Our Pilot Operated Safety Relief Valve is a revolutionary structural safety valve, ideal for a wide range of industries including petroleum and natural gas, chemical industry, electricity, metallurgy, and urban gas. It stands as the ultimate overpressure protection device for pressure equipment, containers, or pipelines. This valve boasts numerous advantages: it shifts from direct spring action to the indirect action of the guide valve, enhancing the sensitivity. The main valve uses a sleeve piston type, ensuring high action accuracy, exceptional repeatability, elevated reseating pressure, superior sealing performance, and the capability to discharge with high back pressure. It offers stable and reliable operation, online adjustability, and ease of operation and maintenance.
Our comprehensive after-sales service includes routine valve maintenance and training for troubleshooting common issues. We offer remote or on-site valve assessments, installation, and operational technical guidance. Queries related to technical quality are responded to within 24 hours. We provide an 18-month product warranty (in line with national standards), 24-hour technical support hotline, and various forms of free after-sales service during this period. Lifetime after-sales service and limited free supply of wearing parts for the first 18 months are also available.
Q1: What is a safety valve?
1. Safety valves are essential for protecting life, property, and the environment. They are designed to open and release overpressure in a container or device, then re-close to prevent further fluid release once normal conditions are restored.
2. Safety valves serve as the final line of defense in many scenarios. It is crucial that they function reliably under all circumstances. Safety valves are neither process valves nor pressure regulators and should only be used for overpressure protection.
Q2: How does a safety valve work?
The working principle of a safety valve is detailed below:
1. Open: When system pressure exceeds the safety valve's set pressure, the valve disc opens under the pressure and spring force, releasing the excess pressure.
2. Keep Open: Once the system pressure stabilizes within the set limits, the spring maintains stability, keeping the safety valve open under system stress.
3. Close: When the system pressure drops below the safety valve's set pressure, the spring fails to lock and seal, causing the valve disc to close under medium pressure, thereby preventing further pressure increase.
