Cast Iron Declutchable Gearbox With Hand Wheel Manual Override For Pneumatic Rotary Valve Actuators
Veson VSM series Manual Override Declutchable Gearboxes ranging from 300Nm to 3200Nm comes with ISO Actuator and Valve mountings, offer reliable and simple manual positioning of valves, and other quarter-turn devices where manual override is required on pneumatic or hydraulic rotary actuators.
All our TCMO series are of rugged design, lightweight and modular to provide the most efficient and cost-effective solution for a comprehensive range of manual override options. Our Gearboxes are external epoxy painted which provides superior resistance for the rigorous environment. The self-locking worm gear is designed to provide safe and easy operation and long life.
● the reducer and gas combined use of pneumatic device is used to open the 90 ° butterfly valve, ball valve, manual or pneumatic drive.
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.
