JIS Standard Ball ValveOverview

JIS Standard Ball Valve Overview

The JIS Standard Ball Valve is an industrial valve designed and manufactured in strict compliance with Japanese Industrial Standards (JIS). It features flange or threaded connections, with its design, dimensions, pressure ratings, and material requirements fully adhering to relevant standards such as JIS B2003 and JIS B2071. The valve body is typically made of cast steel, stainless steel, or brass, and rapid opening and closing are achieved through a 90-degree rotation of the ball.This valve is fully compatible with Japanese standard pipeline systems (e.g., JIS B2220 flanges, JIS B0203 threads). It is widely used in shipbuilding, machinery, chemical industries, and Japanese-standard engineering projects, serving as a reliable fluid isolation and control device within the JIS standard system.

JIS Standard Ball Valve Features

1. Strict Compliance with JIS Standards:

The entire process adheres to standards such as JIS B2003 and JIS B2071, ensuring complete compatibility with Japanese standard pipeline systems in terms of face-to-face dimensions, flange sizes, pressure ratings, and material requirements.

2. Optional Dual Seal Structures:

Offers both soft seal (e.g., PTFE) and metal hard seal options, making it suitable for a wide range of applications, including water, steam, oil products, and corrosive media.

3. Easy and Safe Operation with High Reliability:

Provides rapid 90-degree opening and closing with low operating torque. Some models are equipped with fire-safe and anti-static designs, complying with Japanese safety standards.

4. Strong Connection Compatibility:

Flange connections conform to JIS B2220 standards, and threaded connections comply with JIS B0203 standards, ensuring excellent interchangeability with Japanese standard pipelines and certain international standard pipelines.

5. Easy Maintenance and Wide Application Range:

Designed for easy disassembly and maintenance, with replaceable sealing components. Suitable for shipbuilding, machinery manufacturing, chemical equipment, and Japanese-funded projects, offering high versatility.

Wafer-type ball valve patented

The utility model provides a wafer-type float valve, which includes a valve body and a driving mechanism. The valve body is provided with a through medium channel in the axial direction, and is tubular in shape. It also includes a butterfly plate that fits and seals with the inner wall of the medium channel. The driving mechanism comprises a valve shaft that passes through the valve body and is connected to the butterfly plate, a valve rod connected to the outer end of the valve shaft in the radial direction, and a float ball connected to the valve rod. The valve rod is provided with a limit bolt that is threadedly connected to the valve body in the swinging direction. The butterfly plate can rotate relative to the valve body. The front end of the valve body at the inlet of the medium channel is provided with a filter screen, which is hollow and hemispherical in shape. The end face of the valve body opposite the filter screen is provided with an annular groove, and the open end of the filter screen is provided with a raised edge that is embedded in the annular groove. The utility model can filter the medium, is simple to install, time-saving, labor-saving, small in size, widely applicable, and can reduce the impact force of the medium on the butterfly plate.
