The Usefulness of the Butterfly Valve

A valve is basically a device that initiates the movement in any kind of substance. Now, the substance can be in any form solid, liquid or gas. The apparatus itself controls the movements of the elements either by opening up or slightly blocking or rather completely closing the passageways. Such a device is put in use in almost every place. Be it for the residential use, business purpose, transportation facility or the industrial setting.

Valves are utilized in two different ways. Either by making use of the pressure as in the steam engines or can works in a regulated manner. They have got a chief role in the cyclic control of the engine of machines.

Now, there are a number of different types of valves available that are being put in use in different ways. The Motorized butterfly valve is one of the commonly used valves. It is especially put in the broad pipes. The disk revolves on the perpendicular axis within the pipes. They even function as a damper or the controlling valve. The valve acts as the apparatus controlling the movement of the liquid which is present in the different parts of the pipe.

Even this valve operates in the same manner as the ball valve. It contains a round-shaped plate which is perfectly placed in the mid of the pipe. The plate has got a bar inside which is accurately joined with the switch of the outer valve portion. In this valve both the handle and the plate function at the same time in a similar position. However, unlike the ball valves, this particular butterfly valve is always present in the move constantly. Hence a gradual drop in the pressure is always witnessed regardless of the position of the valve.

The Actuated Butterfly valves control the gaseous or liquid flow with the help of disk. It is always said to make a comparison among the different types of butterfly value and select from the series anyone which suits the requirements. Make sure to have a reliable functioning and high level performance valves in use.

Motorized butterfly valve and electric operated ball valve

The traditional butterfly valve never used a very tight closure. But after several years of development, now the butterfly valves have been manufactured along with a fairly tight seal. The same is made of the material such as rubber or elastomeric materials. These materials provide a good option of shut off, just like many other types of valves.

Motorized Butterfly valves also find its usage at the places where space is less. The butterfly valves can be used for regulating the flow, also like in full-open and closed position. It is also important to know that the pressure loss through a butterfly valve is much smaller than the gate valve. We must tell you that the L/D ratio for butterfly valve is one-third of the gate valve. Butterfly valves are used in many large and small sizes also. They are often hand wheel operated and sometimes also operated through a wrench or gearing mechanism.

The butterfly valve is a rotary valve in which there is a disk-shaped seating element which is rotated 90° so that the flow can be opened or closed. They find their application in the throttling service where large-size valves with automatic actuators are required. Butterfly valves cannot be used where there is a need for non - obstructed, full opening. As compared to the ball valve, they have better size and weight.

The butterfly valves can operate at a high-pressure drop, along with a metallic or soft disc. The butterfly construction can withstand high temperatures where the upper temperature can also be increased through a refractory lining. The butterfly valves are often used in low-pressure water service and throttling usage.

A ball valve is a type of quarter-turn valve. It uses a hollow and perforated ball to control the flow, and hence it is called as the ball valve.  It gets open when the hole in the ball comes in line with the flow and closes when it gets at a pivoted angle of 90 degrees. The handle remains flat as per the flow when open and is perpendicular when closed. You can easily get to know through its visual that what is the status of the valve.

The electric operated ball valve is easy to operate and easy to repair too. It is a versatile equipment, and hence it is ideal for extensive use by many industries. It can support the pressure of around 1,000 bar and also the temperatures up to 752 °F or 400 °C. Its size can start from 0.2 inches and go up to 48 inches. Valve bodies can be made of metal, plastic, ceramic, etc., and the floating ball can be chrome plated so that it lasts long.
