Product Description

API 609 Butterfly Valve

API 609 valves are often used to regulate flow in larger pipelines. A common example is butterfly valves. The standard guarantees effective functioning even in high-utility environments.

Butterfly valves usually consist of a valve body, valve disc (butterfly plate), valve stem and seals. The valve plate is located inside the pipe and can rotate along the axis of the pipe to control the flow of fluid. When the valve plate touch the valve seat, it can effectively prevent the flow of fluid.

Applications Of API 609 Butterfly Valve

1. Simple structure

Compared with other valves, the butterfly valve has a relatively simple structure, light weight and small size.

2. Quick opening and closing

The disc of the butterfly valve only needs to rotate 90 degrees, so it can be opened or closed quickly.

3. Low flow resistance

Since the valve disc of the butterfly valve rotates on the axis within the pipe, when it is fully opened, the resistance of the fluid is relatively small and has a lower pressure drop than most other valves.

4. High flow capacity

Butterfly valves usually have larger diameters, and ZFA valves can reach DN3000, which can control large flows.

5. Wide range of applications

Butterfly valves are suitable for low-pressure and medium-pressure systems, and are usually used to control media such as liquids, gases, and powders. The temperature range is usually based on the material and design of the butterfly valve.

6. Operation method

API 609 butterfly valve is usually operated by manual, pneumatic, electric or hydraulic methods.
