FC-B Series Bellows Control Valve
Overview and application
The valve applies sleeve and pressure balanced valve plug to ensure good sealing performance and allow large pressure difference. With good stability, compact structure and the sealing upper bonnet and bellows component on bellows, it can ensure no leakage of media. It is widely applied in working conditions involving poisonous and corrosive media that has high requirements on sealing in petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry and electric power industry.
