Versatile Mounting and Connection Options

Choose panel or inline mounting for installation flexibility. The valve accommodates both BSP/NPT threaded ends and flanges, enabling seamless integration into diverse vacuum service setups. This adaptability ensures compatibility across different pipes and system requirements.

Reliable Performance in Extreme Conditions

Constructed from stainless steel with PTFE sealing, the SQK ball valve withstands harsh environments, handling media temperatures from -20C to 200C. Its polished finish and sturdy PVC-covered handle enhance longevity, operating efficiently with air, inert gases, and non-corrosive liquids.

Tested for Maximum Leak-Tightness

Each ball valve undergoes a Helium Leak Test to certify its superior sealing performance, achieving leakage rates as low as <= 1 x 10^-9 mbar l/s. This stringent testing ensures the product maintains integrity and safety within high-vacuum applications.

FAQ's of SQK Vaccum Service Ball Valve:

Q: How is the SQK Vacuum Service Ball Valve tested for leakage?

A: The valve is rigorously assessed using a Helium Leak Test, which measures and confirms leakage rates of <= 1 x 10^-9 mbar l/s. This process guarantees optimal sealing for reliable vacuum service.

Q: What media can be used with this ball valve?

A: It is suitable for air, inert gases, and non-corrosive liquids. The stainless steel construction and PTFE sealing offer broad compatibility for these media under vacuum conditions.

Q: When should I choose a one, two, or three-piece body design?

A: One-piece bodies offer compactness and basic maintenance, while two- and three-piece designs provide easier in-situ servicing and cleaning-ideal for applications demanding quick disassembly or thorough maintenance.

Q: Where can I mount the SQK Vacuum Service Ball Valve?

A: The valve supports both panel and inline mounting, providing the flexibility to integrate into various vacuum systems and layouts, depending on application needs.

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

A: Installation involves selecting the appropriate end connection (BSP/NPT threads or flange), mounting the valve in panel or inline configurations, and ensuring alignment with system channels for secure operation.

Q: How does the quarter-turn operation benefit users?

A: The quarter-turn design offers swift opening and closing with minimal effort, enhancing operational speed and reducing manual fatigue during regular use.

Q: What are the benefits of the valve's tested leak-tightness?

A: Assured leak-tightness minimizes system contamination, supports safety in sensitive environments, and improves efficiency by maintaining stable vacuum pressure levels.
