Multi-layerhard seal gas butterfly valve has reasonable structure, small volume, lightweight, small opening torque, light weight, flexible operation, flow characteristics tend to straight line, superior regulation performance,reliable sealing, and wide range of applicable working conditions. After long-term use verification, excellent product performance, well received byusers
Multi-layer hard seal gas butterfly valve characteristics;
1.Reasonable structure, light weight, flexible operation and reliable sealing.
2.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.
3.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 conesurface, 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 servicelife to be longer.
4. 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
5.A precise synchronous indicating mechanism can indicate the opening and closing state of the valve in the most convenient and conspicuous position
Multi-layerhard seal gas butterfly valve is eccentric metal seal structure, sealing formis metal to metal seal, can replace metal seal ring to metal seal, andstainless steel plate and graphite composite plate seal ring to metal seal.Hard sealed butterfly valve in addition to the driving form of electric:manual, worm rod drive, pneumatic and so on.
