API 607 ball valves are specialized ball valves designed for fire protection, typically made from special materials such as cast iron, stainless steel, etc. They feature high-temperature resistance, fire resistance, and reliable sealing. Fireproof ball valves are suitable for fire protection in high-rise buildings, underground passages, power facilities, and other locations.
Differences between fireproof ball valves and ordinary ball valves:
Different structures
There are significant differences in structural principles between fireproof ball valves and ordinary ball valves. Fireproof ball valves use special materials for components like the ball, valve seat, and sealing rings, enabling them to maintain stable performance in high-temperature environments and avoid valve failure due to excessive heat.
Different safety performance
Compared to ordinary ball valves, fireproof ball valves offer higher safety guarantees. When closed, they can block the fire, prevent its spread, and ensure air circulation in surrounding areas to prevent smoke accumulation. In contrast, ordinary ball valves may have poor sealing during fires, potentially causing fire spread and increasing safety hazards.
Different purposes
Fireproof ball valves are mainly used for fire protection in high-rise buildings, underground passages, power facilities, and other locations as important fire protection equipment. Ordinary ball valves are more suitable for general fluid control systems, such as regional water supply, industrial production, and civil facilities.
