Our Bellow Sterile Valve, also known as the sanitary bellow control valve, is a hygienic valve designed for sterile applications.  It uses a flexible metal bellow to completely seal the valve stem from the process media, preventing contamination and leakage while allowing safe and clean flow control.  The bellow expands and contracts as the valve opens or closes.

Bellow sterile valves are usually made of 316L stainless steel and have polished surfaces to reduce bacterial growth.  They are available in manual or pneumatic actuation options, depending on process control requirements.
