Features strong sterilization and disinfection capabilities, preventing microbial contamination of the product.
The gasket is made of high-temperature-resistant PTFE composite material.
The gasket, valve body intermediate seal, and stem packing are all made of high-quality PTFE material; this ensures a long service life and corrosion resistance, guaranteeing zero leakage (both internal and external).
The streamlined flow path minimizes pressure loss.
The gasket is replaceable, making disassembly convenient and maintenance costs low.
The design is optimized to eliminate dead zones, effectively reducing the risk of microbial contamination during pharmaceutical production and ensuring reliable aseptic conditions for antibiotic manufacturing.
Precision construction and excellent sealing performance eliminate leakage issues, conserve energy, and foster a clean, efficient production environment.
Reliable materials and precision manufacturing ensure durability; the use of PTFE seals provides superior corrosion resistance. During overhauls, only the gasket needs replacement—facilitating easy disassembly and maintenance, thereby reducing costs and enhancing economic efficiency.
Offers a wide range of applications; it not only serves as a substitute for three-way diaphragm valves at inoculation stations but also performs effectively in process piping—such as on crystallization tanks—within active pharmaceutical ingredient (API) workshops.
Product Applications
Antibiotic shut-off valves are primarily used in sectors such as biological fermentation, pharmaceuticals, and beer brewing. A bottom drain port can be added according to customer requirements. These valves feature high-temperature resistance and a long service life; their dead-leg-free design ensures zero leakage.
