A48Y type safety valve is meticulously crafted for equipment or pipelines that handle steam, air, and other media with working temperatures up to 350°C. Serving as a paramount overpressure protection device, this valve automatically opens when the internal pressure exceeds the permissible limit, thereby discharging the entire pressure. Once the pressure descends to the specified safe level, the valve seamlessly closes, ensuring the utmost safety and integrity of your equipment and pipelines.
Our company offers comprehensive after-sales services, including routine valve maintenance and troubleshooting training for common faults. We provide both remote and on-site technical guidance for valve review, installation, and operation. Queries regarding technical quality are addressed within 24 hours. We offer an 18-month product warranty as per national standards, 24-hour technical support hotline, and various free after-sales services during the warranty period. Additionally, we offer lifetime after-sales service and limited free supply of wearing parts for 18 months.
Q1: What is a safety valve?
1. The primary function of safety valves is to safeguard life, property, and the environment. These valves are engineered to open and release excess pressure in a container or device and to re-close to prevent further fluid release once normal conditions are restored.
2. Acting as the final defense mechanism, a safety valve ensures operational integrity at all times and under all circumstances. Unlike process valves or pressure regulators, safety valves are solely designed for overpressure protection and should be used accordingly.
Q2: How does a safety valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When system pressure surpasses the set threshold, the valve disc is forced open by the medium pressure and spring force, thereby releasing the excess pressure.
2. Keep open: Once the system pressure stabilizes within the set range, the spring's stabilization allows the valve to remain open under sustained system stress.
3. Close: As system pressure falls below the set limit, the spring's inability to lock and seal causes the valve disc to close under the medium pressure, halting any further pressure increase.
