It is widely used in industrial control systems to adjust the direction, flow rate, speed and other parameters of the medium. In the context of solenoid valves and other fluid control equipment, pressure resistance is an important indicator to measure their performance and safety. As an automated basic component for controlling the flow of fluids (including gases, liquids, etc.), solenoid valves play a key role in many industrial applications. The pressure resistance test of solenoid valves is an important quality control process to ensure that the solenoid valves can work safely and reliably within their nominal pressure range. This process usually includes type testing and shipment inspection, which will test various performance indicators of the solenoid valve, such as sealing, pressure resistance, response time, etc.
