BZ943HF insulation electric flat gate valve

product description:

High-temperature and high-pressure power station gate valves are also called special valves for power stations. They are mainly used in the pipelines of various systems in thermal power stations to cut off or connect pipeline media. 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, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the special performance, technical characteristics and working conditions, the product has also formed the characteristics that other products cannot replace. Generally, such valves should be installed horizontally in the pipeline.

Structural features:

1. Adopt pressure self-tightening seal, and both ends of the valve body branch pipe are welded connection.

2. The valve seat and valve disc sealing surface are made of cobalt-based cemented carbide plasma spray welding, which has good wear resistance and scratch resistance.

3. The valve stem is treated with corrosion-resistant nitriding, which has good corrosion resistance and scratch resistance.
