Benefits of having double flange butterfly valves:

1. Having double flanges makes it easier to install and replace.
2. Economical in pricing as it reduces the cost to buy and weld additional flanges

Why do Cement Industries use butterfly valves?

Processing plants use double flanged butterfly valves for intercepting gravity-fed or pneumatically conveyed dry materials. They install these valves beneath hoppers, bins, silos, screw or other type conveyors, or to intercept pneumatic conveying ducts. The special design and engineering materials used in these valves make them a particularly cost-effective yet efficient solution.

Mechanism of Pneumatic Actuated Butterfly Valve.

The pneumatic Butterfly valve works on a simple mechanism and is easy to use so it has low maintenance. These valves have a disc connected to a center rod that rotates the disc quarterly to open and close the valve. They are fitted in the middle of the fluid flow. A metal disc called butterfly will rotate a quarter turn to allow an indefinite fluid flow. And consequently the slow opening valve will reduce the flow and turning the disc will stop the flow completely.  This valve is operated by pressurized air which is controlled by a pneumatic actuator fixed on it. So there is no need of any personal to operate the valve. The pneumatic actuator operates this valve fast and easily at a lower cost and with greater safety.

Where to Use Pneumatic Actuated Butterfly Valves

People generally use Pneumatic Actuator Butterfly Valves for liquid and slurry materials. These valves are very popular in the valve industry because of their easy-to-use and simple mechanism. Pneumatic Butterfly Valves are very useful for controlling highly inflammable liquids, such as petro-chemicals, oil, and gas. They operate using a pneumatic mechanism, which allows for fast functionality and keeps them safe from fire and electric short circuits. As a result, they are electricity-efficient valves with the lowest cost.

Applications

Diverse industries and applications use butterfly valves, such as pharmaceuticals, chemicals and oil, food, water supply, wastewater treatment, fire protection, gas supply, fuel handling, and sanitary fittings. People use butterfly valves for water as control valves to manage water flow. These valves come in various sizes and are suitable for handling slurries and liquids that contain relatively large amounts of solids at low pressures. People use stainless steel butterfly valves in corrosive and marine environmental applications because the stainless steel material is highly durable and resistant to corrosion.
