Product Description

This state-of-the-art valve features two identical safety valves mounted on a Y-shaped joint. The nominal diameter specifically refers to the inlet diameter of this Y-shaped joint, ensuring precision and reliability.
Engineered for steam, air, and various media with working temperatures up to ≤ 350°C, this valve automatically activates when internal pressure surpasses the safe threshold, discharging fully to maintain balance. Once the pressure returns to the acceptable range, the valve securely closes, safeguarding your equipment for optimal operation.

FAQ

 

Q1: What is a safety valve?
1. Safety valves are crucial for protecting lives, property, and the environment. These valves are designed to release excess pressure from containers or devices and re-seal once normal conditions are restored, preventing further fluid release.
2. Often serving as the final safety measure, these valves must function reliably under all circumstances. Safety valves are distinct from process valves or pressure regulators and should solely be used for overpressure protection.

Q2: How does a safety valve work?
The working principle of a safety valve is straightforward:
1. Open: When system pressure exceeds the safety valve's set point, the valve disc responds to medium pressure and spring force, opening to release excess pressure.
2. Keep Open: The safety valve remains open as long as the system pressure stabilizes within the set range, maintaining stress equilibrium through spring balance.
3. Close: When the system pressure drops below the set point, the spring loses its force, allowing the valve disc to close under medium pressure, ensuring no further pressure buildup.
