FAQ

Q1: What is a safety valve?
1. The primary purpose of safety valves is to safeguard life, property, and the environment. A safety valve is designed to open and release excess pressure in a container or device, re-closing to prevent further fluid release once the system returns to a normal state.
2. A safety valve serves as a critical safety device, often being the last line of defense. It is imperative to ensure that it can operate reliably under all conditions. Safety valves are not to be mistaken for process valves or pressure regulators and must be used exclusively for overpressure protection.

Q2: How does a Safety Valve work?
The operation of a safety valve can be summarized as follows:
1. Opening: When the system pressure exceeds the safety valve's set pressure, the valve disc is pushed open by the medium pressure and spring force, allowing excess pressure to be released.
2. Maintaining Open: Once the system pressure stabilizes within the set pressure range, the spring balances, keeping the valve open while the system remains under controlled stress.
3. Closing: When the system pressure drops below the set pressure, the spring force prevails, causing the valve disc to close under the medium pressure, thereby stopping further pressure increase.
