API6D Stainless Steel Swing Check Valve
Product Features
Full Bore Design: The internal flow passage of the valve is unobstructed, reducing fluid resistance and pressure loss. Meanwhile, it is convenient for pipeline cleaning and the passage of inspection equipment.
High-Quality Material: The valve body is made of stainless steel materials, such as ASTM A351 CF8M, etc., which has excellent corrosion resistance and high strength and can adapt to a variety of harsh working conditions.
Reliable Sealing: The sealing surfaces of the valve disc and the valve seat adopt metal sealing, with good sealing performance and a long service life. Some models are also equipped with O-rings or RTJ seals to further enhance the sealing effect.
Flexible Installation: It can be installed horizontally or vertically. However, when installed vertically, it is necessary to ensure that the arrow on the valve body points upward.
Convenient Maintenance: Some models support online maintenance, and components such as seals can be replaced without disassembling the entire valve.
Multiple Connection Methods: It provides various end connection forms such as flange connections (RF, FF, RTJ) and welded connections (BW) to meet the installation requirements of different pipeline systems.
Technical Specifications
Nominal Diameter: 1/2"~48" (DN15~DN1200)
Pressure Rating: 150LB~2500LB (PN20~PN420)
Applicable Media: It is suitable for various media such as water, oil, natural gas, and steam.
Working Temperature: -46℃~816℃.
Design Standards: API 6D, ASME B16.34, etc.

Application Fields
Petroleum and Natural Gas Industry: It is used in oil and gas transmission pipelines to prevent the backflow of media and ensure the safe operation of the pipeline systems.
Chemical Industry: In the transmission pipelines of chemical raw materials, intermediates, and products, it prevents the backflow of media and avoids the out-of-control of chemical reactions.
Electric Power Industry: It is used in the cooling water systems and steam systems of power plants to ensure the stable operation of the systems.
Other Industrial Fields: Such as in the papermaking and food processing industries, it prevents the backflow of media and protects equipment and production processes.

What do Class 1500 and WCB actually mean?Class 1500 is a rating category, not a universal operating pressureIn industrial valve practice, 1500LB usually refers to Class 1500. It is a pressure class designation used within an applicable standards framework. It does not mean the valve is automatically
