FAQ's of SQK A182 FSS304 Stainless Steel Swing Check Valve:

Q: How is the SQK A182 FSS304 Swing Check Valve installed in a pipeline system?

A: This swing check valve is designed for horizontal installation with flanged end connections, making it easy to mount into pipelines with compatible flange standards according to ASME B16.10 dimensions.

Q: What are the main benefits of using a stainless steel (SS304) swing check valve in industrial processes?

A: The SS304 material offers excellent corrosion resistance, durability, and strength. This ensures long-lasting performance, minimal maintenance, and reliable protection against backflow in water, oil, and gas applications.

Q: When should a soft seat be requested for this valve, and what advantage does it offer?

A: A soft seat is recommended for applications requiring highly bubble-tight sealing. It provides zero leakage, which is critical in systems handling sensitive or hazardous media, ensuring enhanced safety and operational reliability.

Q: Where can the SQK A182 FSS304 Swing Check Valve be used effectively?

A: It is suitable for use in pipeline flow control across various sectors, including industrial processes, water treatment, oil refineries, and gas distribution systems in both domestic and export markets.

Q: What is the process of valve operation in this swing check design?

A: The valve operates automatically; the disc swings open or closed in response to the flow direction, allowing the media to pass when flowing in the correct direction and preventing reverse flow without manual intervention.

Q: What sizes and pressure ratings are available for this valve model?

A: This model is available in port sizes ranging from DN25 (1 inch) to DN300 (12 inches) with pressure ratings of PN16/Class 150, making it versatile for a wide range of pipeline requirements.
