China's achievements in casting industrial parts are among the best in the world, and naturally the level in the field of ball valve production is the same.

WZLD ball valve is based on API 6D standard, and our unique manufacturing process in China is added to the design of the ball valve. In terms of sealing, the method of metal plus graphite composite valve seat can make the ball valve have the rigid support of metal ring at high temperature, and with flexible graphite filling, it can achieve two-way zero leakage in the actual operation process, reaching the highest standard level of API sealing.

In terms of fire prevention, the design material of WZLD ball valve is very unique. The special material graphite is developed, which can expand rapidly when encountering fire, directly isolate the fire source, and solve the hidden danger of fire. In addition to fire prevention, anti-static and anti-explosion designs are also added. Zirconium alloy spring conductive devices are embedded between the ball and the valve stem, and the static resistance is less than ten, eliminating the risk of flammable gas explosion.

Forged steel ball valves are mainly used in critical industrial occasions with extremely strict requirements on safety and reliability due to their excellent high-pressure tolerance, excellent high-temperature stability and excellent sealing performance. In the field of oil and gas industry, it is widely used in oil and gas field exploitation, long-distance pipeline main pipelines, and high-pressure devices in refineries to accurately control the flow of flammable and explosive media. In the power industry, especially in the core positions of high-temperature and high-pressure steam systems and water supply pipelines in thermal power and nuclear power projects, forged steel ball valves are indispensable key opening and closing components. At the same time, in various types of high-pressure, highly corrosive or harsh process pipelines with special requirements for cleanliness in the petrochemical, chemical and pharmaceutical industries, this type of valve is also favored due to its sturdy valve body structure. It plays an important role in withstanding extreme working conditions and ensuring the safety of key processes.
