By coating the disc with EPDM rubber (elastic body), the restitutive power of this wafer style butterfly valve (HPBO-W1) between the valve’s body and rubber helps to maintain air tightness. A disc rotates 90 degrees to control the fluid in motion, maintaining high responsiveness under operations with low friction loss and low torque.
Fast operation is possible thanks to simplified opening/closing processes. This valve is applicable to control
