Characteristics

The valve control can be used for local and remote control, and can also realize remote position display and remote centralized control according to user requirements.

The structure is short and the weight is light: the body is made of carbon steel, and the weight is reduced by about 20%-30% compared with the traditional gate valve, and the installation and maintenance are convenient.

The use of the valve can improve the closing and sealing performance of the conveying pipeline system, and minimize the leakage, which will play an active role in promoting production efficiency and protecting the environment.

The sealing surface is made of high wear-resisting and corrosion-resistant ceramic material. It adopts inlay technology, high corrosion resistance and good wear resistance, which makes the valve have long service life and the cost performance is 10 times higher than that of ordinary valves.
