Sea water presostatic control valve
Sea water presostatic control valve
(OP)
For a sea water R-22 condenser I need to find a presostatic flow control valve. There are several tahat work with fresh water, and the only one I know for sea water is about 1 1/2" inches. Too small.
I need a flow of sea water about 48 m3/hr this is about 2 1/2" or 3" diameter. The valve should close or open depending on the pressure in the condenser. I need a pressure in the R-22 water condenser of about 150 to 220 psi. The valve pressure drop shoul be about 1 Bar at maximum flow.
Does anyone know another way to control this (remember the big problem is sea water so corrosive).
I also think of several smaller valves in paralel. What do you think about this alternative ?
Regards

Thanks sterl. Metrex seems to have all the valves you can ever need.
I apreciatte HVACR2 for his sugestion, but I do not know how to apply that. I think you are confused. The PM will control the refrigerant flow and what I want to control is the sea water flow to the condenser.
