Product Description


This valve is equipped with two safety valves of the same model and specification on a Y-shaped joint, and its nominal diameter refers to the inlet diameter of the Y-shaped joint.
This valve is suitable for steam, air, and other media with a working temperature of ≤ 350c on equipment or pipelines. When the pressure inside the equipment or pipeline exceeds the allowable value, the valve will automatically open and then discharge in full. When the pressure drops to the specified value, the valve will automatically close to ensure safe operation of the equipment.

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.
