FAQ

Q1: What is a safety valve?
1. Safety valves are crucial for protecting life, property, and the environment.
A safety valve is engineered to open and release excess pressure from a container or device, then re-close to prevent further fluid release once normal conditions are restored.
2. Serving as a critical safety device, the safety valve often acts as the final line of defense.
It is vital that safety valves operate reliably at all times and under any circumstances.
Safety valves are distinct from process valves or pressure regulators and should be used solely for overpressure protection.
Their primary function is singular: to provide overpressure protection.
Q2: How does a safety valve work?
The working principle of a safety valve can be delineated as follows:
1. Open: When system pressure surpasses the valve's set pressure, the valve disc opens under the pressure from the medium and the spring force to release excess pressure.
2. Keep Open: Once system pressure stabilizes within the set range, the spring maintains equilibrium, ensuring the system remains under control and the valve stays open.
3. Close: When system pressure drops below the valve's set pressure, the spring cannot lock the valve, causing the valve disc to close under medium pressure, thus halting any further pressure increase.
