Robust Construction and Versatility

Manufactured from ASTM A216 WCC cast carbon steel, this gate valve features a straight, bolted bonnet design for enhanced strength and leak resistance. Its flexible or solid wedge disc options allow reliable performance across a range of media-including water, oil, gas, and steam-making it suitable for demanding industrial settings.

Comprehensive Standards Compliance

Complying with globally recognized standards (API 600, BS 1414, ASME B16.34), and tested as per API 598, the SQK gate valve ensures safety and reliability. The face-to-face, flange, and welding dimensions meet ASME B16.10 and B16.5/16.25 requirements, ensuring compatibility with most piping systems.

Superior Corrosion and Temperature Resistance

Epoxy or enamel painting protects the exterior against harsh environments, while metal-to-metal seating and robust gland packing (graphite/PTFE) handle a wide temperature range from -29C to +425C. These features significantly extend service life and minimize maintenance.

FAQ's of SQK A216 WCC Cast Carbon Steel Gate Valve:

Q: How does the SQK A216 WCC Cast Carbon Steel Gate Valve ensure leakage prevention?

A: The valve employs a robust bolted bonnet structure, metal-seated design (Stellite coated or 13Cr), and high-quality gland packing materials like graphite or PTFE. Together, these features offer exceptional sealing, minimizing leaks even under high pressures and varying temperatures.

Q: What types of operations are available for this gate valve?

A: The valve can be operated manually by handwheel for smaller sizes, and for larger diameters, gear or bevel gear mechanisms are provided to ensure effortless and precise flow control, meeting diverse installation needs.

Q: When should a flexible wedge be chosen over a solid wedge for this valve?

A: A flexible wedge is preferable when the pipeline is subject to frequent thermal expansion or contraction, as it adapts better to pipeline movements and misalignments. A solid wedge provides rigid sealing and is suitable for consistent temperature and pressure conditions.

Q: Where can the SQK WCC gate valve be used?

A: It is suitable for a wide range of applications, including industrial pipelines, petrochemical facilities, refineries, and power plants-particularly where precise control of water, oil, gas, or steam flow is essential.

Q: What is the process for testing these valves before delivery?

A: Each valve undergoes rigorous hydrostatic and pneumatic pressure tests as per API 598 requirements, ensuring structural integrity and reliable performance before leaving the manufacturing facility.

Q: How does the epoxy or enamel body coating benefit the valve?

A: These coatings provide enhanced resistance to corrosion, moisture, and harsh chemicals, thereby extending the valve's operational lifespan and reducing maintenance frequency in aggressive environments.
