组件规格

定义
A precision-engineered enclosure designed to protect and contain the mechanical and pneumatic/electric components of a sanitary diaphragm valve actuator. It provides structural integrity, environmental protection, and mounting interfaces while maintaining cleanability and compliance with hygienic standards in food, beverage, pharmaceutical, and biotech applications.
工作原理
The housing acts as a rigid framework that contains the actuator's force-generating mechanism (pneumatic piston, electric motor, or spring). It transfers the actuator's output force to the valve stem while protecting internal components from contamination, moisture, and physical damage. In sanitary applications, its smooth, crevice-free design prevents bacterial harborage and facilitates cleaning.
材料
Austenitic stainless steel (AISI 304 or 316L)polished to Ra ≤ 0.8 μm surface finish. Optional electropolishing for enhanced corrosion resistance and cleanability. Gaskets/seals: FDA-compliant EPDMFKM (Viton)or silicone.
Mounting
ISO 5211 direct mounting
IP Rating
IP65/IP67
Surface Finish
Ra ≤ 0.8 μm
Pressure Rating
6-10 bar (operating)
Connection Ports
NPT, G, or ISO pneumatic threads
Temperature Range
-10°C to +120°C
标准
ISO 5211ISO 2852DIN 118503-A Sanitary Standards

常见问题

What are the key differences between standard and sanitary actuator housings?

Sanitary housings feature polished stainless steel, crevice-free designs, validated cleanability, and compliance with 3-A/EHEDG standards. Standard housings may have rough surfaces, seams, and materials unsuitable for hygienic zones.

Can actuator housings be customized for specific valve sizes?

Yes, housings are typically designed for specific actuator models and valve ISO mounting patterns (ISO 5211). Customizations include port locations, mounting brackets, and surface finishes.
