Product description
● the reducer and gas combined use of pneumatic device is used to
open the 90 ° butterfly valve, ball valve, manual or pneumatic
drive.
Characteristic
The series of products, output torque and pneumatic device, valve
matching.
● has the advantages of small volume, light weight, reasonable
design, novel style;
● pneumatic, manual. Rotating the eccentric rod device is 90 °, the
handle is located above the position, manual operation. The handle
is located in the lower position, pneumatic operation.
● worm connected hole two keyway are separated by 90 degrees so
that the user to choose the device with the valve body relative
position.
● products with special grease, and valve assembly, whole sealing,
dustproof, waterproof, protection class IP65.
Instructions for use
● reducer and the bottom surface of the valve is connected, on the
support surface is connected with the cylinder, valve shaft through
a wormhole, the valve shaft end square matched with the cylinder
hole; (process: pneumatic cylinder to drive the valve shaft,
With the transfer gear. Manual, engaged with the worm wheel, driven
by the rotation of the valve shaft, cylinder piston also
follow-up).
● the handle is located above the position, manual operation, not
pneumatic. Pull out the limit pin, rotate the handle clockwise to
the lower position. The worm, worm disengage, pneumatic.
● handle at the lower position, pneumatic operation, no manual.
Pull out the limit pin, counterclockwise rotation of the handle to
the top position. The worm, worm gear, manual. Pneumatic switch
manual process
Top teeth phenomenon, a rotation handwheel, ensure that the worm
wheel and the worm gear mesh correctly, you can manually.
● pneumatic drive and manual cannot.
Product characteristics:
1 small volume, light weight, reasonable design, novel style;
2 series of products, output torque and pneumatic device, various
valves.
3 worm connected holes made an octagonal structure or special money
with you to custom angle connection or key connection so that users
can choose according to the relative position of the same body
device.
