2W21 12V solenoid valve for low-pressure systems: zero leakage, low power, durable brass/SS body, no overheating. 1/2”-2”, 0-1.0MPa." (228 chars)

This article systematically analyzes the key role and technical characteristics of safety valves as core components of industrial safety. Safety valves ensure the safe operation of pressure vessels and systems by automatically releasing overpressure media (gas, liquid or steam). Their working principle is based on precise spring force or lever counterweight design. When the pressure exceeds the preset set pressure…
