Choose from manual, automated, or gear-operated methods for tailored control. Various seat materialsPTFE or metalare offered to handle a spectrum of fluids and temperature conditions, ensuring dependable sealing and durability.
Safety and Performance StandardsDesigned in accordance with API 6D and BS 5351, the valve features a fire-safe design per API 607/BS 6755 and thorough testing to API 598 standards. With its sturdy A352 LCC carbon steel body and high-grade stem materials (A182 F6a, F316, F304), the valve assures reliable operation, mechanical strength, and fire protection in critical applications.
Application Flexibility and BenefitsThe valve is ideal for use in petroleum, chemical, and power plants, handling water, oil, and gas across a wide pressure range (Class 150/300/600). Its full bore construction ensures minimal flow resistance. Epoxy coating offers robust corrosion resistance, supporting long service life even in harsh environments. Flexible end connections (RF, RTJ) and face-to-face dimensions follow ANSI standards, ensuring seamless system integration.
FAQs of SQK A352 LCC Carbon Steel Ball Ball Valve:
Q: How is the SQK A352 LCC Carbon Steel Ball Valve operated?
A: The valve can be operated manually using a lever, with a gear mechanism, or integrated with an actuator for automated control. This flexibility allows it to meet various process requirements and automation levels within industrial facilities.
Q: What standards does this valve conform to for design and testing?
A: The valve is designed according to API 6D and BS 5351 standards, and each unit undergoes stringent testing as per API 598 to ensure sealing integrity and performance. Fire-safe design is validated to API 607 and BS 6755 requirements.
Q: When should I choose PTFE versus metal seat materials for this valve?
A: PTFE seats are ideal for general applications involving non-abrasive fluids and moderate temperatures. Metal seats are recommended for high-temperature, corrosive, or abrasive fluid services, providing enhanced durability and longer life under extreme conditions.
Q: Where can the SQK A352 LCC valve be used?
A: This ball valve is suitable for use in industrial environments such as petrochemical plants, power generation, and chemical processing facilities, as well as applications in water, oil, and gas handling systems.
Q: What is the process for installation and integration with piping systems?
A: The valve features flanged end connections compatible with ANSI B16.5 standards, and has face-to-face dimensions per ANSI B16.10. This allows for straightforward integration into existing or new piping infrastructure following standard installation procedures.
Q: What are the main benefits of a full bore ball valve design?
A: A full bore design minimizes pressure drop and allows for unobstructed fluid flow, reducing energy losses and enabling easy passage for maintenance tools such as pigs, especially in pipeline applications.
