Double Eccentric Butterfly Valve Introduction

Compared to other valve types, it’s obviously cost and space saving and have bigger size range, the operation is faster and there is less restriction and wear between disc and seat sealing surface. It will ensure longer cycling life and reduce total cost of ownership. 
With 2 offsets the valve is with longer working life and lower torque and is suitable for frequent operation service, Bosseal high performance butterfly valve have passed a million cycling test.
