DIN Standard Cast Steel Flanged Ball ValveOverview

DIN Standard Cast Steel Flanged Ball Valve Overview

The DIN Standard Cast Steel Flanged Ball Valve is an industrial valve designed and manufactured in strict compliance with the German Industrial Standards (DIN) system. It features a cast steel body with standard flange connections. Its design, dimensions, pressure ratings, and material requirements fully adhere to relevant DIN standards, including DIN 3202 and DIN EN 1092. The valve body is typically cast from carbon steel or stainless steel and employs a floating or fixed ball structure, enabling rapid opening and closing through a 90-degree rotation of the ball.This valve is fully compatible with DIN-standard pipeline systems and is widely applicable across industrial sectors such as chemical processing, energy, water treatment, and machinery equipment. It serves as a reliable medium-to-high-pressure fluid control device within the DIN standard system.

DIN Standard Cast Steel Flanged Ball Valve Features

1. Strict Compliance with DIN Standards:

The design and manufacturing fully adhere to standards such as DIN 3202 and DIN EN 1092, ensuring seamless integration with German standard pipeline systems in terms of flange dimensions and pressure ratings (PN series).

2. Reliable Strength of Cast Steel Body:

The valve body is produced using precision casting technology, ensuring a dense structure and excellent mechanical properties, making it suitable for medium- to high-pressure industrial applications.

3. Excellent Sealing Performance:

Offers both soft seal (e.g., PTFE) and metal hard seal options, providing reliable sealing for water, steam, oil products, and mildly corrosive media.

4. Easy Operation and Maintenance:

The valve is lightweight and easy to operate with its 90-degree opening and closing mechanism. Some models are equipped with fire-safe and anti-static designs. The structure is designed for easy disassembly, resulting in low maintenance costs.

5. Wide Compatibility and Application Range: The flange connections are compatible with German standards and some international standards, making the valve widely applicable in industrial pipelines, mechanical equipment, and European standard projects, with strong 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.
