It consists of upper and lower carbon steel, cast iron valve body, rubber sleeve, large and small valve stem gate, upper and lower guide column and other parts.
It is mainly used for centrifugal pump, mixed flow pump and axial flow pump outlet pipelines in automatic water supply and drainage pumping stations. It is designed with two kinds of control devices, namely piston type and diaphragm type, which can be used for clean water, raw water medium and sewage and slurry water medium respectively.
Through the auxiliary parts, the on-line operation of the valve can be fed back in real time, so as to realize the functions of automatic control and remote detection for distance transportation engineering.
In terms of product types, the company has developed four specifications, such as ordinary type, regulating type, sewage type and backwater low pressure type, to meet the needs of different customers in different working conditions.

Because of compact structure, small size and light weight, it is especially suitable for large diameter pipeline system.
It can be widely used in power, environmental protection, metallurgy, petrochemical, water department, municipal, food and other industries supply, drainage system, sewage pump house, chemical fluid transmission system, etc. It is the most novel structure at home and abroad, the most advanced performance, the most reliable operation of the pump station new control equipment.
