Manual WCB Butterfly Valve



Brief introduction

The body and seat of the carbon steel butterfly valve are conjoined components, and the sealing surface layer of the seat is welded with temperature-resistant and corrosion-resistant alloy materials. The multi-layer soft laminated sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, this butterfly valve has high-temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism increases to compensate for the sealing, which improves the butterfly valve. The advantages of sealing performance and extended service life. The driving modes of Shuangde butterfly valve mainly include manual, turbo, electric, pneumatic, hydraulic, etc.
