Hello everyone,
Well this time I have to find some 8-10" butterfly and check valves, made from HDPE.
Now, I saw that PVC is the most common type of material and the cheapest as well, I want to know if my requirement of HDPE valves could be replaced by PVC valves?
What would be the advantages...
Thanks for all the helpful answers, in this situation "best" would mean cheapest valve that can do the work, and "control", throttle the flow through with 10% error give or take and a delay of a few seconds.
I think this time I'll choose the globe valve.
Regards.
Well the control valve needs to have a linear behavior that's why I suggested globe valve, but maybe we could do it with pinch valve as well.
As for remote operation and data logging, it is more important to have remote control, data logging isn't a priority.
And the setpoint doesn't have to be...
We have a client that wants to install a system which does the following:
- Have a modulating control valve (for example a globe valve with a 4-20mA positioner).
- Has a flowmeter installed on the same pipe.
- Flowmeter sends the flow data to a PLC, and this PLC will send a signal to control...
Hello, I've been looking for valves which can work at high temperatures (at most 250ºC), I'm not too worried about the pressure, but valves which can resist that pressure generally don't resist that temperature, the diameter I'm looking for is 2". Thanks!
