ASTM A105N Fixed Ball Valve, API 6D, 20 Inch, CL150, 3PC, RF

Key Specifications / Features

The ASTM A105N Fixed Ball Valve Manufacturer specializes in producing high-quality 3-piece trunnion-mounted ball valves that adhere to API 6D standards. These valves are crafted from forged carbon steel, ensuring exceptional strength and durability. With a 20-inch (DN500) diameter and rated for Class 150 LB (PN20) pressure, these valves are designed for demanding industrial applications. The RF flanged ends provide secure and reliable connections.

Trunnion Mounted Ball Valves offer easy and smooth operation under high line pressure, thanks to carefully aligned bearings that ensure low-torque operation. The ball is securely fixed yet free to turn, providing precise flow control. Manufactured from high-quality castings, these valves are certified for fire-safe design according to BS 6755, API 607, and API 6FA, and meet all applicable ASME standards. Available in Two Piece Split Body and Three Piece Bolted Body configurations, they are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351. Standard features include fire-safe, anti-static, and stem blow-out proof capabilities, making them ideal for a wide range of industrial applications.
