Butterfly valve manufacturer in India

Category: Business

Specialityvalve is the greatest Butterfly valve manufacturer in India. A butterfly valve is a valve that isolates and consists of a rotating circular plate or a pair of hinged semi-circular plates, attached to a transverse spindle and mounted inside a pipe to regulate or prevent flow. The term “butterfly” in a butterfly valve is a disk that is connected to a rod. It is a motion like a butterfly that has wings that move up and down at 90 degrees. The butterfly valve is a metal disc framed on a rod. It is operated when the valve completely blocks the passageway and when it is open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened gradually to compress the flow. The components of butterfly valves are- the body, disk, stem, seat, gland, spacer, and internal springs. Functions of Butterfly Valves: when the butterfly valve is fully opened, it has a small flow resistance, the Butterfly valve is suitable for flow regulation, Butterfly valve has good fluid control characteristics. The butterfly valves come in two designs- centric and eccentric. The only difference between the two is, in centric the stem is placed in the center of the disc, and the disc is placed in the center of the bore. Whereas in eccentric, there can be more than one stem placed offset from the center. Types of butterfly valves: Zero Offset Butterfly Valve Double Offset Butterfly Valve Triple Offset Butterfly Valve Metal Seated Butterfly Valve Industries of butterfly valve: Chemical Industry Oil & Gas Industry Petrochemical Industry Energy Industry LNG & LPG Marine Industry Advantages of butterfly valve: It requires less material Simple to design and manufacture Wide variety to use in case of underground installation also Easy to Install Smooth to control.

A double offset butterfly valve is a control fluid flow in a pipe by using a disc attached to a central shaft. This disc controls the amount of fluid flow through the valve by creating a variable opening. Double-offset butterfly valves are also known as high-performance butterfly valves. Double-offset butterfly valves have two discs that can be used up to 1480psi. It can be operated manually using a handle, gears, and actuators. These devices rotate the valve disc to the ideal location for effective sealing or complete opening of the valve. It can be found in higher pressures compared to zero offset ones. The movement of a double-offset butterfly valve keeps a conic profile in sealing the valve. The arrangement of the offsets of the disc and the shaft generates an action of the disc into the seat which reduces the required torque to close or open the valves. They can survive extreme pressures and temperatures and are suitable for handling gas, oil, steam, and water in a lightweight and cost-effective design. Advantages of the double offsets butterfly valve It allows the disc to self-adjust Ensure tight sealing Durability Components of the double offset butterfly valve Body Seat Disc Shaft Bearing Seat retainer Industries of the double offset butterfly valve Chemical Mining Power generation Petrochemical Water filtration Available materials: Cast iron, Ductile iron, SS304, SS316, Carbon steel(Wcb, Wcc, wc9, wc6), SS316L, Duplex steel(F51,F53,5A,4A,6A) Size: 2” to 72” Class: 150 to 300 Nominal Pressure: PN6 to PN25 Ends: Wafer, Lug, Flanged Operations: Gear Operated, Electric and Pneumatic Actuated, Lever Standards: ASME, API6D, API607, DIN, BS, ANSI, AWWA Specialityvalve is proud of being a Double Offset Butterfly Valve Manufacturer in India which provides optimum quality valves and has genuine guarantee raw material with the testing and offers customized valves as per the requirements of the clients. https://www.specialityvalve.com/product-category/double-eccentric-butterfly-valve/
