Vacuum Valve FAQ Section 1
What materials are used in your vacuum valves?
Our vacuum valves are constructed from high-grade 316L stainless steel for the body components, with elastomer or metal seals depending on the specific model and application requirements. The sealing materials include Viton®, Kalrez®, and copper for ultra-high vacuum applications. All materials are carefully selected for minimal outgassing and maximum chemical resistance.
How often should vacuum valves be maintained?
Regular maintenance intervals depend on usage conditions, but we generally recommend inspecting vacuum valves every 6-12 months for normal operating conditions. In high-cycle or harsh environments, quarterly inspections may be necessary. Maintenance typically involves seal inspection, cleaning of sealing surfaces, and verification of proper actuator function.

Vacuum Valve FAQ Section 2
What flange types are available for your vacuum valves?
We offer vacuum valves with all standard vacuum flange connections including KF (NW), ISO, CF, and ASA flanges. The most common sizes range from DN16 to DN250 (NW16 to NW250). Custom flange configurations can be manufactured for special applications, with lead times varying based on complexity.
Can your valves handle aggressive chemicals?
Yes, our vacuum valves are specifically designed to handle aggressive media. We offer special versions with PTFE coating, all-metal construction, or chemical-resistant elastomers for applications involving corrosive gases, solvents, or other reactive substances. Please consult our technical team for specific chemical compatibility requirements.
Customization Options
- Material selection (stainless steel, aluminum, special alloys)
- Surface treatments (electropolishing, passivation, coatings)
- Port configurations and orientations
- Actuation methods (manual, pneumatic, electric, hydraulic)
- Special seals for extreme temperatures or cleanroom requirements
Vacuum Valve FAQ Section 3
What is the lead time for standard vacuum valve models?
Standard vacuum valve models typically ship within 2-3 weeks from order confirmation. Express delivery options are available for urgent requirements. Custom configurations may require 4-6 weeks depending on the specific modifications needed. We maintain strategic inventory of our most popular models to ensure quick delivery.
Do you provide vacuum testing data with each valve?
Yes, every vacuum valve ships with complete test documentation including leak rate measurements, pressure holding tests, and functional verification reports. Our quality control process includes 100% testing of all critical parameters to ensure performance meets or exceeds specifications.
Maintenance Procedures
- Isolate the valve from the vacuum system
- Vent the chamber to atmospheric pressure
- Remove the valve according to manufacturer instructions
- Inspect all sealing surfaces for damage or contamination
- Clean components with appropriate solvents
- Replace worn seals or damaged parts
- Reassemble and perform leak testing before returning to service
