Ra 8uin.(0.2 um) Product DescriptionDefinitionPneumatic bellow valve is a kind of control valve widely used in the field of industrial automation, which is known for its high precision, high stability and high reliability.The bellow valve regulates the flow rate of the medium by adjusting the opening of the valve.Working theoryThe working principle of the pneumatic bellows valve is based on the pneumatic signal received by the actuator to control the movement of the bellows, so as to change the flow area of the valve and realize the adjustment of the medium flow. When the pneumatic signal is activated, the bellows is pushed to move, so as to adjust the flow area and achieve the purpose of changing the flow rate. When the pneumatic signal disappears, the flow area returns to its initial state, ensuring precise control of the medium.FeaturesMetal-to-metal gasket seal ensures no leakage.Precision-constructed bellows for reliability.Non-rotating stem tip increases cycle life.Manual and pneumatic actuator options.Pneumatic actuator rotates 360° for easy air line connection.Panel and bottom mounting available.Normally closed pneumatic valves can be supplied with indicating switches.FAQFAQ1.
