SVR Global is the best Butterfly valve manufacturer in USA. A butterfly valve is used to regulate the flow of fluid in a process system. It consists of a circular disc or plate that is mounted on a shaft in the center of the valve body. The disc can be rotated by a handle or an actuator, which causes the disc to move in a plane perpendicular to the flow direction of the fluid. When the disc is rotated parallel to the direction of fluid flow, it allows full flow of the fluid through the valve. When the disc is rotated perpendicular to the flow direction, it blocks the flow of fluid completely. The degree of rotation of the disc determines the amount of fluid flow. SVR Global, the Butterfly valve manufacturer in USA manufacture valves that are widely used for waste water, fire protection and in gas supply industries as well. Parts: • Valve Body: This is the outer shell of the valve that houses the internal components and provides the flanged or threaded connections for installation in the pipeline. • Disc or Vane: This is the component that rotates within the valve body to regulate the flow of fluid. • Stem: This is the shaft that connects the disc or vane to the actuator, allowing it to be rotated to control the flow of fluid. • Actuator: This is the component that provides the motive force to rotate the disc or vane. Actuators may be manual, such as a handwheel or lever, or they may be automated using electric, pneumatic, or hydraulic power. • Bearings: These are the components that support the stem and allow it to rotate smoothly within the valve body. Bearings may be made of metal, and they may be lubricated or self-lubricating for reduced friction and wear. • Seals: These are the components that prevent leakage between the valve body and the disc or vane. • Bolts and Nuts: These are the fasteners that hold the valve body and flanges together, creating a secure seal between the valve and the pipeline. Bolts and nuts may be made of metal, and they may be coated or lined for corrosion resistance. Types of Butterfly Valves: • Wafer Butterfly Valve: This type of valve has a simple design and is compact in size, making it easy to install between flanges. It is suitable for low-pressure applications and is commonly used in water treatment, and chemical processing systems. • Lug Butterfly Valve: This type of valve has threaded inserts on the valve body, allowing it to be bolted between two flanges. It is commonly used in higher-pressure applications, and it is often preferred for applications where frequent disassembly is required. • Buttweld Butterfly valve: it has a pair of buttwelded ends that allow for easy installation and connection to other pipeline components. • Concentric butterfly valve: A concentric butterfly valve is designed with a disc that is centered in the middle of the valve body. • AWWA Butterfly valve: AWWA butterfly valves are typically constructed with a circular disc that rotates around a central axis to control the flow of water through the valve. • Triple Offset Butterfly Valve: This butterfly valve has a complex design that uses a triple offset to create a metal-to-metal seal, eliminating the need for a soft seal. It is suitable for high-temperature and high-pressure applications, and it is commonly used in power generation and petrochemical industries. • Double Offset Butterfly Valve: Similar to a double eccentric butterfly valve, a double offset butterfly valve has a disc that is offset from the centerline of the valve seat and the stem. • Flanged Butterfly Valve: A flanged butterfly valve is a type of butterfly valve that has flanged ends, which allow it to be bolted between two flanges. This type of valve is commonly used in applications where a tight seal is required and frequent disassembly is not necessary. Industries: ● Chemical Industry ● Oil & gas Industry ● Petrochemical Industry ● Technical gases ● Energy industry ● Textile industry ● Water and wastewater industries Applications: ● Water treatment: Butterfly valves are used in water treatment plants to control the flow of water through pipes and channels. ● Chemical processing: Butterfly valves are used in chemical processing plants to control the flow of corrosive or hazardous fluids through pipes. ● Oil and gas: Butterfly valves are used in the oil and gas industry to control the flow of crude oil, natural gas, and other fluids through pipelines. ● Power generation: Butterfly valves are used in power plants to control the flow of steam or water through turbines and other equipment. Advantages: ● Quick and easy operation: Butterfly valves can be opened and closed quickly with just a quarter turn of the handle, making them ideal for applications where rapid flow control is necessary. ● Low maintenance: Butterfly valves have a simple design with fewer moving parts than other types of valves, making them easy to maintain and repair. ● Lower cost: Butterfly valves are generally less expensive than other types of valves, making them a cost-effective solution for many applications. ● Space-saving design: Butterfly valves have a compact design that requires less space than other types of valves, making them ideal for applications where space is limited. ● High flow capacity: Butterfly valves have a larger flow capacity than other types of valves, allowing for greater flow rates and improved efficiency.
