Flange type pneumatic soft sealing butterfly valve by eccentric rotary pneumatic piston actuator and valve body composition, the design principle of three-dimensional space trajectory eccentric, the sealing surface of the sealing surface to achieve the ideal, no friction, no interference between each other, and the sealing material selection properly, so that the valve sealing, corrosion resistance resistance, high temperature resistance and wear resistance has been a reliable guarantee.

First, Pneumatic Flange Soft Sealing Eccentric Butterfly Valve Product Characteristics

1, The operating torque, operation torque is a minimum of all valves, open and close rapidly, powered by compressed air through the piston rack, mechanical drive rod gear, a rotary output torque to rotate the valve plate of 0~90 degrees, will be able to complete the opening and closing fast, simple structure, small volume, light weight, small flow resistance, flow coefficient, good sealing performance. Large range of adjustment. It is the execution unit of the instrument in the automatic control system.

2, The electric - gas valve positioner, the electrical signal and compressed air as power control system, accept input 0-10mADC or 4-20mADC current signal by the regulator will be converted into the compressed air, the air pressure signal input and output, changing the angle of rotation of the valve plate (0-90 degrees, with arbitrary angle) control flow parameters such as well the.

3, Using electromagnetic reversing valve, valve position return device, with AC220V or DC24V power supply voltage and compressed air as power, to achieve rapid two bit cut-off control of fluid medium.

4, The actuator adopts piston type cylinder and crank arm transfer structure, the output torque is large, the volume is small, the use of full sealed waterproof design, high protection level. Cylinder body adopts mirror cylinder, no oil lubrication, small friction coefficient, corrosion resistance, super durability and reliability. All drive bearings adopt boundary self lubrication bearings without oil lubrication to ensure that the drive shaft does not lose friction.
