I would like to give you some more project info for the selection of the gear box.
We (you) are free to select any suitable gear box for the valve but is has to be economically and with rather fast delivery time as the job has to be done (completely) within app. 5 month (real challenge) with the first partial shipment (app. 100 pcs) around 6 weeks ex Thailand!! Please propose partial shipments according to your output.
The valve data is as follows: Z 011 – A DN 600 @ 16 bar with F 25 and round shaft 60mm with key way (we could do square 46mm too if better (cheaper) for you)
The torque @ 16 bar is 5,830 + 20% SF = 6,996 Nm
We are looking forward for your special and competitive offer for this project so we can do this one together.
Pls let me know if you have any questions this concerning
