About SQK A217 CA15 Cast Alloy Steel Swing Check Valve

SQK A217 CA15 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.

Superior Non-Return Flow Control

Designed as a swing type non-return valve, the SQK A217 CA15 check valve allows fluid to flow in only one direction, automatically preventing backflow. Its robust swing disc mechanism is activated solely by the flow of media, ensuring reliable, maintenance-friendly operation in demanding environments.

Built for Demanding Applications

Constructed from ASTM A217 Gr. CA15 cast alloy steel and finished with anti-corrosive paint, this valve offers exceptional corrosion resistance and durability. It performs optimally in oil, gas, petrochemical, and power plant applications, handling a wide range of temperatures and pressures with consistent reliability.

Quality Tested and Certified

Each valve meets stringent international standards including ASME B16.34 for construction and API 598 for performance testing. It guarantees a high level of leak-proof integrity and is supplied in export standard wooden boxes to ensure safe transport and storage.

FAQ's of SQK A217 CA15 Cast Alloy Steel Swing Check Valve:

Q: How does the SQK A217 CA15 Swing Check Valve operate?

A: This valve operates automatically using a swing disc mechanism. When fluid flows in the correct direction, the disc swings open, allowing passage. If the flow reverses, the disc swings shut, blocking backflow and protecting the pipeline and equipment.

Q: What are the main benefits of using a CA15 cast alloy steel swing check valve?

A: CA15 cast alloy steel provides high corrosion resistance and durability, making these valves suitable for harsh environments. The swing design ensures reliable non-return operation, while compliance with international standards ensures performance and safety.

Q: Where is the SQK A217 CA15 check valve typically installed?

A: This valve is commonly used in pipelines for oil, gas, petrochemical, and power plant applications. It is suitable wherever automatic prevention of reverse flow is needed, handling water, oil, or gas media effectively.

Q: What is the testing and certification process for this valve?

A: The valve is tested in accordance with API 598 standards for leakage and ASME B16.34 for pressure and construction quality. Each valve undergoes rigorous testing to ensure it meets international reliability and safety requirements before shipment.

Q: When should I choose a metal-seated swing check valve like the SQK A217 CA15?

A: Select a metal-seated swing check valve when you require durability against abrasive or corrosive media, and where operating temperatures or pressures are elevated. Its metal seat offers longevity and resistance to wear compared to soft-seated designs.

Q: What size and pressure options are available for this valve?

A: The SQK A217 CA15 swing check valve is available in port sizes ranging from 2 inches to 24 inches (DN50-DN600) and is rated for pressure classes spanning 150 to 600, making it adaptable to various system requirements.

Q: How is the valve packaged and shipped?

A: Each valve is securely packed in an export standard wooden box, ensuring safe handling and transportation to your installation site. This packaging supports safe global distribution and minimizes the risk of damage during transit.
