Whenever a valve is to be installed, be sure to know the function the valve is going to perform, that is whether it will start flow, regulate flow, stop flow, prevent back flow, or regulate pressure. The valve body must be inserted according to the information that is stamped upon it by the manufacturer-like type of system (gas, oil, and water), direction of flow, operating pressure etc.
?It is wise to apply the basics of proper valve maintenance, in order to improve fluid flow and operating efficiency. There are 5 basic valve maintenance steps:
?·???????Understanding Valve Markings and Components: Valves are identified by markings inscribed on the body, rims of the hand wheel, or to the adjacent piping.
?·???????Valve Connection: Proper valve connection procedures should be taken into due consideration during installation on piping systems. In other words, the pipe should be properly aligned before the installation of a valve.

?·???????Ensure Valve is clean before installation: In good process operations, prior to installation, valves must be free from all dirt, and foreign matter. In some cases, the valve and the line should be blown out with clean instrument air, steam, or clean water.
?·???????Proper Valve Storage: Valves should be kept in a safe place, away from weather, dirt etc. Valves must be in protective covers and kept in place until the time of installation.
?·???????Valve Inspection upon Receipt: Whenever a valve is received, thorough inspection should be carried out on it, because this is always the critical time in Upon receipt, the valves must be inspected for in-transit damage. And inspection should be focused on the valve actuator, valve stem, and valve ends etc.
?In summary, it is imperative that valves and their respective pipe connections are properly aligned at initial installation. When in doubt, always refer to the valve manufacturer for proper use and installation. In addition, for adequate fluid flow control, team work between the unit operator and panel operator is essential.
