Pneumatic flange eccentric soft seal butterfly valve produced and sold by Baigang valve group is composed
of angular stroke pneumatic piston actuator and butterfly valve body.
It adopts three-dimensional eccentric principle to design so that the
space trajectory of the sealing surface is idealized. There is no
friction and no interference between the sealing surfaces. Coupled with
the proper choice of sealing material, so that the butterfly valve
sealing, corrosion resistance, high temperature resistance and wear
resistance has been a reliable guarantee.
D643H/F Pneumatic Flanged Eccentric Soft Seal Butterfly ValveFeatures
1, the operating torque is small, all kinds of operating torque in a
valve of the smallest, quick opening and closing to compressed air as
the driving force through the piston rack and pinion gear mechanical
transmission stem , The torque output by the angular stroke of the
rotary valve plate 0 ~ 90 °, you can quickly complete the opening and
closing movements, simple structure, small size, light weight, small
flow resistance, flow coefficient, good sealing performance. Large
adjustment range. Is the automation control system instrumentation
unit.
2, the use of electric - gas valve positioner to electrical signals
and compressed air as the driving force to accept the control system
input 0-10mADC or 4-20mADC current signal from the regulator will be
compressed air into gas pressure signal input and output, Change the
valve plate rotation angle (0-90 ° any angle), with better regulation of
control flow and other parameters.
3, the use of electromagnetic valve, valve position back to the device
to AC220V or DC24V power supply voltage and compressed air as the
driving force to achieve fluid medium fast two-position control.
4, the implementing agencies using piston cylinder and crank
conversion structure, the output torque, small size, the use of fully
sealed waterproof design high degree of protection. Cylinder body with
mirror cylinder, no oil lubrication, small friction coefficient,
corrosion resistance, with superior durability and reliability. All
drive bearings are self-lubricating bearings with no oil lubrication to
ensure that the drive shaft is not worn.
