A lug type butterfly valve is a type of butterfly valve that is held in place between two flanges using threaded bolts or studs, which are positioned parallel to the valve’s centerline.
The valve features a circular disc that rotates on a spindle or shaft to control the flow of fluid through the pipeline. When the valve is fully open, the disc is perpendicular to the flow path, allowing for maximum flow. When the valve is closed, the disc is parallel to the flow path, preventing the flow of fluid.
The lug type butterfly valve is designed to provide a secure and reliable connection to the pipeline, without the need for additional support or anchoring. The valve can be installed and removed from the pipeline without disturbing the adjacent piping or flanges.
Lug type butterfly valves are commonly used in applications where frequent maintenance or repair is required, such as water treatment plants, chemical processing plants, and HVAC systems. They are also used in applications where space is limited or where weight is a concern.
When selecting a lug type butterfly valve, it’s important to consider the specific requirements of your application, including the valve size, pressure rating, and temperature range. China lug type butterfly valve manufacturer It’s also important to choose a reputable manufacturer that provides high-quality products and reliable technical support.
What factors should I consider when selecting a lug type butterfly valve?
When selecting a lug type butterfly valve, there are several factors to consider to ensure that you choose the right valve for your application. Here are some key factors to keep in mind:
Valve size and flow capacity: The valve size and flow capacity should be selected based on the maximum flow rate required for your application.
Operating pressure and temperature: The valve should be rated for the maximum operating pressure and temperature of your application.
Valve material: The valve material should be compatible with the fluid being handled and the operating conditions of your application. Common materials include stainless steel, carbon steel, and ductile iron.
Disc material: The disc material should be selected based on the compatibility with the fluid being handled and the operating temperature of your application. Common materials include EPDM, Viton, and PTFE.
End connection: The valve end connection should be compatible with the flanges used in your piping system.
Actuation method: The valve can be operated manually or with an actuator. If an actuator is used, you should consider the type of actuator, such as electric, pneumatic, or hydraulic, and the required torque or force.
Application requirements: Consider any specific requirements of your application, such as bi-directional flow capability, fire-safe design, or low leakage.
Manufacturer reputation and support: Choose a reputable valve manufacturer that provides technical support and service for their products.
By considering these factors, you can select a lug type butterfly valve that meets the specific needs of your application and provides reliable and efficient flow control.
