Product Description
Product Description

Pilot operated safety relief valve is a novel structural safety valve. Mainly used in fields such as petroleum and natural gas, chemical industry, electricity, metallurgy, and urban gas, it is the best overpressure protection device on pressure equipment, containers, or pipelines. Its main advantages are that the direct action of the spring is changed to the indirect action of the guide valve, which improves the sensitivity of the action. The main valve adopts a sleeve piston type, which has high action accuracy, good repeatability, high reseating pressure, good sealing performance, can discharge with high back pressure, stable and reliable work, can be adjusted online, and is easy to operate and maintain.

Application Scope

FAQ

Q1:what is the safety valve ?
1. The main purpose of safety valves is to protect life, property and the environment. A safety valve is designed to open and release overpressure in a container or device, and to re-close and prevent further fluid release when it returns to its normal state.
2. A safety valve is a safety device that is in many cases the last line of defense. It is important to ensure that the safety valve can operate at all times and under all circumstances. Safety valves are not process valves or pressure regulators and should not be abused. It should be run for one purpose only: overvoltage protection.

Q2:How does a Safety Valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When the system pressure exceeds the set pressure of the safety valve, the valve disc opens under the action of medium pressure and spring force, releasing pressure.
2.Keep open: When the system pressure stabilizes within the set pressure, the spring stabilizes, the system remains under stress, and the safety valve remains open.
3. Close: When the system pressure is lower than the set pressure of the safety valve, the spring cannot lock and seal, and the valve disc closes under the action of medium pressure, and the medium pressure no longer increases.
