The A48Y-type safety valve is meticulously engineered for equipment or pipelines handling steam, air, and other media with operational temperatures up to 350°C. Serving as an indispensable overpressure protection device, this valve automatically opens to release the entire amount when the internal pressure surpasses the permissible limit, safeguarding your system. Once the pressure drops to a designated safe level, the valve seamlessly closes, ensuring the continued safety and efficiency of your equipment and pipelines.
Our company offers comprehensive valve maintenance services along with expert training for troubleshooting common faults. We provide both remote and on-site valve assessments, installation assistance, and operational technical guidance. We commit to responding to technical quality inquiries within 24 hours. Additionally, we offer an extensive 18-month product warranty (in line with national standards), a 24-hour technical support hotline, and a variety of free after-sales services throughout the warranty period. Beyond the warranty, we extend lifetime after-sales support and a limited supply of free wear parts for 18 months.
Q1: What is a safety valve?
1. The primary function of safety valves is to protect life, property, and the environment. Designed to open and release excess pressure in a container or device, these valves automatically re-close to halt fluid release once normal conditions are restored, ensuring continued safety.
2. As vital safety devices, safety valves serve as the ultimate line of defense in many scenarios. It is crucial to ensure their functionality at all times and under all conditions. Safety valves are not intended for use as process valves or pressure regulators; their sole purpose is to provide overpressure protection.
Q2: How does a Safety Valve work?
The operational principle of a safety valve is as follows:
1. Opening: When system pressure exceeds the safety valve's set threshold, the valve disc opens due to medium pressure and spring force, releasing the excess pressure.
2. Remaining Open: As system pressure stabilizes within the set threshold, the spring maintains stability, keeping the system under control and the safety valve open.
3. Closing: When system pressure falls below the safety valve's set threshold, the spring can no longer lock the valve disc, which then closes under the influence of medium pressure, preventing further pressure increase.
