技术定义与适配语境
典型 执行器阀杆 会按材料、尺寸公差、适配关系和失效风险在 食品制造 中评估。

The actuator stem is a critical linear motion component in food-grade sanitary diaphragm valves that transfers force from the actuator mechanism to the diaphragm, enabling precise control of fluid flow in hygienic processing environments. It operates within sealed systems to prevent product contamination while maintaining consistent pressure regulation.

组件规格

定义
The actuator stem is a critical linear motion component in food-grade sanitary diaphragm valves that transfers force from the actuator mechanism to the diaphragm, enabling precise control of fluid flow in hygienic processing environments. It operates within sealed systems to prevent product contamination while maintaining consistent pressure regulation.
工作原理
Converts rotational or pneumatic force from the actuator into linear displacement, which compresses or releases the diaphragm to open/close the valve orifice. The stem's smooth motion ensures bubble-tight sealing without creating dead zones where bacteria could accumulate.
材料
AISI 316L stainless steel (UNS S31603) with electropolished finish (Ra ≤ 0.8 μm)FDA-compliant PTFE sealsor alternative materials include 1.4404 stainless steel with 2B finish for corrosion resistance in CIP/SIP applications.
Diameter
8-25 mm
Load Capacity
500-5000 N
Stroke Length
10-100 mm
Surface Finish
Ra ≤ 0.8 μm
Pressure Rating
0-16 bar
Operating Temperature
-20°C to 150°C
Straightness Tolerance
0.05 mm/m
标准
ISO 2852DIN 118663-A Sanitary Standards 74-06

常见问题

Why is surface finish critical for food-grade actuator stems?

Electropolished surface (Ra ≤ 0.8 μm) prevents bacterial adhesion, facilitates cleaning, and meets 3-A sanitary standards for food contact surfaces.

How does stem straightness affect valve performance?

Straightness tolerance ≤0.05 mm/m ensures smooth diaphragm compression, prevents uneven wear, and maintains consistent sealing throughout the stem's service life.
