D371X LT Butterfly Valve product description
D371X LT Butterfly Valve produced and sold by Baigang valve group drive mode optional manual, worm gear, pneumatic, electric, connection options flange, the folder, the structure can be used single eccentric, the center line, double eccentric, three eccentric, the sealing structure can be used soft seal, hard seal , The pressure range PN0.1-10MPa , the nominal diameter of DN40 ~ 2000mm , the material can be cast steel, stainless steel. Due to the wide range of valves used, the same valve in different situations and working conditions have different collocation.
D371X LT Butterfly Valve uses and features
LT-type butterfly valve for food, medicine, chemicals, petroleum,
electricity, metallurgy, urban construction, textile, paper and other
water supply and drainage, gas pipeline for regulating flow and
interception of the role of the media, its main features are:
1, novel design, reasonable, unique structure, light weight, quick opening and closing.
2, the operating torque is small, easy to operate, labor-saving Qiao clever.
3, can be installed in any location, convenient.
4, the seal can be replaced, reliable sealing performance, to achieve two-way seal zero leakage.
5, sealing material aging resistance, corrosion resistance, long life and other characteristics.
6, simple structure, universal interchangeability, low prices.
7, stem seal is not easy to deform to avoid the usual stem leakage. Overall supportive, stable, strong.
8, seat rubber less consumption, the potential impact of expansion is
small, easy to control the torque value within the appropriate range of
two-piece stemless pin connection, simple and compact structure,
demolition is extremely convenient.
9, the butterfly plate with automatic energy to achieve a combination
of butterfly plate and valve seat over the interference. Phenolic back
seat with non-shedding, tensile, leak-proof, easy to replace and so
on. As the seat sealing surface and the back as a whole, thereby
reducing the deformation of the valve seat.
