China Large DN Size Oxygen Special Valve Manufacturer, Supplier, Factory

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®️ Electric actuated cast steel ball valve as a high-performance product that meets international standards like API-6A, API-6D, ASME-B16.34, ISO-17292 and more. Hero®️ Electric actuated cast steel ball valve has obtained API-6FA fire certification, which prove product has capacity to use for various fire safe requested applications. Hero®️ as a manufacturer to produce Electric actuated cast steel ball valve can manufacturing NPS 2” to NPS 48” Electric actuated cast steel ball valve, maximum pressure rating can reach to 2500LB. Furthermore, Hero®️ has conditions and experience to produce low-temperature Electric actuated cast steel ball valve. Contact our sales for more information.

As a type of Check valve, the 1500LB swing check valve uses the swing disk as the sealing structure. , and uses carbon steel as body material. Hero®️ 1500LB swing check valve can meet standards such as API, DIN.

Hero®️ Gas over oil actuated 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.

Hero®️ 1500LB Globe valve can meet standards such as API, DIN, ISO, GOST, GB, JIS. Produce size range from NPS10 inch up to 10 inch , DN250 to DN250. Pressure rating covers ANSI Class1500LB and PN250.

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.
