Product Details
Overview of imported pneumatic bellows cage double seated regulating valve:
The bellows cage double seated regulating valve is a pressure-balanced regulating valve. The valve body has a compact structure, the fluid passage is S-streamlined, the pressure loss is small, the flow is large, and the adjustable range is wide. The upper valve cover is sealed with a wave tube pattern. The structure can completely eliminate the possibility of process medium leaking out from the valve stem movement gap, which is one of the salient features of the bellows sealing valve. Due to the deformability and outstanding aging resistance of the bellows element itself, this regulating valve is completely Overcome the weaknesses of packing aging and temperature difference sensitivity commonly found in packing seal valves. Second, the bellows-filling double sealing structure is used for better safety and reliability. Therefore, it is extremely rare in special media such as highly toxic, highly corrosive, and radioactive. Is widely used in automatic control systems.
The control valve is equipped with a multi-spring type diaphragm actuator, which has a compact structure and a large output force.
