Manual Butt Welded Gate Valve

Product Description

The gate valve adopts the manual butt welded connection form, the open rod wedge type rigid single gate plate, the valve seat sealing surface material is cemented carbide, the nominal pressure is PN250~PN320, and the valve body material is carbon steel high temperature and high pressure power station gate valve.

Features

1. Open and close without friction. This function completely solves the problem that the conventional valve affects the sealing surface due to friction between the sealing faces.

2. The top-loading structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the parking of the device.

3. Single seat valve design. It eliminates the problem that the cavity medium in the valve affects the safety of use due to abnormal boosting.

4. Wedge seal structure. The valve is mechanically supported by the valve stem, and the wedge is pressed against the valve seat to seal, so that the sealing performance of the valve is not affected by the pressure difference of the pipeline, and the sealing performance is guaranteed under various working conditions.

Application

The high temperature gate valve is also called the special valve for the power station, and is mainly used for the pipelines of various systems of the thermal power station, cutting or connecting the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, power station valves are characterized by high temperature and high pressure and unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the technical characteristics of the performance, the special conditions of the working conditions make the product also have the characteristics that other products can not replace.
