About SQK A352 LCC Carbon Steel Swing Check Valve

SQK A352 LCC 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.

Superior Material Quality

Crafted from ASTM A352 LCC carbon steel, this swing check valve exhibits excellent toughness and resistance to low-temperature impacts. Anti-corrosive surface painting ensures longevity, even in aggressive operating environments, while the use of premium carbon steel components enhances structural integrity and operational dependability.

Compliance with International Standards

The SQK A352 LCC Swing Check Valve adheres to global standards, including API 6D, ASME B16.34, and face-to-face measurements per ASME B16.10. Rigorous API 598 testing certifies its performance and reliability, making it a trusted choice for critical applications in oil & gas, chemicals, and waterworks.

Versatile Applications and Installation

This valve supports a breadth of working mediawater, oil, steam, and chemicals. Its full bore design lowers pressure drop, while compatibility with both flanged and butt weld connections allows flexible installation in horizontal pipelines. Manual swing operation supports precise flow regulation in various industrial settings.

FAQs of SQK A352 LCC Carbon Steel Swing Check Valve:

Q: How is the SQK A352 LCC Carbon Steel Swing Check Valve installed?

A: The valve is designed for horizontal installation and supports both flanged and butt weld end connections. Proper alignment and secure bolting or welding are necessary to ensure leak-free service. Following installation guidelines in accordance with ASME and API standards is recommended.

Q: What are the main benefits of using this swing check valve in industrial applications?

A: The SQK A352 LCC Swing Check Valve offers reliable backflow prevention, excellent corrosion resistance due to its anti-corrosive painting, and robustness under varying pressures and temperatures. Its full bore structure minimizes flow resistance, making it ideal for oil & gas, petrochemical, and waterworks environments.

Q: When should I choose a soft seat versus a metal seat for the valve?

A: A soft seat provides superior sealing in low-pressure or clean media applications to minimize leakage. For high-temperature, abrasive, or corrosive applications, a metal seat is preferable due to its durability and resistance to wear.

Q: Where can this check valve be applied effectively?

A: This valve is suitable for use in pipelines carrying water, oil, steam, or chemicals, commonly found in the oil & gas, petroleum, chemical processing, and waterworks sectors.

Q: What is the recommended working temperature range for this valve?

A: The valve operates reliably between -29C and 425C, making it suitable for services ranging from chilled water to high-temperature steam and process fluids.

Q: How does the swing check mechanism function?

A: The swing check design allows the disc to swing open as fluid flows in the correct direction, and close automatically to prevent reverse flow, protecting pumps and equipment downstream.
