This article describes the importance of the three core items of safety valve testing: opening pressure, flow characteristics and gas (water) tightness. The opening pressure determines when the safety valve opens, the flow characteristics affect the pressure relief efficiency, and the airtightness test ensures daily reliability. Precision Engineering provides multi-channel test equipment to realize the leap from experimental verification to mass production quality inspection, and its testing program forms a complete logical closed loop, applicable to new energy, energy storage systems and other demanding fields.
