J-VALVES 60-inch 150LB CA15 Large Diameter Flanged Gate Valve

I. Design Standards and Specifications
The gate valve is strictly designed and manufactured in accordance with the API 600 standard, covering various requirements such as structural length and connection dimensions. The flange connection dimensions comply with the ASME B16.47 standard, ensuring precise matching with the pipeline system and enhancing sealing performance and safety.

II. Analysis of Structural Features

• Valve Body Design: Adopts a robust structure, incorporating fluid dynamics principles to reduce resistance. The wall thickness distribution is optimized through finite element simulation analysis, ensuring no deformation or damage under 150LB pressure and guaranteeing long-term stable operation.

• Gate Structure: Utilizes a wedge-type elastic gate, which achieves sealing by fitting the valve seat through elastic deformation when closed. The sealing surface is surfacing-welded with hard alloy to enhance wear resistance and corrosion resistance, adapting to frequent opening/closing and harsh environments.

• Driving Methods: Can be equipped with multiple driving methods such as manual, worm gear, electric, or pneumatic, respectively suitable for scenarios with different operating frequencies, control accuracies, and automation requirements.

III. Considerations for Material Selection

• Valve Body Material: CA15 cast steel has excellent comprehensive performance, with moderate carbon content, combining strength and toughness. It can withstand high pressure and impact force, maintains stable performance at high temperatures, and is suitable for the transportation of various industrial media.

• Sealing Material: Selected according to the characteristics of the medium. Rubber or PTFE is used for conveying general media, while metal sealing materials are chosen for special working conditions to ensure stable sealing performance.

• Valve Stem Material: High-quality alloy steel is selected, undergoing heat treatment and anti-corrosion treatment to ensure strength, corrosion resistance, and operational flexibility, thereby extending service life.

IV. Application Fields

• Energy and Power Industry: Used in main steam, feed water, and circulating water systems of thermal power plants, as well as key parts of hydropower stations, ensuring stable and efficient operation of units.

• Petroleum and Chemical Industry: Applied in pipelines for transporting crude oil, chemical raw materials, and products, meeting the stringent requirements of conveying high-temperature, high-pressure, and corrosive media.

• Water Conservancy and Municipal Engineering: Suitable for urban water supply and drainage systems and flood control water conservancy projects, realizing zoning control, maintenance isolation, and water flow regulation.

V. Highlighted Performance Advantages

• Excellent Sealing Performance: The combination of unique structure and high-quality materials results in a leakage rate far lower than industry standards, preventing medium leakage.

• Low Fluid Resistance: Optimized flow channel design reduces resistance, improves conveying efficiency, and minimizes energy consumption and system pressure loss.

• Easy and Flexible Operation: Multiple driving methods enable easy operation to meet the needs of different scenarios.

• Long Service Life: High-quality materials, advanced craftsmanship, and strict quality control reduce the frequency of maintenance and replacement, lowering operating costs.
