● 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.

Stop Check Valve, A multi-purpose valve that functions as both a stop valve and a check valve. Its structure is similar to that of a globe valve, but the stem and disc are not fixed. When the stem is lowered and the disc is pressed tightly on the seat, it acts as a stop valve; After the stem rises, the check valve acts. On lines that require both a stop valve (or gate valve) and a check valve (such as the outlet of a water pump), using a stop check valve can save installation costs and space. In the opening and closing process, because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, it is more wear-resistant.
The Forged Steel Compact Globe Valve is a high-performance fluid control device, precision-engineered from premium forged steel material. It combines throttling and shut-off functions in one unit. Designed specifically for high-pressure and high-temperature applications, it features compact construction, reliable sealing, and extended service life, making it ideal for demanding conditions in petroleum, chemical, power, and other industries.
The API 6A High Pressure Slab Gate Valve is specially designed for high-pressure pipeline systems in industries such as petroleum, natural gas, and chemical engineering. It features a valve body made of high-quality alloy steel, which is precisely machined and rigorously tested to ensure reliable performance under high pressure, high temperature, and corrosive medium conditions. The unique flat gate plate design enables two-way sealing, allowing for flexible opening and closing with low flow resistance. It is an ideal choice for long-distance pipelines, refining and chemical plants, and high-pressure fluid control systems.
