Structural Features

Carbon Steel Material: Key pressure-retaining components such as the valve body and bonnet are made of high-quality carbon steel (e.g., WCB, WCC), featuring high strength, excellent toughness and moderate corrosion resistance. They can withstand high pressure and temperature, ensuring the valve's structural integrity and long-term stable operation under severe working conditions.
 Flanged Connection: Standard flanged connections are adopted (with sealing face types including RF, RTJ, etc.), complying with international standards such as ASME B16.5 or ASME B16.47. They feature easy installation, reliable sealing, convenient integration with existing piping systems, as well as easy later maintenance and overhaul.
 Handwheel Actuator: Equipped with a high-quality handwheel actuator that is lightweight and flexible to operate, enabling precise opening and closing control of the valve. The handwheel is ergonomically designed with moderate operating torque, allowing on-site personnel to perform switching operations quickly and accurately. Position indicators and locking devices can also be provided to prevent misoperation.

Applications

Oil & Gas Industry: Used in oil and gas field exploitation, gathering and transportation pipelines, long-distance pipelines, refineries, petrochemical plants, etc., to provide reliable shut-off and isolation for crude oil, refined products, natural gas and other media.
Chemical Industry: Suitable for process pipelines in various chemical plants, controlling the flow of diverse chemical media to ensure production safety and process stability.
Power Industry: Applied in steam systems, feedwater systems, cooling water systems, etc. of thermal power plants and nuclear power plants to guarantee the safe operation of key systems.
Metallurgical Industry: Used for pipeline control of blast furnace gas, converter gas, oxygen, nitrogen and other media in iron and steel plants.
Water Treatment Industry: Used for pipeline shut-off in municipal water supply, wastewater treatment, seawater desalination and other systems.
Other Industrial Fields: General industrial applications in papermaking, pharmaceuticals, food and beverage, shipbuilding and other industries.
