Safety Valves

Safety valves are a high-technology valve product in which technical performance and safety are the highest priorities. Therefore, selecting a safety valve for a system should be carefully considered, and the product should come from reputable manufacturers with extensive manufacturing experience and reliable quality management systems. Safety valves are available for water, steam, and gas applications. Water safety valves are commonly available in threaded brass and flanged cast iron versions. There are direct-acting safety valves and pilot-operated safety valves. Pilot-operated safety valves are typically used on large-diameter flanged pipelines in HVAC, water supply, drainage, and fire protection systems. In particular, fire protection systems operate under high pressure and require high-capacity safety valves. Safety valves are recommended to be installed in multiple zones and branches to ensure maximum protection for the entire system. In steam systems, steam safety valves are extremely important. They relieve excess steam pressure when an overpressure condition occurs, helping prevent boiler explosions, steam pipeline rupture or leakage, thereby avoiding damage to property and protecting human life. Therefore, selecting a safety valve has never been a simple task and should never be underestimated. It must always be given top priority to ensure the selection of high-quality, reliable, and reputable safety valves.
