Stainless steel pneumatic discharge valve

Stainless steel pneumatic discharge valve

The discharge valve is mainly used for bottom discharge of reactors, storage tanks, and other containers. With the help of the valve bottom flange welded to the bottom of the storage tank and other containers, it eliminates the residual phenomenon of process medium at the bottom of the container. The discharge valve is designed with a flat bottom according to the actual situation, and the valve body is V-shaped. It also provides valve discs with two working modes: lifting and lowering. The inner cavity of the valve body is equipped with a wear-resistant and corrosion-resistant sealing ring, which can protect the valve body from being washed and corroded by the medium when the valve is opened. The sealing ring is specially treated to achieve a surface hardness of HRC56-62, with high wear resistance and corrosion resistance.

Applicable medium temperature:

1. Use media such as water, acetone, alcohol, ammonia, barium carbonate, and benzene (the temperature for WCB material is -29 ℃ -425 ℃).

2. Use media such as particles, oil, pulp, and carbon dioxide gas (stainless steel material can be used at temperatures of -60 ℃ -232 ℃).

3. It is strictly prohibited to use fluorine-containing ionic liquids (such as HF), as well as strong bases and phosphoric acid (temperature less than 150 ℃, concentration>30%).

4. The general working temperature of stainless steel is ≤ 150 ℃, and the pressure range is 0.6-2.5MPA. If it exceeds this requirement, it should be explained when ordering.

Corrosion resistance:

1. Polytetrafluoroethylene has excellent adhesion to metals, moderate tensile strength, and resistance to dilute and concentrated acids.

2. Use media such as particles, oil, pulp, and carbon dioxide gas (stainless steel material can be used at temperatures of -60 ℃ -232 ℃).

3. It is strictly prohibited to use fluorine-containing ionic liquids (such as HF), as well as strong bases and phosphoric acid (temperature less than 150 ℃, concentration>30%).

4. The general working temperature of stainless steel is -5 ℃ -225 ℃, with a pressure range of 0.6-1.6MPA. Orders exceeding this requirement should be specified.
