HCBW Pneumatic Cage-Type Double-Seat Bellows Sealed Control Valve
HCBW bellows sealed cage-type double-seat control valve is a pressure-balanced control valve. It features a compact valve body structure with an S-shaped fluid channel, which results in small pressure drop loss, large flow rate, and a wide adjustable range. The upper valve bonnet adopts a bellows sealing structure, which can completely eliminate the possibility of process medium leaking out from the valve stem movement gap—this is one of the significant characteristics of bellows sealed valves. Due to the deformability and excellent anti-aging property of the bellows element itself, this type of control valve completely overcomes the common weaknesses of packing-sealed valves, such as packing aging and temperature difference sensitivity. Secondly, the adoption of a bellows-packing double sealing structure ensures better safety and reliability. Therefore, it is widely used in automatic control systems for rare and special media such as highly toxic, strongly corrosive, and radioactive substances.
The control valve is equipped with a multi-spring diaphragm actuator, which has a compact structure and large output force.
