● Friction-Free Operation: The ball turns only after moving away from the seat, eliminating friction and reducing wear common in traditional ball, gate, and plug valves.
● Injectable Packing: Allows for online maintenance by injecting packing into the stem through a port, effectively controlling emissions. This feature is applicable to all models with a
sealed cover.
● Single Seat Design: The rising stem ball valve's single static seat ensures zero downstream leakage and avoids the pressure
build-up issues common with double-seated designs.
● Extended Service Life: This valve can replace other valves prone to sealing failures, such as standard ball valves, gate valves, and plug valves, reducing failure rates and maintenance costs significantly.
● Optimal Flow Characteristics: Both full-bore and reduced-bore valves maintain high Cv values when open, enhancing pump efficiency and minimizing corrosion issues.
● Top Entry Design: Facilitates inline inspection and maintenance after decompressing the pipeline system, simplifying upkeep.
● Dual Stem Guides: The stem moves smoothly up and down, and rotates along guide pins, ensuring stable control.
● Self-Cleaning Feature: When the core is off the seat, the medium flows 360 degrees along the sealing surface, washing away impurities.
● Low Torque Operation: The elimination of sealing friction makes the valve easy to turn, allowing the use of a small handwheel without the need for a gearbox, except in very large
sizes.
● Wear-Resistant Hard Sealed Surfaces: The core's sealing surfaces are overlayed with hard alloy and polished, maintaining seal
integrity even under harsh conditions.
● Mechanical Wedge Seal: The inclined surface at the bottom of the stem provides a mechanical wedge force, ensuring continuous
tight contact between the core and the seat.

Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
The Power Plant Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the Power Plant Gate Valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The Power Plant Gate Valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
