NAI-LOK 3" 150# EP Flange Y Type Non-Return Valve | Ultra High Purity, ASME B16.5, Electropolished SS316L
EP Grade for Ultra High Purity:Valve interior isElectropolished (EP)to an ultra-smooth surface, minimizing particle adhesion and bacterial growth to ensure fluid integrity in critical applications.
Certified Material & Construction:Manufactured from 316L Stainless Steel with full material traceability. Complies with ASME B16.5 and meets stringent industry standards for high-purity systems (e.g., SEMI, cGMP).
Sanitary Swing Check Design:Optimized swing check mechanism with minimal dead legs promotes full drainage and prevents fluid entrapment, crucial for preventing cross-contamination.
High-Cleanliness Packaging:Valves are cleaned, dried, and bagged in a controlled environment per industry standards (e.g., IEST, ASTM) to deliver particle-free.
