I. Overview of J-Valves 20-inch 150LB Flanged Gate Valves
The J-VALVES 20-INCH 150LB FLANGED GATE VALVE is a valve specifically designed for high-pressure working conditions. Its main features are as follows:
• Large Diameter Design: With a diameter of 20 inches, it can meet the pipeline requirements for large flow rates and is suitable for high-pressure transmission systems in industries such as petroleum, natural gas, and chemical engineering.
• High-Pressure Performance: The pressure rating of 150LB ENSURES THAT THE VALVE can operate stably under high-pressure environments, while also possessing good sealing performance and durability.
• Flange Connection: It adopts the flange connection method, which is convenient for installation and maintenance and also complies with internationally common pipeline connection standards.
II. Introduction to API/ASME Standards
API (American Petroleum Institute) and ASME (American Society of Mechanical Engineers) are internationally recognized authoritative standard-setting organizations, and the standards they issue have extensive guiding significance in valve design, manufacturing, and testing.
• API 600: This standard stipulates the design, manufacturing, and testing requirements for steel flanged and butt-welding gate valves, and is applicable to valves with nominal pressures of PN16 - PN40 (Class 150 - 600).
• ASME B16.5: This standard mainly stipulates the dimensions, tolerances, and connection requirements of pipeline flanges, and is applicable to flange connections with nominal pressures not exceeding 2500LB.
• ASME B16.10: This standard stipulates the face-to-face dimension of valves to ensure the installation compatibility of valves in pipeline systems.
III. Comparison of the Design of J-Valves 20-inch 150LB Flanged Gate Valves with API/ASME Standards
(1) Structural Design
Design Features | J-Valves 20-inch 150LB Flanged Gate Valve | API 600 | ASME B16.10 |
Valve Body Material | High-strength alloy steel | Meets the requirements of API 600, usually carbon steel or alloy steel | No specific requirements, but it needs to meet the overall strength of the valve |
Valve Type | Flanged gate valve | Flanged gate valve | Applicable to multiple valve types, including gate valves |
Face-to-Face Dimension | Complies with ASME B16.10 standard | No specific regulations, but needs to comply with relevant face-to-face dimension standards | Specifies the face-to-face dimension of the valve in detail |
Flange Connection | Complies with ASME B16.5 standard | Complies with ASME B16.5 standard | No specific regulations, but needs to comply with relevant flange standards |
The J-VALVES 20-INCH 150LB FLANGED GATE VALVE adopts an elastic gate design and a backseat to ensure the sealing performance of the valve under high-pressure conditions. Its sealing material uses overlay welding 507/507MO, which has good wear resistance and corrosion resistance. The sealing test is strictly carried out in accordance with the API 598 standard to ensure the sealing reliability of the valve in actual use.
(3) Stem Design
Design Features | J-Valves 20-inch 150LB Flanged Gate Valve | API 600 |
Stem Material | Integrally forged, high-strength alloy steel | Integrally forged, meeting the requirements of API 600 |
Stem Thread | Trapezoidal thread, left-hand | Complying with ASME B1.5 or ASME B1.8 standards, trapezoidal thread, left-hand |
Stem Connection | T-shaped end connection to prevent the stem from rotating or disengaging from the gate | T-shaped end connection, meeting the requirements of API 600 |
The stem of the J-VALVES 20-INCH 150LB FLANGED GATE VALVE is made by an integrally forged process to ensure its strength and reliability. The thread of the stem adopts a trapezoidal thread, which complies with the ASME B1.5 or ASME B1.8 standards. The left-hand design ensures that the valve closes when rotated clockwise. The connection of the stem adopts a T-shaped end connection, effectively preventing the stem from rotating or disengaging from the gate during use.
