A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball also called as a “floating ball” to control flow through it. It is opened when the hole of ball is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when opened and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status.

 

Butterfly valve, also called as flap valve is a valve that has simple structure, used for media having low pressure. The closure member of butterfly valve is a disc which can swing along with valve shaft. Operation is similar to that of a ball valve, which allows for quick shut off. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. There are different kinds of butterfly valves, adapted for different pressures and different usage.

 

Check valve, also called as clack valve, non-return valve or one-way valve is a valve normally allows media (liquid or gas) to flow through it in only one direction. Check valve is two-port valve, which means that there are two openings in the body of check valve, one for media to enter and the other for media to leave. There are various types of check valve used in a wide variety of applications. Accordingly, most of check valves do not have any valve handle or stem. Plastic or metal can be used for bodies (external shells) of the check valve. Typically, check valve is designed for and can therefore be specified for a specific cracking pressure.

 

Diaphragm valves offer many combinations of body materials and elastomeric diaphragm materials. The diaphragm valve design is abrasion-resistant and non-clogging. When the diaphragm, which is connected to the stem of the valve by a compressor, is pulled away from the bottom of the valve body, the path of the fluid has a smooth, streamlined flow.

 

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.
