FAQ's of SQK Oxygen Service Ball Valve:

Q: How is the SQK Oxygen Service Ball Valve tested before delivery?

A: Every valve undergoes rigorous 100% factory testing to ensure optimal performance, leak tightness in compliance with ANSI Class VI standards, and adherence to oxygen service requirements.

Q: What are the benefits of using a PTFE seal material in this ball valve?

A: PTFE seals offer excellent chemical resistance, low friction, and minimal reactivity with oxygen, reducing contamination risk and promoting long-term valve reliability in sensitive environments such as hospitals and industrial gas systems.

Q: Where can the SQK Oxygen Service Ball Valve be installed?

A: This valve is suitable for oxygen pipelines in medical facilities, industrial gas supply systems, and similar settings requiring safe, hygienic handling of oxygen gas at pressures up to 40 Bar.

Q: What is the recommended process for installing this valve?

A: Use compatible screwed, threaded, or flanged connections per BSP, ISO, or ANSI standards. Ensure the system is clean and oil-free to prevent contamination, and refer to installation guidelines for proper handling of nickel-plated forged brass valves.

Q: When should the anti-static device and blow-out proof stem features be considered?

A: These safety features are especially critical during operation in oxygen-rich environments, providing enhanced protection against static discharge and accidental stem removal, thereby guaranteeing safe and uninterrupted service.

Q: What is the distinct usage advantage of the blue oxygen service marking?

A: The blue marking provides clear visual identification for oxygen service, reducing the risk of cross-contamination and improving safety during maintenance and operation in multi-gas environments.
