A new innovation to Greif's butterfly valve is intended for deployment on GCUBE intermediate bulk containers.

 Custom pressure and flow valve components are machined using proprietary tooling to achieve one-directional striations along with all thread-milled internal threads to assure tight sealing.  

Asymmetrical cones for 55-gallon (208-liter) steel or fiber drums facilitate lifting, tilting and dispensing dry contents from drums.
