A manual actuation lever for testing pressure relief valve functionality in industrial metal tank systems.
The Test Lever is a critical safety component in Metal Tank Pressure Relief Valve Assemblies, designed to manually actuate the valve mechanism for periodic functional testing without requiring system pressurization. This lever provides a mechanical advantage to overcome spring tension and verify proper valve disc movement, ensuring the relief valve will operate correctly during overpressure events. It typically connects to the valve stem or actuator through a pivot point and linkage system.
