Cast steel ASME B16.34 Swing Check Valves Pressure Seal Bonnet design

The ASME B16.34 Swing Check, and Y Type Swing Check Valves feature a pressure seal bonnet design for high-pressure services. These valves are extensively used in high pressure and high-temperature steam, oil, gas, chemical, and water applications in thermal power plants, fertilizer plants, petrochemical plants, and refineries. These valves are available in butt weld ends in pressure ratings of Classes 900, 1500 and 2500, and come in carbon steel and alloy steel construction.

Advanced Design for Critical Environments

Designed according to API 6D and ASME B16.34 standards, this swing check valve handles extremely high pressures (Class 2500 / 425 Bar) and temperatures, making it ideal for applications requiring reliable backflow prevention in harsh conditions. The bolted cover design enhances maintenance accessibility and structural integrity.

Superior Materials and Surface Protection

Choose from forged steel, stainless steel, or alloy steel construction, ensuring compatibility with various media and temperature requirements. An anti-corrosive smooth finish provides long-lasting durability, making the valve suitable for corrosive environments in oil, gas, and petrochemical processes.

Versatile End Connections for Seamless Integration

Available with flanged, butt weld, or socket weld ends, the valve adapts easily to different piping configurations. Compliance with ASME B16.10 face-to-face dimensions ensures straightforward installation and replacement, minimizing downtime in high-value operations.

FAQ's of Class 2500 Swing Check Valve:

Q: How does the Class 2500 Swing Check Valve prevent backflow in industrial systems?

A: The valve utilizes a swing-type disc mechanism that automatically closes when reverse flow occurs, thus preventing backflow and protecting downstream equipment. Its unidirectional flow design and non-return functionality ensure efficient operation in high-pressure applications.

Q: What materials are available for this valve, and how do I choose the right one?

A: You can select from forged steel, stainless steel, or alloy steel, depending on your application's pressure, temperature, and corrosive media requirements. Material choice impacts the valve's temperature resistance (up to 600C) and durability in specific environments.

Q: Where is this swing check valve typically installed?

A: It is designed for high-pressure pipelines in steam, oil and gas industries, and petrochemical plants, commonly used in applications demanding dependable non-return performance and reliable sealing under extreme conditions.

Q: What is the leakage class of the valve and how is it tested?

A: The valve meets ANSI/FCI 70-2 leakage class standards and is tested according to API 598 protocol. These standards ensure strict quality control, verifying minimal leakage and optimal sealing performance under specified pressures.

Q: How do I maintain or service a bolted bonnet swing check valve?

A: The bolted bonnet design allows for easy removal of the cover, enabling straightforward access to internal components for inspection, cleaning, or replacement. Regular maintenance helps preserve performance in critical applications.

Q: What are the advantages of using resilient versus metal-to-metal seats in the valve?

A: Metal-to-metal seats offer superior temperature and pressure tolerance, suitable for high-demand applications. Resilient seats provide enhanced sealing and reduced leakage, ideal for applications requiring tight shutoff, especially in lower pressure or less abrasive media systems.
