Stainless Steel Flanged Check Valve (JIS 10K / ANSI 150)
Description
Stainless Steel Flanged Check Valve (JIS 10K / ANSI 150) – Technical Datasheet
1. Product Overview
This product is a high-quality stainless steel flanged check valve designed to prevent backflow in industrial piping systems. As shown in the images, it features a robust spherical body, a bolted bonnet design, and flanged connections. The valve body is clearly marked with “SAVVY” (Brand), “SCS16” (Stainless Steel 316), “10K-150” (Multi-standard pressure rating), and a flow direction arrow. It is widely used in chemical, petrochemical, water treatment, and food processing industries, particularly for corrosive media and high-purity applications.

5. Key Features
-
Superior Corrosion Resistance: Manufactured from SCS16 (CF8M/SS316) stainless steel, providing excellent resistance to aggressive and corrosive media in harsh environments.
-
Multi-Standard Flange Compatibility: The flange dimensions and drilling are designed to be compatible with both JIS 10K and ANSI Class 150 standards (marked “10K-150” on the body), reducing inventory and installation complexity.
-
Robust Bolted Bonnet Design: The bolted bonnet structure ensures a secure, leak-proof seal and allows for easy maintenance and replacement of internal parts.
-
Clear Flow Indication: A prominent cast arrow on the valve body ensures correct installation orientation, preventing costly reverse-flow damage.
-
Low Pressure Drop: The streamlined internal flow path minimizes pressure loss and turbulence, optimizing system efficiency.
