Shut Off Valves
A shut off valve is a type of safety valve that stops the flow of materials like air, gas or water in a pipeline. The stopping of the flow is made possible by the various parts of this stop valve. There are different parts for a safety valve. Despite the differences in the types most of these valves have the same basic parts that serve the purpose of stopping the flow of materials within a pipeline. Here are the parts and here are some ways to know how to differentiate each part.
There are two basic parts for a shut off valve namely the control mechanism and the stopping mechanism. The control mechanism is responsible for regulating the flow of materials such as liquid or air within the pipeline. The stopping mechanism is the part which is responsible for preventing the flow of material within the pipeline system. These two parts vary depending on the type and the purpose of the safety valve. These parts are also subject to the usual wear and tear that comes with the use of this valve and knowing these parts could help in prolonging the life of a valve.
