Study of Packing Material used in Control Valve for Fire Fighting Installation

It is beyond imagination that any matter supply is being processed without medium like pipeline of different material and nature so to controlling by means of different king of valve to regulate same. Valves are the most common single piece of equipments found in any utility and services although there are many types, shapes and sizes of valves, they all have the same basic parts. This paper will review the common parts of control valve as packing and sealing so as the functions. The traditional control valve selection process includes selecting a valve design based on (1) Pressure (2) Temperature capability (3) Flow characteristics (4) Characteristics of fluid (5) Material compatibility and other factors. One such major factor is packing selection, which has gained significant attention over the years due to stringent environmental and safety concerns. Today every industry is concern and wants the lower maintenance and higher life performance of packing and sealing materials to minimise the loss and, breakdown and failure related. Packing’s and sealing being suitable not only for those applications where the control of fugitive emissions is a requirement, but also for non-environmental applications involving higher temperature and pressure like in petrochemical industries.
