The Butterfly Valve is a device that regulates and isolates the flow of a fluid. Its closing mechanism is a disk that rotates. The Butterfly Valve has a variety of uses, including in food and beverage processing, air conditioning, and water treatment. Its primary function is to regulate the flow of fluid.The Eccentric Butterfly Valve has an open and closed design that is ideal for controlling pressure and flow. It features multiple O-ring shaft seals to isolate process media from internal components. In the closed position, the sealing ring is held in place by a retaining ring, which prevents it from rolling out. The seal ring is pressed against the seat face, providing a tight seal at both upstream and downstream ends.

The valve's double eccentric disc design also allows it to be operated manually or through an electric, pneumatic, or hydraulic actuator.A Concentric Butterfly Valve is designed to maintain a tight seal against a bi-directional pressure differential. The butterfly valve is ideal for applications where backflow is a concern. The valve's flat valve face, tightly fitting seal, and threaded inserts on both sides of the valve body prevent backflow. Its long-neck construction and interchangeable components allow for easy assembly and dismantling.Butterfly valves are two-way inline valves that are used for flow control. They are typically made of metal, and are positioned on a rod.


When the valve is open, the butterfly/metal disc on the valve moves at a 90-degree angle to allow fluid to pass.Hastelloy Butterfly Valves are designed with multiple advantages. They are lightweight, have a low torque requirement, and are maintenance-free. They are also available with a variety of materials and features. They are ideal for applications requiring low-pressure, high-volume gas flow control.A brass butterfly valve is a valve made of brass, an alloy of copper and zinc. It is a tough and durable material that can withstand high temperatures. It also has antimicrobial, anti-corrosion, and biofouling properties.


These properties make brass butterfly valves ideal for applications in wastewater treatment, water purification, and food manufacturing. However, they should not be used in highly chlorinated water because the chlorine will dezincify the brass.Electric actuated soft seated butterfly valves provide on-off control of air, oil, or other media. They are generally sandwich mounted between two ANSI / ASME Class 125 / 150 flanges. The standard unit has a power-to-open and power-to-close function. It maintains its last known position even in the event of a power failure. A motor rotates the disc, allowing it to close and open with minimal or no manual operation.The Pneumatic Butterfly Valve is an industrial valve that uses a pneumatic propulsion method. This valve has many advantages including small size, low weight, and easy maintenance. This valve can be used in a variety of industrial fields.
