Hard seal butterfly valve, also called flap valve, is a kind of regulating valve with simple structure, and can also be used for switching control of low-pressure pipeline medium. Hard seal butterfly valve is mainly used to cut off and throttle the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting. Hard seal butterfly valve is suitable for pipes conveying corrosive and non-corrosive fluid media in producer, gas, steam, natural gas, city gas, cold and hot air, chemical smelting engineering and power generation environmental protection system, and is used to regulate and cut off the flow of media. Hard seal butterfly valve can be divided into manual hard seal butterfly valve, pneumatic hard seal butterfly valve and electric hard seal butterfly valve.
Wafer butterfly valves offer several features that make them an ideal choice for a variety of applications. First, they are designed for maximum efficiency and reliability by providing tight shut-off without the need for additional seals or packing materials.
Additionally, they feature low torque requirements while still achieving high flow rates. Furthermore, wafer butterfly valves typically come with a built-in positive sealing system, which helps ensure proper operation regardless of temperature changes or pressure fluctuations Another benefit is their easy installation due to their compact size and two-piece design which eliminates the need for welding or any other specialized equipment. Their design also makes them suitable for most media such as liquids, gases, and steam, making them an ideal solution for many industrial applications.
Wafer butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points. Hey provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary. Wafer butterfly valves are relatively simple to install and operate, making them a popular choice for many applications. In this article, we'll explore the basic workings of wafer butterfly valves, different types available, installation tips and more.
These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.
When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.
