Safety Valve
Safety valves are automatic pressure-relieving devices designed to protect equipment, systems, and personnel by releasing excess pressure when it exceeds a preset limit. They ensure safe operation in pressurized systems without the need for external power.
Overview
A safety valve is a critical protective component installed in pressurized systems to prevent overpressure conditions that could lead to equipment damage, explosions, or safety hazards. It operates automatically based on system pressure.
Operating Principle
When the inlet pressure reaches a predetermined set pressure, the valve disc opens automatically and discharges excess fluid such as steam or gas. Once the pressure drops to a safe level, the valve closes again, restoring normal operation.
