A CAST STEEL BUTTERFLY VALVE is a type of quarter-turn valve used to regulate or isolate the flow of fluids in a pipeline. It is designed with a disc that rotates around a central axis to control the flow. When the disc is parallel to the flow, the valve is fully open, and when it is perpendicular, the valve is closed.

Key Features:
-
Material: The valve body is made from cast steel, which provides high strength, durability, and resistance to high pressure and temperature conditions. This makes it suitable for demanding industrial applications.
-
Design: The butterfly valve has a compact and lightweight design compared to other valve types, making it easier to install and maintain.
-
Disc: The disc, which controls the flow, is typically made of metal or lined with materials like rubber or polymer to enhance sealing and corrosion resistance.
-
Sealing: The valve offers tight sealing with the help of elastomeric seats, ensuring minimal leakage and reliable performance.
-
Operation: It can be operated manually, electrically, pneumatically, or hydraulically, depending on the application requirements.
Advantages:
-
Cost-Effective: Lower initial and maintenance costs compared to other valve types.
-
Quick Operation: The quarter-turn mechanism allows for fast opening and closing.
-
Versatility: Suitable for a wide range of pressures, temperatures, and fluid types.
-
Space-Saving: Compact design requires less space for installation.
