Chief Features
Ultra-thin design, beautiful appearance, light weight and compact structure, easy to install and use.
The valve is connected by clip-on, and the structure length is short, which can reduce the weight of the entire pipeline system.
The bottom of the gate is smooth without any grooves to ensure that impurities do not accumulate.
The U-shaped sealing strip valve body is inlaid structure, which can prevent leakage caused by the movement of the sealing strip, so that the slurry valve can achieve two-way zero leakage sealing.
The sealing of the valve adopts the side sealing structure, and the two-way sealing is realized on the three sides of the valve plate through the sealing strip embedded in the valve body and keeping smooth and consistent with the surface of the valve body.
The bottom of the valve plate is a semi-circular arc, and after the valve is opened, it is a full flow channel.
No valve cavity structure, the medium will not accumulate.
The flow channel and sealing surface are made of vulcanized wear-resistant rubber, which has better wear resistance and erosion resistance.
