Description of Actuated Globe Control Valve Gaskets

 

Special features

 

■ Pressure equalization structure: To ensure effective sealing performance, actuated control valve gaskets usually adopt a pressure equalization structure. This structure can balance the pressure inside and outside the valve body and reduce the pressure load on the gasket, thereby extending the service life of the gasket and improving the sealing effect.

 

■ Multi-layer structure: To enhance sealing performance, globe control valve gaskets usually adopt a multi-layer structure. The multi-layer structure allows the gasket to have better sealing and corrosion resistance through a combination of different materials. Common multi-layer structures include metal sandwich gaskets, metal-non-metal composite gaskets, or multi-layer fiber gaskets.

 

■ Adjustable structure: Some actuated globe control valve gaskets have an adjustable structure, and their pressure and size can be adjusted according to actual needs. This adjustability allows the gasket to adapt to different control valve designs and sizes, ensuring a tight fit and effective sealing.

 

■ High-temperature and corrosion-resistant materials:  Common materials include rubber, polytetrafluoroethylene (PTFE), flexible graphite, etc. These materials have good corrosion resistance and high-temperature stability and are suitable for various harsh working conditions.

 

■ Sealing auxiliary materials: To enhance the sealing performance, the actuated globe control valve seal is sometimes equipped with other sealing auxiliary materials, such as sealing gaskets, fillers, or lubricants. These auxiliary materials can fill the tiny gap between the gasket and the valve body, providing a more reliable sealing effect.

 

Application industries

 

Actuated globe control valve gaskets are widely used in various industrial fields, especially in applications where precise control of fluid flow and pressure is required. Here are some common application areas:

 

1. Oil and natural gas industry: During oil and natural gas extraction, transportation, and processing, control valve gaskets are used to control and regulate fluid flow, including oil, gas, and chemicals. 

 

2. Chemical industry: In the chemical production process, control valves are widely used to control the flow and pressure of various chemical substances. Actuated globe control valve gaskets are designed to withstand a variety of corrosive and hazardous chemicals, ensuring safe and reliable operation.

 

3. Power plant: In power plants, control valves are used to control the flow and pressure of media such as steam, gas, and cooling water. Actuated globe control valve seals remain sealed under high temperature and pressure conditions, ensuring the efficiency and reliability of the power generation process.

 

4. Food and beverage industry: In the food and beverage production process, control valves are used to regulate the flow of liquids and gases, such as water, milk, juice, and edible oil. Globe control valve gaskets comply with hygiene standards, ensuring product safety and hygiene.

 

5. Water treatment and wastewater treatment: In water treatment and wastewater treatment systems, control valves are used to control water flow and pressure to achieve processes such as filtration, purification, and distribution.
