What Are The Precautions For Installing Instrument Valves?

There are several precautions to follow when installing instrument valves. First, confirm the installation direction. Some instrument valves (such as check valves and throttle valves) have specific flow direction requirements and must be installed according to the arrow on the valve body to avoid affecting functionality due to reverse installation. Second, ensure the installation environment is clean, with no impurities or welding slag in the pipeline to prevent valve core blockage or wear. Pay attention to sealing during installation; flange connections must have bolts tightened evenly to avoid media leakage due to poor sealing. Furthermore, allow sufficient space for operation and maintenance; manual valves must ensure smooth handwheel rotation, and automatic valves must be easily accessible for actuator maintenance. Consider the characteristics of the medium; if the medium contains impurities, a filter can be installed before the valve. After installation, a pressure test must be performed to check the valve's sealing performance and operational flexibility, ensuring the installation is qualified before putting it into use.
