ZJHB Pneumatic bellows control valve consists of pneumatic diaphragm actuator and bellows seal globe valve.Top of the bonnet from the bellows seal control valve adopts a bellows sealing structure, which could completely eliminate the potential of the medium dripping outward in the valve stem movement gap.It's appropriate for that charge of very toxic,flammable,explosive,volatile and rare rare metal medium. Additionally, pneumatic bellows seal control valves may also be used in vacuum applications.
