About A352 LCB Carbon Steel Swing Check Valve

A352 LCB Carbon Steel Swing Check Valve

The API BS 1868 series of Swing Check Valves is exceptionally sturdy, rugged and durable, with a reputation for quality, integrity, and long service.

They are designed for tight sealing and ease of operation. The valves are available flanged & butt-weld ends in pressure rating from ASME Class 150 to Class 2500, and in a variety of materials of construction.

Check Valves are of swing-type and bolted-cover construction. They conform to BS 1868 and also meet the general requirements of API 600, including shell wall thickness.

Main features :

Bolted body-cover design, seal welded & Valves with pressure seal cover
Bolted body-cover joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks
Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor
T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598
Rolled ACME thread on the stem for smooth operation
Tapered shoulder on the stem for back seating
Self-aligning type gland assembly with stud-and-nut tightening
Integral hard-faced body seat for globe and check valves
Spring-loaded disc on check valves suitable for no horizontal applications too
Gate and globe valves can be offered with electrical actuators
Austenitic SS forging for body and bonnet of Cryogenic valves, resulting in excellent impact strength, minimal heat loss, and resistance to corrosion
Valves can be offered to NACE MR-0175 and other special NACE requirements

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.

Versatile Application & Durable Build

Designed for use within oil, gas, water, steam, and petrochemical sectors, the A352 LCB Carbon Steel Swing Check Valve is crafted to handle challenging environments and fluctuating temperatures. Its durable LCB carbon steel construction, coupled with bolted bonnet and various seat options, ensures dependability and longevity in both upstream and downstream processes.

Reliable Standards Compliance

This valve adheres strictly to international standards, including ASME B16.5 for flanged connections, ASME B16.10 for dimensions, and ASME B16.34 for design. All testing is performed per API 598 or API 6D, guaranteeing performance for both safety and operational requirements. Leakage class conformity ensures enhanced protection against leakages.

User-Friendly Operation & Maintenance

The swing check valve operates manually and features a non-return mechanism, minimizing maintenance needs and ensuring that flow remains unidirectional. Its swing-type structure and choice of renewable or metal seats enable straightforward maintenance, maximizing operational uptime and service life, even in challenging services.

FAQs of A352 LCB Carbon Steel Swing Check Valve:

Q: How does the swing check valve prevent backflow in pipelines?

A: The swing check valve operates with a swing disc mechanism that allows fluid to flow in one direction only. When flow reverses or stops, the disc swings back to close the valve, effectively preventing backflow and protecting downstream equipment.

Q: What are the key benefits of using A352 LCB Carbon Steel for the valve body?

A: A352 LCB Carbon Steel is known for its excellent toughness at low temperatures, high strength, and resistance to cracking, making it ideal for demanding industries such as oil, gas, and petrochemicals where reliability under extreme conditions is crucial.

Q: Where can this valve be applied?

A: This valve is suitable for a wide range of applications including oil, gas, water, steam, and petrochemical industries. Its robust construction and versatile performance make it ideal for both upstream and downstream process systems.

Q: What is the typical process for installing the swing check valve?

A: Installation involves aligning the flanged ends as per ASME B16.5 with the corresponding pipe flanges, securing them with approved gaskets and bolts, and ensuring correct flow direction. Always follow manufacturer guidelines and industry best practices for safety and reliability.

Q: When is it necessary to renew the seat material in this valve?

A: Seat renewal is typically required when performance decreases due to wear, erosion, or leakage. Using the renewable seat option, maintenance can be executed without replacing the entire valve, minimizing downtime and costs.

Q: How does compliance with API 598 and ASME B16.34 benefit end users?

A: API 598 and ASME B16.34 set stringent guidelines for valve design and testing. Compliance ensures the valve meets high safety, quality, and leakage resistance requirements, translating to reduced risk, increased operational safety, and regulatory confidence.
