Product Description

The Double  eccentric principle design is adopted to achieve the effect that the sealing face is separated at the opening moment of the butterfly plate and the sealing is performed after contact closing. The valve body adopts thin design, is attractive in appearance, small in size, light in weight and more economical compared with the valves of other diameters. The valve rod excircle adopts coreless grinding and fine grinding, the matching friction coefficient with the packing is small, the friction loss is reduced to the largest extent, and the valve opening and closing torque is greatly reduced. The butterfly plate adopts the double-eccentric design and provides mechanical seal. The sealing does not rely on differential pressure, good sealing performance can be ensured even at low differential pressure, the valve rod is fixed by adopting double bearings, and high rotation accuracy stability is achieved. The bearing adopts stainless steel surface sintering copper with PTFE rolled on the copper surface. The ultra high abrasion resistance and self lubricating functions are achieved, to avoid blocking of the valve and the bearings during long-term use.
