Pneumatic pneumatic piston actuator flange butterfly valve from the Angle of stroke and butterfly Industrial Valves body composition, using three-dimensional eccentric principle design, make the space of the sealing surface movement to achieve ideal, sealing surface without friction, without interference with each other, together with sealing material is properly selected, so that the butterfly valve sealing, corrosion resistance, high temperature resistance and wear resistance are the reliable guarantee. Pneumatic flange butterfly valve small open torque, flexible, convenient and saving energy. Pneumatic flange butterfly valve operating torque is small, is the smallest of all valve operating torque in class a, rapid opening and closing, powered by compressed air, through the piston rack, gear mechanical transmission of the valve stem, to Angle the itinerary of the output torque rotating disc 0 ~ 90 & deg; , the completion of the opening and closing action can be quickly, simple structure, small volume, light weight, small flow resistance, flow coefficient, sealed performance is good. The adjusting range is big. Is the instrument automation control system of execution unit; The electric - pneumatic flange butterfly Industrial Valves Gas valve positioner, powered by electrical and compressed air, accept input 0 - control system Madc or 4-10 20 madc current signal, the controller will be compressed air, air pressure is converted to the signal input and output, change the rotation Angle of valve plate ( 0 - 90° Arbitrary Angle) , and has good adjusting parameters such as control flow. Flange butterfly valve USES solenoid directional valve, pneumatic Industrial Valves position device, back to AC220V or DC24V power supply voltage and compressed air as the power, to achieve fast two to cut off the control of fluid medium. Pneumatic actuators using piston cylinder and crank arm structure, output torque, small volume, adopt full sealed waterproof design protection grade is high. Cylinder block USES the mirror cylinder, oil free, small friction coefficient, corrosion resistance, with super durability and reliability. All drive bearing adopts boundary self-lubricating bearing without oil lubrication, ensure that the shaft friction losses.
is emerging as one of the most popular flow control valve, moving beyond its os&y valve benefits, with conclusive scientific evidence suggesting the positive role play in resilient valve.
