About SQK A216 WCB Cast Carbon Steel Swing Check Valve

SQK A216 WCB Cast 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 Flow Control for Industrial Pipelines

Designed to prevent reverse flow, this swing check valve protects pumps and pipelines in water, oil, and gas applications. The unidirectional flow and non-return operation help maintain system integrity, while the straight body form provides consistent performance and simplifies installation in existing pipework setups.

Engineered for Longevity and Efficiency

Manufactured from robust A216 WCB cast carbon steel and featuring a bolted cover joint, the valve offers high durability and thermal resistance for demanding environments. Its metal-to-metal seating and paint-coated finish ensure minimal maintenance and long life, even under high pressure and temperature conditions.

FAQ's of SQK A216 WCB Cast Carbon Steel Swing Check Valve:

Q: How does the SQK A216 WCB swing check valve prevent reverse flow in an industrial pipeline?

A: This valve operates as a non-return mechanism, automatically closing when fluid attempts to flow backward, ensuring unidirectional movement and protecting pumps and equipment from damage.

Q: What are the benefits of using a metal/metal seat in this check valve?

A: Metal-to-metal seated valves provide enhanced durability, leak-tight sealing, and prolonged service life, especially in high pressure and temperature applications prevalent in industrial settings.

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

A: It is suitable for installation in industrial pipelines handling water, oil, or gas, and its flanged ends allow for secure fitting into straight pipeline sections spanning sizes DN50 to DN600.

Q: What process is followed to ensure the valve's reliability and safety?

A: The valve undergoes stringent testing according to API 598 standards, confirming its leakage class (ANSI Class VI) and verifying performance under working pressures up to PN16 (16 Bar).

Q: When should this swing check valve be used instead of other types?

A: This valve is recommended when low pressure drop and reliable non-return operation are required for protecting downstream equipment from reverse flow in water, oil, or gas pipelines.

Q: How is the face-to-face dimension of the valve determined?

A: The valve's face-to-face dimension conforms to applicable ANSI/ASME standards, guaranteeing interchangeability and proper fitment within standardized piping systems.

Q: What advantage does a paint-coated surface offer for this check valve?

A: The paint-coated surface provides extra protection against corrosion and environmental exposure, extending the valve's operational life and maintaining performance in harsh industrial environments.
