Face to face dimensions adopt short series, and light weight valve is adopted, so as to save pipe supporter.
The completely open channel can prevent the medium from depositing.
The newly developed U-shaped sealing ring can ensure the good sealing.
The external sealing of the disc is realized by embedding the elastic sealing strip in the valve body, and can be adjusted.
by means of screws and plates.
Low flow resistance.
Easy installation and maintenance.
