Manual Butterfly Valves are a common option for simple applications where the cost of the valve and its operation is important. These valves have a basic structure and use a round plate as the closing part that is fixed on a rod. To adjust the flow through the pipeline, an external actuator—such as a hand wheel or gear—rotates the disc. Butterfly valves are small from face to face and take less area to install than other types of valves. They are also easy to maintain and install. However, because of its high rate of leakage and difficulty to accurately set the disc, manual butterfly valves are not suitable for operations needing tight shutting down or control. For low-pressure situations which need to be adjusted or rarely handled, these valves are suitable. Because of their low price, ease of use, and convenience of use, manual butterfly valves continue to be a common option in a variety of industries, like food and beverage, pharmaceutical, water treatment, and HVAC, even with their limitations.
Moreover, a variety of components, including PVC, cast iron, and stainless steel, are available for manual butterfly valves in order to fit a range of media outlets, situations, and tasks. The materials used in construction are defined by the particular application, which includes parameters like temperature, pressure, and whether the fluid is transported is acidic or tough. The act of lubricating and adjusting the actuator connection on a regular basis is a requirement of manual butterfly valves.

CONCORDE VALVES AND AUTOMATIONS provides wide range of High performance Valves, these type of valves are prefered by clients for its heavy-duty, automatic throttling control flow for applications involving large flow rates and moderate pressure drops. It incorporates the two basic features of the high performance butterfly valve types: a PTFE, RTFE, or metal seal ring instead of a liner and double offset (eccentric operation) to reduce seal friction and operating torque and provide superior performance .We provide some of the high performance valves like Handle Operated Spherical Disc Valve and Worm Gear Operated Spherical Disc Valve too.
Spherical Disc Butterfly valves are also known as High Performance Butterlfy valves due its toughness & rigidity. The reason why they are termed as HIGH PERFORMANCE category is because it can with stand Temperatures Ranging from -25 0 C to 1800 C for soft seating & -25 0 C to 6000 C for Metal to Metal seat. Spherical disc butterfly valve can handle liquid fluid in large amount. Its specific rotational structure and sealing surface provides the self-cleaning function of the valve. It has a long working life due to its specially designed parts, which can crush solid particles smoothly.That is why they are used in pipeline control application such as high water tank, piping network, sewage system or any other backflow preventing system.
The Design of the Disc is Double Eccentric in nature. They come is various grades of metals like WCB, SS 304, SS316. The best part is that the valve is fully metal to metal apart from just PTFE seal which ensures Tight shut off & gives Class 6 leakage possibility. The Spherical Disc Butterfly valve can be operated by LEVER, GEAR, PNEUMATICALLY & ELECTRICALLY.

A mechanical instrument used for moving or controlling a system or mechanism is called an actuator. As part of the butterfly valve manual actuator, it is normally actuated by a mechanical device that transforms energy, which is usually produced by liquid, air, or electricity—into movement.
A butterfly valve is a type of flow control valve where the plate of metal has a disk-like shape. The method by which it operates is like a ball valve. In the exact center of the pipe is a plate or disc. A rod that is attached to an actuator outside the actuated butterfly valve goes through the disc. The disc can be rotated so that it runs either parallel or perpendicular to the flow by rotating the actuator. As opposed to a ball valve, which is continuously out of the flow, a disc valve generates a pressure drop in the flow no matter the valve's position.
Using a disk that rotates on a diametric spindle inside a pipe or two semicircular plates mounted on a common spindle to allow flow in only one direction, a butterfly valve manual actuator manages the flow of gas or liquid. With a small design, these actuated manual butterfly valves have a spinning head movement of 90 degrees or less. Butterfly valves don't have any gaps where fluids could get stuck when the valve is closed, when compared to ball valves.
Manually Operated Butterfly valve can be turned by a hand wheel, a crank, or lever. Typically, smaller manual valves have a lever attached. Hand wheels are included with bigger sizes, and they work in combination with a gearing to transfer torque with a strong mechanical boost.
