The Characteristics of Stainless Steel Trunnion Mounted Ball Valves
2024-03-28

Stainless steel trunnion mounted ball valve is a commonly used valve type, usually used to control the flow of fluids (such as water, gas, steam, etc.) in pipelines. Advantages: 1. High-pressure resistance. 2. Corrosion resistance due to stainless steel material. 3. Excellent sealing performance with advanced sealing technology. 4. Using PEEK valve seats, zero leakage, and light torque. 5. Robust structure for high reliability. 6. Convenient operation, including remote control, enhancing system efficiency. 7. Wide applicability across industries such as petroleum, chemical, natural gas, and metallurgy. Stainless steel trunnion mounted ball valve is a reliable valve type suitable for various industrial scenarios, especially in environments that require corrosion resistance and high temperature resistance accompanied by corrosion.

Introduction to Angle Globe Valve
Introduction to Angle Globe Valve
2024-03-06

Angle globe valve is a common pipeline valve designed with a special angle structure to provide more flexible and effective fluid control. 1. Structural features: The main feature of an angle globe valve is that its valve body is designed in an angular shape, usually 90 degrees or other specific angles. This is different from traditional through type globe valves. The angled structure makes the valve move more smoothly when closing and opening, while reducing the resistance of fluid passing through. 2. Working principle: The working principle of the angle globe valve is basically similar to that of a general globe valve. The valve opens and closes the valve disc by rotating, thereby regulating the fluid flow in the pipeline. The valve structure with angular design helps to reduce the resistance of fluid flow and improve flow efficiency. 3. Scope of application: Angle globe valves are widely used in pipeline systems in various fields, including industry, chemical industry, HVAC, water supply and drainage systems, etc. Its design features make it more suitable for situations that require high fluid flow efficiency or are installed at an angle. 4. Operation mode: The angle globe valve can be operated manually, electrically, or pneumatically. Manual operation is suitable for some small systems, while electric and pneumatic operation are more suitable for large systems, improving the convenience and automation of operation. 5. Advantages: High flow efficiency: Angular design helps to reduce the resistance of fluid flow and improve the flow efficiency of pipeline systems. Smooth operation: The angle structure of the valve makes the opening and closing movements smoother, reducing operational resistance. Strong adaptability: suitable for various pipeline systems, especially in some working conditions with strict requirements for fluid flow efficiency, it performs better. 6. Application scenario: Angle globe valves are commonly used in situations that require frequent fluid regulation, such as industrial and chemical production processes that require regular fluid shut-off or regulation in pipeline systems. In summary, angle globe valves play an important role in pipeline control due to their unique angle design, providing an efficient and flexible solution for fluid control.

Introduction to Bellows Globe Valves
Introduction to Bellows Globe Valves
2024-03-01

The bellows globe valve is a commonly used valve in pipeline systems, designed with a bellows structure that imparts greater flexibility to the valve. 1. Structural Features: The main characteristic of the bellows globe valve lies in its use of bellows as the sealing element. Bellows is a flexible metal tube formed by multiple layers of corrugations, offering high bending and flexing capabilities. This structural design allows the bellows globe valve to better accommodate the bending and expansion of pipelines during operation, thereby enhancing the valve's reliability and durability. 2. Sealing Performance: The bellows portion of the bellows globe valve serves as the sealing element, providing excellent sealing performance. Due to the flexible deformation capability of the bellows, it can better conform to the valve seat when the valve is closed, ensuring a tight seal and effectively preventing media leakage. 3. Application Range: This type of valve is suitable for general industrial pipelines, HVAC (Heating, Ventilation, and Air Conditioning) systems, water supply and drainage systems, and other fields. Due to the special structure of its bellows, the bellows globe valve is particularly well-suited for situations where consideration of pipeline bending and expansion is necessary. 4. Operation Method: Bellows globe valves are typically operated manually, electrically, or pneumatically. Manual operation is suitable for small-scale systems, while electric and pneumatic operation are more applicable to large-scale systems, enhancing convenience and automation in operation. 5. Advantages of Use: The bellows globe valve offers superior adaptability and sealing performance compared to traditional globe valves. Additionally, its simple structure and easy maintenance contribute to reduced operational costs. In general, the bellows globe valve, with its distinctive bellows structure, is widely employed in pipeline systems, offering a more reliable and efficient valve solution for industrial and construction sectors.
