组件规格

定义
A critical cylindrical component in aseptic filling valve assemblies that moves linearly to open/close fluid pathways, maintaining sterility by preventing microbial ingress during beverage filling operations. It interfaces with seals and actuators to control product flow with minimal contamination risk.
工作原理
Operates through linear actuation (pneumatic/hydraulic) to displace within a sealed chamber, creating a barrier that opens/closes fluid ports. In closed position, it blocks product flow; when retracted, allows precise filling while maintaining aseptic conditions via sterile barrier systems.
材料
AISI 316L stainless steel (UNS S31603) with electropolished finish (Ra ≤ 0.4 μm)alternative: ceramic-coated titanium for corrosive applications.
Diameter
8-25 mm
Stroke Length
15-50 mm
Surface Finish
Ra ≤ 0.4 μm
Temperature Range
0-130°C
Operating Pressure
0-6 bar
CIP/SIP Compatibility
Yes
标准
ISO 2852DIN 11866FDA 21 CFR 177EHEDG

常见问题

What materials are suitable for aseptic valve stems?

AISI 316L stainless steel is standard for corrosion resistance and cleanability. Ceramic coatings or titanium may be used for highly corrosive products.

How does the stem maintain sterility during operation?

Through precision machining with Ra ≤ 0.4 μm finish, proper seal integration, and compatibility with Clean-in-Place/Sterilize-in-Place (CIP/SIP) processes.

What standards apply to these components?

ISO 2852 for aseptic connections, DIN 11866 for dairy fittings, FDA regulations for food contact, and EHEDG guidelines for hygienic design.
