Ball Valves for Pharmaceutical

Standard industrial ball valves are not GMP-compliant because they have body cavities that trap product (causing cross-contamination between batches), unpolished internal surfaces that harbour microorganisms and product residue, and elastomer seats that may not meet USP Class VI biocompatibility. Pharmaceutical GMP ball valves must use: SS 316L body electropolished to Ra ≤0.4 µm or better, USP Class VI PTFE seats, cavity-free (drainable) body design, and full material traceability documentation. Always specify ASME BPE-compliant ball valves for pharmaceutical product contact service.

The two dominant connection types in pharmaceutical piping are: (1) Tri-clamp / sanitary clamp connections (DIN 32676, ISO 2852) — quick-disconnect flanges with clamp and gasket, used where frequent disassembly for inspection or cleaning is required, such as at filter housings and centrifuge connections; (2) Orbital weld connections (ASME BPE OD tubing dimensions) — permanent full-penetration welds made with an orbital welding machine, used for all permanent piping in WFI and sterile product distribution. Threaded connections are not GMP-acceptable for product contact due to dead leg and crevice concerns.
