UAE Valves is a reputed Safety Valve supplier in Dubai. A safety valve protects systems from overpressurization. Overpressure occurs when the system’s pressure exceeds the maximum allowable operating pressure. Safety valves open at a predetermined pressure: initially, they open partially, then fully, to quickly release the excess pressure. Safety valves prevent pressure build-up that could lead to malfunctions, explosions, or fire risks. During a power outage, the system’s medium fully activates the safety valve, ensuring its operation. Safety valves consist solely of mechanical components, which function even if pneumatic or electrical safety systems fail.
The spring pressure of a safety valve is adjusted by pulling a lever positioned over the valve. An internal spring is inserted into the valve, with one end attached to the lever and the other to the valve body. The spring force helps to keep the valve on its seat.
Working Principle of a Safety Valve:
A spring or mechanical force holds the valve disc or plug firmly against the valve seat when the safety valve is closed. When the system pressure exceeds a predetermined set point and surpasses the spring force, the valve is forced upward and off the seat, creating an opening to release excess pressure. The pressurized gas or fluid flows through the safety valve and exits to a safe location, like an exhaust pipe or a specified outlet. When the pressure drops below the set point, the spring or mechanical force pushes the valve disc down, causing the valve to close and re-seat, stopping further release of fluid or gas. The safety valve acts as a fail-safe mechanism, ensuring pressure is released when it exceeds a set point, thus protecting systems and equipment from damage or failure. Routine testing and maintenance are necessary to ensure the safety valve’s proper performance and reliability. Safety valves are a critical safety measure in various industrial applications due to their repeatable and dependable construction.
