Application Case – CF8M DN250 PN100 DBB Plug Valve In The Chemical System

ZZJG recently provided a batch of general valves for a large-scale chemical project. The product is made of CF8M material. The diameter of this Double Block & Bleed (DBB) Plug alve is DN250 (10 inches). The pressure rating of this valve is PN100 (Class 600). This product is used in harsh corrosive and high-pressure working conditions.

1. Project Background

This project employs orbit plug valves in a chemical plant. The plant handles highly corrosive media. The media includes acidic liquids and fluids containing chlorides. The operating conditions require the valves to have excellent performance. The valves need to be corrosion-resistant. They need to have reliable sealing. They also need to operate stably for an extended period.

2. Product Solution

For this project, ZZJG selected CF8M stainless steel general plug valves. This material has excellent corrosion resistance. It can withstand various chemical media. CF8M contains molybdenum. Therefore, its performance is similar to that of 316 stainless steel. This material is widely used in harsh environments. It can reduce pitting corrosion and crevice corrosion.

This valve is designed with a DN250 large-diameter. Therefore, this Dual Expanding Plug Valves can meet the requirements of high flow rate. The pressure rating of this valve is PN100. So this valve can operate safely under high pressure. The Twin Seal Orbit Plug valve is equipped with a gear operation device. This design makes the valve operate more smoothly. This design is also suitable for large-diameter working conditions.

3. Application Advantages

This General Twin Seal Valve has the following features:

* Excellent corrosion resistance.

Therefore, this valve can be used in acidic substances, seawater and highly corrosive media.

* Stable sealing performance. Thus, this valve can reduce leakage.

* Used in high-pressure systems. This valve is suitable for PN100 / Class 600.

* Sturdy structure. Therefore, this API DBB Orbit Plug Valve requires less maintenance. This valve lasts longer.

In a chemical plant, valves come into contact with many corrosive substances. These substances include sulfuric acid, hydrochloric acid, caustic soda, chlorides and organic solvents. These conditions usually involve high pressure. The temperature also varies. The equipment needs to operate for a long time. Therefore, these conditions place very high demands on the valves.

The CF8M stainless steel Twin Seal Orbit Plug Valve can handle these conditions. This valve can prevent pitting corrosion. It can also prevent crevice corrosion. The valve can also resist chemical corrosion. It is suitable for environments with high chloride content.

Twin Seal Orbit Plug Valve can be used in the following scenarios:

* Acid transportation systems, such as sulfuric acid, hydrochloric acid and nitric acid.

* Alkali systems, such as sodium hydroxide and potassium hydroxide.

* Chlorine and chlorine-containing medium systems.

* Solvent processing and storage systems.

* Isolating the inlet and outlet of reactors.

* High-pressure feeding and liquid injection systems.

This type of General Valve Orbit Plug Valve is widely used in the petroleum, natural gas and chemical industries. This valve can be used in pipeline systems. It can be used for isolation. It can also control the flow rate.

4. Customer Feedback

After the installation of the project was completed, the Orbit Plug Valve operated smoothly. The sealing performance of the valve was stable. There was no leakage from the valve. The customer was satisfied with the product quality. The customer was also satisfied with the delivery speed.
