Stainless steel double-union NRV check valve for easy process control
Crafted from premium 304/316L stainless steel, this double-union NRV check valve ensures exceptional corrosion resistance and durability for hygienic applications. Its quick-disassembly design with tri-clamp connections (AS/BS/3A/SMS/DIN compliant) enables effortless maintenance and inspection without pipeline disassembly. The spring-assisted disc mechanism guarantees instant shutoff to prevent backflow, meeting FDA, 3A, and CE certifications for pharmaceutical and food processing systems. Precision-machined surfaces (Ra≤0.8μm) minimize bacterial retention while the compact structure saves installation space in CIP/SIP environments.
For optimal system safety, we recommend clamp gaskets, single-pin heavy duty clamp, and pipe holder to ensure leak-free tri-clamp connections and stable pipeline support.
