Product Details

product description:


With pressure self-tightening sealing structure, the two ends of the branch pipes are welded and the sealing surface is sprayed with cemented carbide powder, which has the advantages of being changed to wear resistance and not easy to scratch. The surface of the valve stem is anti-corrosive and nitrided, and has good corrosion resistance Scratch resistance


Structural features:


1. The forged valve has good stability and high comprehensive mechanical properties.


2. The toughness is very good, can withstand normal work under high pressure environment, the pressure rating of casting valve is generally relatively low.


3. The structure of forged valves is generally simple, making it easy to manufacture and maintain.


4. The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium.


5. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure.


6. Simple shape, short structure length, good manufacturing technology and wide application range.


7. The material mouth is fully circulated without any obstructions, and there is a blowing and blocking device, and there is less dust jam and accumulation;
