Product Description

Expertly engineered, this Full Lift Open Gas Valve features dual safety valves of identical model and specification, seamlessly integrated on a Y-shaped joint. The nominal diameter precisely corresponds to the Y-shaped joint's inlet diameter, ensuring flawless performance.
Perfectly tailored for applications involving steam, air, and various media with operating temperatures up to ≤ 350°C, this valve guarantees optimal safety. Upon detecting excess pressure within equipment or pipelines, it automatically opens to discharge fully, promptly reducing pressure to safe levels before closing-ensuring uninterrupted, secure operation.

FAQ

 

Q1: What is a safety valve?
1. The quintessential purpose of safety valves is to safeguard lives, property, and the environment. These valves are meticulously designed to open and release overpressure in any system, and to reclose once normal conditions are restored-ensuring no further fluid release.
2. Serving as a vital safety device, often the last line of defense, safety valves must remain reliable under all conditions. They are not to be confused with process valves or pressure regulators and should only function for overpressure protection.

Q2: How does a Safety Valve work?
The operational essence of a safety valve is as follows:
1. Open: When system pressure surpasses the safety valve's set threshold, the valve disc actuates, driven by medium pressure and spring force, to release the excess pressure.
2. Keep Open: As the system pressure stabilizes within the predetermined range, the spring maintains balance, allowing the valve to remain open under continued stress.
3. Close: When system pressure falls below the set threshold, the diminished spring force and medium pressure prompt the valve disc to close, halting any further pressure increase.
