Hi gerhardl, thanks for your fruitful reply.
I have checked Gestra range they speak about steam traps but my application is potable water and I ask for combination air valves, my water temprature from 25-40 C degree,
what you think?

Hello All,
Please note that I have waterworks application and there are some areas approx. 10 miles length with total elevation (-)620 meters, gravity pressurized line so the working pressure there exceed 60 bars of water pressure and we would like to fix some air release valve to eleminate the...
Hello All,
I have potable water application on duty, pipe size 32 inches and this line 25 years old from ductile iron material.
Pipeline depends on gravity and there are 8 miles distances with negative elevations, the line intake from reservoir to feed the system and house connection.

Hi David,
I mentioned that application is sewage water also the pressure is 10 bars, should calculate 1 bars losses because of elevations , if you need something else, please let me know.

Hi TD2K, I am agricultural field, I have less info on calcualtion of hydraulic that is why I come to our experts, I really do not know how to calculate this formula.

By the way the surge anticipating control valve will be more quicke response than pressure relief valve, it will be opened at very less positive wave.

Hi all,
Could you please advise how I can calculate GRP pipe diameter?
I have application submersible pump for sewage water, flow rate 200 L/S, pressure is 10 bars, Pipe line length is 200 meters.
Thanks in advanc,
Baram
Thank you very much valving as I see it is flow control valve parallel with pressure control , this valve always will be in dynamic movements always so can not adjust it to mean pressure but for pilot operated pressure reducing valve we can pre-adjust the required pressure so the valve will keep...
