Valve Stack-Ups
COIRA can join together valves in any configuration to solve every transfer application you may have. From air locks to a reactor tr precise dosing systems, we are only limited by our imaginations.

Double Valve Stystem
A truly unique valve from COIRA, the only kind in the world! This valve is actually two valves in one. The outside valve can be a butterfly valve or a rotary valve. The inside valve is smaller and can also be either a butterfly or rotary valve. The applications are quite varied. As pictured, with a butterfly outside and rotary inside, the unit can perform accurate dosing from a hopper without an additional feeder system. First, the large butterfly valve opens performing the rough dosing. The butterfly then closes and the small rotary valve finishes the dosing with surprising accuracy.

COIRA specializes in custom valve installations, especially for applications demanding high purity such as the pharmaceutical and food industries. If your company produces high quality equipment that requires sanitary valves or if you are a pharmaceutical or food manufacturer, COIRA has the right valve for your application.
