Key Features
Construction Details
Each Plug Valve is manufactured from high-grade stainless steel:
- Valve Body, Plug, and Cover: Crafted from AISI 316L or AISI 304L stainless steel.
- Surface Finish: Product-contact surfaces polished to Ra ≤ 0.8 μm for optimal hygiene.
- Plug Coating: The plug undergoes hard-chrome coating, followed by precision grinding and lapping to ensure smooth operation, leak-free performance, and extended service life.
- Sealing Materials:
- EPDM (FDA compliant) for rubber seals
- PTFE for the thrust washer
This meticulous attention to detail delivers superior durability and leak-tight functionality in demanding sanitary environments.
