American Standard Butterfly Valve

American standard butterfly valve designed by Dazhong Valve Group, the valve adopts three-dimensional eccentric inclined conical valve seat sealing pair, and the butterfly plate seal is made of new metal sheet and elastic material laminated, and is embedded in the butterfly plate and matched with the valve seat. The structure of the butterfly valve eliminates the disadvantage that other types of butterfly valves cannot be sealed due to over-opening, and its performance has been at the advanced level at home and abroad.

• This series of butterfly valves is a new generation of high-performance products developed by our company's engineers and technicians. Its performance has reached the advanced level at home and abroad. It is widely used in low pressure, medium pressure, high pressure, steel, metallurgy, petroleum, chemical, It is used to cut off or adjust the flow of medium on industrial pipelines such as electric power.

• The valve adopts a three-dimensional eccentric inclined conical valve seat sealing pair, and the disc seal is made of a new type of metal sheet and elastic material laminated, which is embedded in the disc and matched with the valve seat.

• Using the butterfly plate to rotate and press the seal, so the friction resistance of the sealing surface is small, and it has the function of closing and tightening when closing, so that the sealing performance is reliable, and the opening ensures that the sealing surface is completely out of contact, ensuring that the sealing surface is not damaged.

• The structure of this butterfly valve eliminates the disadvantage that other types of butterfly valves cannot be sealed due to over-opening, and can be used normally at high temperatures, overcoming the shortcomings of other types of valves that are easy to leak due to thermal expansion when used at high temperatures.

• The butterfly valve selects different sealing surface materials according to the requirements of the medium used to ensure the sealing surface wear resistance, erosion resistance and long service life.
