Product Introduction
A lug type butterfly valve with an extension stem is a type of valve commonly used in industrial applications to control the flow of fluids in a pipeline. Here are some key features and information about this type of valve:
Valve Design: A lug type butterfly valve has a disc or plate that rotates on a central axis to control the flow of fluid. The disc is connected to a stem, and when the stem is turned, the disc either blocks or allows the flow of fluid.
Lugs: The lug design refers to the presence of lugs or protrusions on the valve body. These lugs are typically located on the outer edges of the valve and serve as attachment points. They allow the valve to be installed between two flanges using bolts or studs.
Extension Stem: An extension stem is an optional feature that provides additional length to the valve stem. It allows the operator to reach and control the valve in applications where the valve is installed in a deep, buried, or hard-to-reach location. The extension stem protrudes from the top of the valve, providing access for manual or automated operation.
Materials: The materials used for the valve body, disc, stem, and extension stem can vary depending on the specific application requirements. Common materials include cast iron, ductile iron, stainless steel, and various alloys, chosen for their durability and resistance to corrosion.
Applications: Lug type butterfly valves with extension stems are commonly used in a wide range of industries, including oil and gas, water treatment, chemical processing, power generation, and HVAC (heating, ventilation, and air conditioning) systems. They are suitable for both on/off and throttling applications.
Advantages: Lug type butterfly valves are known for their compact design, ease of installation, and low-cost compared to other valve types. The extension stem further enhances their versatility by allowing for remote operation and control in challenging environments.
It's important to note that specific details, such as size, pressure rating, temperature range, and other technical specifications, will vary depending on the particular valve model and manufacturer.
