Product Description

Product Description

The A42Y safety valve is engineered for use in equipment or pipelines handling gas, liquid, and other media at temperatures up to 300 ºC. Acting as a vital overpressure protection device, it automatically opens to release excess pressure when it surpasses the allowable threshold, ensuring full discharge. Once the pressure drops back to the specified value, the valve closes automatically to maintain the secure operation of your equipment and pipelines.

FAQ

Q1: What is a safety valve?
1. The primary purpose of safety valves is to safeguard life, property, and the environment. Designed to open and release overpressure in containers or devices, they re-close to stop further fluid release once normalized conditions are restored.
2. A safety valve acts as a crucial last line of defense. It's paramount that the safety valve functions flawlessly under all conditions. These valves are specifically for overpressure protection and should not be misused as process valves or pressure regulators.

Q2: How does a Safety Valve work?
The operating principle of a safety valve can be outlined as follows:
1. Open: When system pressure exceeds the valve’s set threshold, the valve disc opens under medium pressure and spring force, releasing the excess pressure.
2. Keep open: When the pressure stabilizes within the set limit, the valve remains open under spring stabilization, ensuring the system stays under manageable stress.
3. Close: If system pressure falls below the set limit, the spring cannot sustain the lock, and the valve disc closes, preventing further increase in medium pressure.
