JIS Ball Valve – China Manufacturer & Supplier

Premium Quality JIS Ball Valves from China

As a professional China JIS ball valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance ball valves that fully comply with Japanese Industrial Standards (JIS). Our JIS ball valves are engineered to provide reliable on/off flow control with quarter-turn operation, bubble-tight sealing, and exceptional durability—making them the preferred choice for industrial piping systems across Japan, Southeast Asia, and global markets where JIS standards are specified.

JIS ball valves are designed to meet the specific requirements of Japanese and Asian industrial infrastructure, particularly in shipbuilding, chemical processing, and water treatment sectors. Unlike ANSI or DIN standards, JIS ball valves utilize metric units and feature flange dimensions and pressure ratings that are tailored to fit Japanese pipe systems.

JIS Standards & Technical Specifications

Our JIS ball valves are manufactured in strict accordance with the relevant Japanese Industrial Standards. The primary standards governing our products include:

• JIS B2071:2000 – Steel valves (general specification for steel ball valves)

• JIS B2051:1994 – Malleable iron 10K screwed valves

• JIS B2031:1994 – Gray cast iron valves

• JIS B2002:1987 – Face-to-face and end-to-end dimensions of valves

• JIS B2003:1994 – General rules for inspection of valves

JIS Ball Valve vs ANSI vs DIN: Key Differences

Understanding the differences between JIS, ANSI, and DIN standards is crucial for proper valve selection:

JIS flanges are not directly interchangeable with ANSI or DIN flanges without special adapter flanges or gaskets. This makes it essential to specify the correct standard when procuring valves for JIS-compliant piping systems.

Superior Design Features

Our JIS ball valves are engineered with precision and reliability in mind:

• Floating ball or trunnion mounted configurations to suit different pressure requirements

• Full bore or reduced bore options

• Blow-out proof stem design ensuring safety and reliability

• ISO 5211 mounting pad for direct actuator mounting

• Fire-safe and anti-static design available upon request

• PTFE/RPTFE seat seals for bubble-tight shut-off
