Difference Between Manual Butterfly Valve And Pneumatic Butterfly Valve
- Клапан DELCO
Pneumatic butterfly valves и manual butterfly valves are commonly used types of valves, they play an indispensable role in industrial production. Although they are both butterfly valves, they have differences in the operation mode, control mode, structural form and application areas, this article by DELCO Valve for you to do a detailed introduction.
Operation Mode
The operation mode of manual butterfly valve is to control the switch of the valve by manual wheel or handle, which needs manual operation. The operation is simple and flexible, but it requires larger force to operate the valve of large caliber. And pneumatic butterfly valve is through the pneumatic device to control the switch of the valve, the operation is convenient, fast, only through the electrical signal or manual switch to control, without manual operation.
Control Mode
The control mode of manual butterfly valve is relatively single, only through manual operation to control the valve switch. The pneumatic butterfly valve can realize the control of the valve through a variety of control methods, such as electrical signals, manual switches, PLC and so on.
Структура
Manual butterfly valve structure is simple, easy to maintain, due to its manual operation limitations, generally only applies to small diameter valves. While the pneumatic butterfly valve structure is relatively complex, but due to the special nature of its operation mode, it is suitable for a variety of caliber valves. The structure of pneumatic butterfly valve is mainly composed of three parts: pneumatic actuator, regulating mechanism and butterfly plate.
Application
Manual butterfly valve is suitable for some small equipment or equipment that does not require frequent operation, such as low-pressure air pipeline, low-pressure water pipeline and so on. And pneumatic butterfly valve is suitable for high pressure and large caliber pipeline system, such as petroleum, chemical, electric power and other fields because of its fast, accurate and reliable characteristics.
Заключение
Pneumatic butterfly valves have advantages over manual butterfly valves in terms of operation mode, control mode, structure form and application area. However, the price of pneumatic butterfly valve is relatively higher, and the maintenance is also more complicated, requiring professional personnel to operate and maintain. Which type of butterfly valve to choose needs to be decided according to the specific requirements of use, according to the required operation, control, safety and other requirements, choose the type of valve that suits you in order to better play its role in the production process.
