About SQK A217 C5 Cast Alloy Steel Swing Check Valve

SQK A217 C5 Cast Alloy 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.

Reliable Non-Return Flow Control

Designed with swing-type mechanics, the SQK A217 C5 valve offers automatic protection against reverse flow, safeguarding equipment in demanding environments. Its non-return swing operation ensures efficient shutoff when flow direction changes, reducing system backflow risks without requiring continuous supervision.

Exceptional Material Strength and Finish

Crafted from A217 C5 cast alloy steel, the valve showcases high resistance to corrosion and wear, making it well-suited for high-pressure and high-temperature operations. The industrial-grade paint coating enhances longevity while maintaining performance and appearance across extended service cycles.

FAQ's of SQK A217 C5 Cast Alloy Steel Swing Check Valve:

Q: How does the swing check valve ensure non-return functionality in pipelines?

A: The valve utilizes a swing-type disc that automatically closes when flow reverses, preventing backflow. This mechanism ensures media, such as water, oil, or gas, only moves in one direction, thereby safeguarding pumps and piping systems from damage.

Q: What applications are suitable for the SQK A217 C5 Cast Alloy Steel Swing Check Valve?

A: This valve is ideal for oil, gas, petrochemical, water treatment, and power plant operations, where regulating reverse flow and ensuring system integrity are critical for safety and efficiency.

Q: When should the valve be installed in an industrial piping system?

A: Installation is recommended when there's a need to prevent reverse flow or back pressure, such as before pumps, compressors, or sensitive equipment, ensuring uninterrupted operation and equipment protection.

Q: Where can this swing check valve be used considering its temperature and pressure ratings?

A: With working temperature capacity up to 600C and pressure ratings from Class 150 to 1500, it is well-suited for high-performance applications in refineries, power stations, and processing plants across India and global installations.

Q: What testing standards and certifications does the valve meet?

A: The valve is tested in accordance with API 598, and manufactured to comply with API 6D, ASME, BS EN, ANSI B16.5, and ANSI B16.10 standards, ensuring reliable operation and international compliance.

Q: How does the metal-seated design benefit operational longevity?

A: Metal seats provide superior resistance to abrasion, high temperature, and harsh industrial media, resulting in longer service life and reduced maintenance compared to soft-seated alternatives.

Q: What is the process for maintaining the SQK swing check valve in industrial settings?

A: Routine inspection and cleaning of the disc and seat are recommended, along with periodic function tests based on system usage. The durable coated surface facilitates straightforward maintenance while the manual operation allows for easy accessibility.
