Reasonable structure, light weight, flexible operation and reliable sealing.
The sealing ring is made of stainless steel plate and non-metallic material.When the valve is closed, several ring seals are formed between the sealing pairs, which makes the sealing effect better.
The series butterfly valve adopts tri-eccentric structure, the sealing surface adopts the form of oblique push surface, the valve sealing force is formed by the compression stress transferred from the stem torque to the inclined cone surface, the reasonable design eliminates the valve plate shaft end seal surface and the valve seat process contact friction, avoids the scratch, closes more tightly, the seal is reliable, after opening the sealing surface completely disengages, protects the sealing surface, causes the valve service life to be longer.
Wide range of application, with corrosion resistance, high temperature resistance, scratch resistance, long service life and other advantages. The valve has strong applicability and can be used instead of many other valves
A precise synchronous indicating mechanism can indicate the opening and closing state of the valve in the most convenient and conspicuous position
