double flanged butterfly valve supplier and manufacturer

What is a double flanged butterfly valve?

The double flanged butterfly valve is a type of valve designed with two flanged ends one on the inlet and the other on the outlet end. The flanged ends have holes. This type of valve is connected to a pipe ends that have flanges and holes of the same size as the valve. Double flanged butterfly valve manufacturers design these valves for use in high-pressure applications since they are very strong. These valves are more expensive compared to other butterfly valves. These valves are operated manually or by use of actuators like electric, pneumatic or hydraulic actuators. Double flanged butterfly valves are operated by turning the valve disc for a quarter turn in the anticlockwise direction to allow fluid flow. The valve is closed by turning the disc in the clockwise direction. 

Double flanged butterfly valve manufacturers produce varieties of these valves which include manual double-flanged butterfly valves and actuated double-flanged butterfly valves among others. Factors to consider when purchasing a double-flanged butterfly valve are the type of media, operating temperature, and fluid pressure. These valves are used in various industries such as water supply, chemicals, foods and beverages, mining operations, paper and pulp, petroleum refineries, oil and gas, and firefighting applications among others. Advantages of using these valves are fast operation, manual or automatic operation, high strength, simple and compact design, small installation space, and easy to install and repair.

• Low head loss.

• Vulcanized seat that avoids the contact between fluid and cast iron, avoiding corrosion and damages.

• 100% water tight.

• Bidirectional flow.

• Polished disc borders to avoid damage in the seat.

• No gaskets needed for installation.

• Working temperature between -10ºC and 90ºC.

Advantages of double flanged butterfly valves 

Double-flanged butterfly valves are very strong compared to other butterfly valves. 

These valves need only a quarter turn to open and close and thus they are fast operating. 

They are free from fluid leakage. 

They are versatile as they can be used in different industries. 

They can be used in high-temperature applications. 

They are of simple and compact in design. 

Double flanged butterfly valves can be manual or automatic as necessary. 

These valves occupy smaller space when installed compared to other valves. 

They are easy to install, repair, and clean.

Disadvantages of double flanged butterfly valves 

These valves are heavy compared to other butterfly valves. 

When the valve is open the disc remains in the fluid flow path which reduces flow pressure. 

These valves are suitable for throttling use where pressure drop is low.
