DIN Floating Standard Ball ValveOverview

DIN Floating Standard Ball Valve Overview

The DIN Floating Standard Ball Valve is an industrial valve designed and manufactured in strict compliance with German Industrial Standards (DIN), featuring a floating ball structure. The valve body is typically made of cast steel, stainless steel, or brass. Under the action of medium pressure, the ball can undergo slight floating displacement, pressing tightly against the outlet seat to form a self-sealing closure. Its design, dimensions, and testing requirements fully adhere to relevant standards such as DIN 3202 and DIN EN 1092-2. Quick opening and closing are achieved through a 90-degree rotation of the ball.This valve is fully compatible with DIN-standard pipeline systems and is suitable for water, steam, oil products, and non-corrosive media. It is widely used in chemical processing, energy, heating, ventilation, and industrial fluid control systems, serving as an economical and reliable general-purpose isolation device within the DIN standard system.

DIN Floating Standard Ball Valve Features

1. Strict Compliance with DIN Standards:

The design and manufacturing fully adhere to standards such as DIN 3202 and DIN EN 1092-2, ensuring complete compatibility with German standard pipeline systems in terms of flange dimensions and pressure ratings.

2. Floating Ball Self-Sealing Design:

Utilizes medium pressure to automatically compress the ball against the seat, creating a reliable seal. The simple and robust structure ensures excellent sealing performance.

3. Lightweight Operation and Quick Opening/Closing:

Full opening or closing is achieved with a 90-degree rotation. The valve features low flow resistance and low operating torque, and can be configured for manual or actuator operation.

4. Cost-Effective and Easy Maintenance:

The simple structure results in low manufacturing costs, while sealing components are easy to replace, ensuring low maintenance costs and high cost-effectiveness.

5. Wide Range of Applications:

Suitable for a variety of industrial media within conventional temperature and pressure ranges. It offers excellent compatibility with German and international standard pipelines, making it highly versatile.
