American standard adjustment application and structure characteristics of pneumatic valve

American standard butterfly pneumatic valve is widely used in low pressure, medium pressure and high pressure, iron and steel metallurgy, petroleum, chemical, electric power and other industrial piping for truncated or adjust medium flux. American standard butterfly pneumatic valve adopts three-dimensional eccentric oblique cone pneumatic valve seat seal, butterfly plate laminated seal USES the new type of metal and elastic material, embedded on the butterfly plate in accordance with the pneumatic valve seat. Using pressure tight seal of butter fly-hoard oscillation, the sealing surface friction resistance is small, so the shut tight function when it is closed, the sealing is reliable, open to ensure sealing surface completely out of contact, to ensure the sealing surface is not damaged.
American standard butterfly pneumatic valve structure ruled out other types of butterfly valve open instead of the defect of sealing, and under the Gao Shu can normal use, overcome the other types of pneumatic valve used in high temperature due to thermal expansion easy leakage faults. The pneumatic valve adjusting farming tools use medium requirements, choose different sealing surface material, to ensure the sealing surface wear resistance, corrosion resistance, long service life. American standard butterfly pneumatic valve structural characteristics of the specific as follows:
the unique design of three-way eccentricity between the sealing surface friction drive, prolong the service life of pneumatic valve.
(2) generated by the torque of the resilient seal;
3. Clever wedge design make the pneumatic valve has closed more and more tightly automatic sealing function of seal face with compensatory, zero leakage between;
4. Small volume, light weight, light operation, easy to install;
(5) according to user requirements with pneumatic, electric devices, meet the needs of the remote control and programmed control.
6 replacement parts material can be applied to all kinds of medium, and can be carried out lining anticorrosion ( F, GXPP, PO, etc. ) ；
7) continuous structure diversification, clamp, flange, butt welding.
