Chief Features
Face to face dimensions adopt short series, and light weight valve is adopted, so as to save pipe supporter.
All port lined PU and it is used to wrap all media in the PU liner to achieve without dead angle.
The seat and disc are designed into a unique self-flushing structure to prevent sedimentation and jamming during the closing process.
The valve with a scraper to clean the valve disc, to prevent the surface of the disc from caking and reduce the switching resistance.
The design of easy to replace consumable parts enables the PU lined and disc to be replaced on site, which is efficient and energy-saving
Points
Polyurethane is a kind of polymer containing urethane type repeating structural unit in the macromolecular chain.
It has super wear resistance. In the immersion state, the wear resistance is 8 times that of cemented carbide steel, 7 times that of vulcanized rubber, and 3 times that of ultrahigh molecular polyethylene.
