Hanging butterfly valve Electric butterfly valve material and noise prevention
(1) The shape can be freely determined, and the hardness of components can be controlled by adjusting the composition to meet the requirements of stiffness and strength in all directions.
(2) Large internal friction, good damping effect, favorable for cross resonance area, and suppression of high-frequency vibration and noise.
(3) The elastic modulus is far less than the elastic modulus of metal, which can produce large elastic deformation.
(4) Small quality, easy installation and disassembly.
