ASME Standard Flange Connection Industrial Stainless Steel Ball Valve

When selecting industrial valve solutions, compliance with stringent standards and robust construction are paramount. Our ASME Code Flanged End Elevated Platform Stainless Steel Ball Valve is engineered for critical applications requiring reliable shut-off and ease of maintenance. Featuring a high-rising stem and an elevated platform, this valve allows for efficient operation in demanding environments. For systems where corrosion resistance is a primary concern, the High Platform Corrosion-Resistant Steel Ball Valve with ASME Standard Flange offers superior durability against aggressive media. Both valves are designed with precision-engineered, full-port bores to minimize pressure drop and ensure optimal flow control. Their construction adheres to ASME B16.5 and B16.34 standards, guaranteeing dimensional interchangeability and pressure integrity, making them ideal for use in chemical processing, petrochemical, power generation, and other heavy industries.


The ASME Standard Flange Connection Industrial Stainless Steel Ball Valve represents a pinnacle of industrial fluid control design. Crafted from high-grade 316 stainless steel, it provides excellent resistance to oxidation, pitting, and a wide range of corrosive chemicals. The valve's key operational features include a quarter-turn actuation for quick open/close cycles, a blow-out-proof stem for enhanced safety, and reinforced PTFE seats for reliable sealing across a broad temperature range. The integrated ASME standard flanges, available in classes such as 150, 300, and 600, ensure a leak-proof connection to existing piping systems without the need for adapters. Below are the detailed technical specifications and dimensional data for this valve series.
