About SQK A351 CF8 Stainless Steel Swing Check Valve

SQK A351 CF8 Stainless 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.

Durable Construction for Industrial Demands

Manufactured from premium A351 CF8 stainless steel, this swing check valve promises consistent performance in harsh environments. Its robust metal-to-metal sealing and polished surface ensure both long-lasting reliability and resistance to corrosion, making it an optimal choice for industrial fluid management.

Seamless Integration with Flanged Ends

Designed with ANSI-standard flanged ends, the SQK swing check valve enables straightforward installation into new or existing pipelines. Its swing type mechanism and manual operation facilitate efficient backflow prevention without external power, reducing complexity and maintenance needs.

FAQ's of SQK A351 CF8 Stainless Steel Swing Check Valve:

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

A: The SQK swing check valve is engineered with a swinging disc that opens with forward flow and closes automatically when flow stops or reverses, effectively preventing backflow and ensuring media flows in only one direction.

Q: What applications are suitable for a CF8 stainless steel swing check valve?

A: This valve is ideal for industrial fluid control involving water, oil, and gas where non-return functionality is critical. Its stainless steel body and high-pressure tolerance make it suitable for demanding environments such as chemical processing, petroleum, and general manufacturing.

Q: When should a metal-to-metal seal swing check valve be used?

A: A metal-to-metal seal is recommended when higher durability and resistance to wear and chemicals are required, as it withstands aggressive media and extreme temperatures up to 200C, making it suitable for industrial and process applications.

Q: Where can the SQK A351 CF8 swing check valve be installed?

A: This valve is designed for integration into pipelines with flanged connections, often found in large-scale industrial plants, utility systems, and infrastructure requiring ANSI-standard fittings throughout India and international markets.

Q: What is the installation process for this flanged-end swing check valve?

A: Installation involves aligning the valve's flanged ends with the pipeline flanges and bolting them together using appropriate gaskets, ensuring a tight, leak-proof connection according to ANSI specifications. No external power source or actuator is required.

Q: What are the primary benefits of choosing a CF8 stainless steel check valve?

A: Key advantages include excellent corrosion resistance, mechanical strength, a long service life, and reliable performance under a wide temperature and pressure range, all of which translate to reduced maintenance and operational downtime.
