ZSHW Pneumatic Large Caliber Adjustment Butterfly Product Features:
1. Pneumatic butterfly valve operating torque is small, is a very small type of operating torque in all valve types, opening and closing quickly, to compressed air as the power, through piston toothbar, gear's mechanical drive valve rod, to angle stroke output of torque rotating valve plate 0 ~ 90°, you can quickly complete the opening and closing action, structure simple, small volume, light weight, small flow resistance, large flow coefficient, sealing performance good.

2.Using electric-gas valve positioner, with electric signal and compressed air as power, accept control system input 0-10mA DC or 4-20mA DC current signal, by the regulator will compress air, convert to air source pressure signal input output, change the valve plate's rotation angle (0-90° any angle), with better regulation control flow and other parameters.
3.Adopt electromagnetic switching valve, valve level relay, with AC220V or DC24V power supply voltage and compressed air to achieve rapid two-digit cutting control of conveyor media. 3.Adopt electromagnetic switching valve, valve level relay, with AC220V or DC24V power supply voltage and compressed air to achieve rapid two-digit cutting control of conveyor media.
4. Pneumatic execution mechanism adopts piston-type cylinder and curved arm conversion structure, output torque large, volume small, adopting full sealed waterproof design protection level high. Pneumatic execution mechanism adopts piston-type cylinder and curved arm conversion structure, output torque large, volume small, adopting full sealed waterproof design protection level high. Cylinder body uses mirror cylinder, no oil lubrication, friction coefficient is small, resistant to corrosion, with a super strong durability and reliability.
