Pipe fittings are widely demanded for any piping and plumbing systems used in industrial and commercial applications. Fittings allow pipes to be joined or installed in the appropriate place and terminated or closed where necessary. Fittings are available in various shapes and sizes. They can be expensive, require time, and different materials and tools to install. They are an essential part of piping and plumbing systems. There are thousands of specialized fittings manufactured. Each type of pipe or tube requires its own type of fitting, but usually all pipe fittings share some common features. Pipe fittings are available everywhere where plumbing materials are sold.

Coupling fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter. Our range of coupling fittings are available in aluminium, steel and bronze.
Pipe couplings are highly demanded in the pipe fitting market. Pipe couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes. Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.

Pipe reducer are tube fittings that are widely used in a number of industries in order to providing greatest connection flexibility in connecting fractional tubes in various installations. Pipe reducer is a kind of pipe fitting that joins two pipes of different diameter. The pipe reducers are available in a range of materials depending on the end use of the products and these fittings are manufactured in inch and metric size.
Pipe reducers are special type of tube fittings that are commonly used in the demanding environments of chemical and power plants. They provide a highly reliable, sturdy and tight integral line system and these type of pipe fittings remain unaffected by shock, vibration or thermal distortion. These pipe fittings are very easy to install and they resist leakage due to thermal or pressure cycling. These reducers are sometimes chrome or nickel coated to prevent corrosion and increase the life of the product.
An Eccentric reducer, also called a Bell reducer, has two female (inside) threads of different sizes with centers so designed that when they are joined, the two pieces of pipe are not in line with each other, but they can be installed so as to provide optimum drainage of the line.

Uses of Globe valves:
Globe valves are used where throttling is required.
They are also used where both throttling and shut-off required.
Globe valves can also be used for on-off service.
They are mostly confined to those applications where the valve is normally closed and drop is not important when the valve is open.
They are also commonly used in those situations where minimum pressure drop and bidirectional on-off service is required.
Globe valves are used as sampling valves, which are normally shut except when liquid samples are being taken.

The gate valve is considered to be the most popular style of valve in the world of flow control. It is a type of valve having a gate that moves perpendicular to flow of the service and hence the name. A gate valve is usually used as a shut-off valve. In the up position, the valve is open. In the down position, the valve is closed. It is also known by other names like knife valve or slide valve or stop or block valve as its primary purpose is to stop the flow. This valve has become an important piece of fluid control equipment for more than 150 years. In fact, this was the first valve patent issued in the United States. The gate valve has become a one-stop solution for fluid control call with relatively little basic design change.

Check Valve a popular type of pipe valve are used to prevent flow reversal in piping systems. Check valves are appropriate for service in horizontal or vertical piping tuns. In other words, check valve is a mechanical device that allows fluid to flow through it in only one direction. Check valves consist of two-port valves. This means that they have two openings in the body, one for fluid to enter and the other for fluid to leave. That is why they are classified as “one-directional valves”. They are available in various designs, sizes and materials and used in a wide variety of applications.

Materials used:
Brass
Copper
Cast Iron
Bronze Ductile iron
Stainless steel
Metal alloys
Plastic
Ceramic etc.

Uses of check valve:
Check valves are best suited for moderate velocity applications.
They are often part of common household items.
They work automatically.
They do not have any valve handle or stem.
They are self-activating safety valves.
They permit gases and liquids to flow in only one direction.
They prevent liquid flow from reversing.
They are used in many fluid systems like in chemical and power plants, and in many other industrial processes.
They are capable of mixing multiple gases into one gas stream.
Check valves are installed in irrigation sprinklers and drip irrigation emitters to keep the lines from draining when the system is shut off.

Working of a check valve:
There is a hinged ball or door which is placed inside the valve. With the pressure coming upstream the ball is held open. On the other hand, when the pressure increases on the downstream side, it forces the ball or door to close which stops any back flow. An important factor in check valves is the cracking pressure. This is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed in such a way to specify a specific cracking pressure.

A butterfly valve is a rotary motion valve. The main purpose of butterfly valve is used to stop, regulate, and start fluid flow. This type of valve is easily and quickly operated because there is a 90 degree rotation of the handle which moves the disk from a fully closed to fully opened position. Butterfly valves are available in various sizes and materials. Infact, the larger sized butterfly valves are actuated by hand wheels which are connected to the stem through gears and they provide mechanical advantage at the expense of speed.

Parts of a butterfly valve:
The butterfly valve consists of only five main components. They are as follows:
Body: These valves have bodies that fit between two pipe flanges.
Disc: The disk is the flow closure member of a butterfly valve.
Stem: The stem of the butterfly valve is either a one-piece shaft or a two-piece, also known as split-stem design.
Seat: The seat of a butterfly valve utilizes an interference fit between the disk edge and the seat to close or to shutoff.

Type of Valves:
A valve is a piping components complete with operating system, able to control or shut off a fluid flow Valves are divided in:

A ball valve is a type of pipe vale that opens by turning a handle attached to a ball inside the valve. They are used for quick shut off and low emission application. They are durable and can work to achieve perfect shutoff or closure even after years of not-in- use. They are always an excellent choice for shutoff applications. They are sometimes preferred to globe valves and gate valves for this purpose. Although, ball valves cannot offer the fine control that may be required in throttling applications but are still sometimes used for this purpose.

Types of ball valves:
There are three general types of ball valves:
Full port: This has an over sized ball so that the hole in the ball is of the same size as the pipeline thereby resulting in lower friction loss. The valve is larger and the flow is unrestricted.
Standard port: This has a smaller ball and hence a smaller port. This is less expensive. Flow through this type of butterfly valve is one pipe size smaller than the valve's pipe size which results in slightly restricted flow.
Reduced port: Here the flow through the valve is two pipe sizes smaller than the valve's pipe size which also results in restricted flow.

Manifold Valves:
Manifold valves are widely used in the industrial fittings to reduce the cost of installation and prevent potential leakage. They help to simplify piping, improve the appearance and reduce the space requirements. These valves can further be customized according to a preferred connection type such as sockets, threaded, flare or o-ring face etc and are available in different configurations and styles for a wide range of process control applications. The device helps to control flow, pressure, level, distribution and blow down of water. Valve Manifolds are also available in either a block, single flange or double flange connection for remote or direct installation.

Blowdown Valves:
The blowdown valves are a very popular category of pipe valves, used in a wide variety of applications. They are used for operation in open position. The main function of blowdown valve is mainly to control a continuous flow of steam /fluid under high differential pressure. The outstanding feature of this type of valve is that it can maintain fluid tightness and it is easily operated without the help of any wedging action.
Uses of blowdown valves:
Certain uses of these valves are as follows:
These valves are appropriate for use with air compressors.
They are used to help in the removal of slug and unwanted materials after cleaning the pipes.
Blow down valves are found on the water feeders.
They are also used to lower water cut-offs.
They can control the concentration of solids in the boiler.
