolation by sealing both upstream and downstream sides while safely venting residual pressure. Available in stainless steel, carbon steel, and alloy materials, this valve is built to meet ASME B16.34 design standards and tested in accordance with API 6D/API 598. Its robust construction makes it ideal for demanding industrial environments requiring reliable shut‑off and safety under high pressure.
