Double Eccentric Butterfly Valve Introduction

The double eccentric butterfly valve offers notable cost and space savings, a broader size range, and faster operation compared to other valves. Its design reduces restriction and wear between the disc and seat, ensuring a longer cycle life and lower total cost of ownership. The two-offset design contributes to extended service life and lower torque, making it suitable for frequent operations. The Bosseal high-performance butterfly valve has successfully passed a million-cycle test.
