● The valve body, made from high-quality materials, includes a ball test fitting and has its middle flane and neck bolted together.
● The valve seat has a single-piston effect for both upstream and downstream flow and features a Double Block and Bleed (DBB) function.
● Between the valve seat and the ball, there are three types of seals: a traditional soft seal, a triangular ring seal, and a hard seal.
● The valve stem includes safety features to prevent it from being ejected if operated improperly.
● The valve is equipped with devices to enhance fire safety and prevent static buildup.
● Emergency sealant injection ports are available for the valve seat seal and stem seal. These are used for repairs in case of leakage, and each port has a grease valve and a check valve.
● The valve has both drainage and venting ports. The drain valve is at the bottom for emptying and venting the cavity, and the vent valve is at the top for cleaning.
● This valve is compatible with various types of actuators, including manual, electric, and hydraulic.
● Valves with welded ends can have their materials adjusted to match the pipeline, ensuring proper welding. Sleeve extensions prevent interference with sealing during welding.
● Underground valves have extended stems to make above-ground operation possible, with accessible grease, drainage, and venting facilities. The stem height is customizable.

Triple Eccentric Metal Seated Butterfly Valve is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
The CH700 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
