Product description

LT-type butterfly valve drive mode can be used manually, worm, pneumatic, electric, connection can choose flange, the folder, the structure can choose a single eccentric, midline, double eccentric, three eccentric, sealed structure can choose soft seal, , The pressure range PN0.1-10MPa , nominal diameter of DN40 ~ 2000mm , material available cast steel, stainless steel. As the use of the valve is very wide range, the same kind of valve in different occasions and conditions have different match.
 

LT-type butterfly valve for food, medicine, chemical, oil, electricity, metallurgy, urban construction, textile, paper and other water supply and drainage, gas pipeline for regulating the flow and the role of interception medium, its main features are: 
 1,  Unique structure, light weight, opening and closing quickly. 
 2, the operating torque is small, easy to operate, effort Qiong Qiao. 
 3, can be installed anywhere, convenient. 
 4, the seal can be replaced, sealing performance and reliable, to achieve two-way seal zero leakage. 
 5, sealing materials resistant to aging, corrosion resistance, long service life and so on. 
 6, simple structure, good interchangeability, low prices. 
 7, stem seal is not easy to deformation so as to avoid the usual valve stem leakage phenomenon. Overall support is good, stable, solid. 
 8, the seat rubber with less, the potential impact of expansion is small, easy to control the torque value in the appropriate range of two-way stem without pin connection, simple and compact structure, easy to remove. 
 9, butterfly plate with automatic pairing, to achieve the butterfly plate and the valve seat with a small amount of co-operation. Phenolic back seat with no shedding, tensile, anti-leakage, easy to change and so on. As the valve seat sealing surface and the back as a whole, thereby reducing the amount of deformation of the valve seat.
