Safety Valves for Pharmaceutical applications manufactured by Darshan Valve & Controls are engineered to satisfy ultra-clean, sanitary processing criteria across biotech and pharmaceutical formulation plants. Fabricated from high-grade electropolished SS316L stainless steel (Ra < 0.4 µm), these sanitary safety relief valves feature crevice-free interiors, FDA-compliant USP Class VI PTFE seals, and sanitary tri-clamp end connections to prevent batch cross-contamination or microbial growth. Designed for full compatibility with Clean-In-Place (CIP) and Sterilize-In-Place (SIP) thermal steam protocols, our pharmaceutical pressure safety valves ensure smooth overpressure discharge, zero seat leakage, and complete pressure protection for fermenters, glass-lined reactors, and sterile storage tanks.
