China Reduced Trunnion Bore Ball Valve Manufacturer, Supplier, Factory

Hero®️ cast steel trunnion mounted ball valve as a high-performance product that meets international standards like API-6A, API-6D, ASME-B16.34, ISO-17292 and more. Hero®️ cast steel trunnion mounted ball valve has obtained API-6FA fire certification, which prove product has capacity to use for various fire safe requested applications.

Hero®️ Gas-over-oil full welded ball valve through a self-actuating actuator. By the pressure of the medium of the pipeline itself to actuate valve open and close. The product directly use natural gas inside of the pipeline as the air supply of pneumatic. The whole system design for high pressure. Through air supply filtering process without decompression. The gas directly into the gas tank and high-pressure control valve components. Under the action of the control signal, the high-pressure controlled gas enters the corresponding gas/liquid circuit. And by the principle of isobaric transmission of the liquid medium to realize the gas/liquid synchronous transmission, acting on the hydraulic cylinder of the valve drive device and controlling the valve.

Hero® gate valves are designed to be high performance. We invest heavily in refining our manufacturing processes and implementing stringent quality control measures to ensure that our high pressure gate valves stand out for their superior quality and durability in comparison to their counterparts.

Hero®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.

Hero® Reduced Bore Ball Valve is designed to provide superior quality and performance. Our engineering team implements strict quality control measures to ensure that our ball valves offer durability and quality that surpasses competing products. We use advanced manufacturing processes and stringent quality control measures to ensure that every valve meets the international standards.

As a type of Ball valve, the DBB double block and bleed ball valve uses the Trunnion mounted as the sealing structure. The valve actuated by Worm gear, and uses carbon steel as body material.
