Types of valve used in piping learn about 9 types of valves. Pipeline block valves should be used to limit the release of line contents in case of leaks or pipeline ruptures outside plant boundaries. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. Examples of the common types are the ball valve, butterfly valve, globe valve. These valves are similar to gate valves and use linear motion to throttle flow. September page 1 introduction to pipelines there are over 2. They are used to control the flow in a pipeline and they regulate by the position of a movable disk or plug in relation to the stationary ring seat. Learn about 9 different types of valves used in piping such as gate valve, globe valve, check valve, plug valve, ball valve, butterfly valve, needle valve, pinch valve and pressure relief valve. Typically used for cooling water systems, transporting fuel oil and turbine lube oil systems, a globe valve is a linear motion valve used to stop, start and regulate flow.
These valves are called sectionalising block valves. Conventionally used for isolation and throttling services, the globe has become the worlds most common types of valves. This type is the most used in piping and pipeline applications. Classification of valves used in piping learn 4 methods. Different types of valves used in piping mech4study. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. These valves are for api6d pipeline applications but are also used for. Sectionalizing valve sv are installed at regular intervals around 25 to 40 kms. Pipeline basics specithcs about natural gas pipelines pipeline briefing paper 2 last updated. Introduction to the types of valves because of the diversity of the types of systems, fluids, and environments in which valves must operate, a vast array of valve types have been developed. Learn about the classification of valves that are used in piping. Different types of valves with pdf file engineering. Even though the main purpose of valves is to control the fluid flow, they can be used to regulate the pressure, direction of flow within the piping system. Trap collar while joining two pipes in the same length, collar is used.
