70E High Performace Double Offset Butterfly Valve


Product Description

The butterfly valve applies double eccentric structure. Its valve spindles deviate from valve body construction center, and its disc plate applies circular sealing face structure, henceforth, the disc plate is rapidly released from sealing seat as opening to reduce the friction of the sealing face, the disc plate provides excellent sealing performance as closing. The self-centering sealing seat combines the unique compensation sealing structure of valve seat, enables the valve seat sealing to be effectively compensated and reduce the friction of starting and closing, and to greatly reduce the operation force of the valve and effectively increase the control precision of the butterfly valve. With reliable stability and long service life, it is applicable for the control and shutoff of common corrosive gas and liquid medium.
