Inquiry (采购产品): differential pressure control valves In a large district cooling application, we are interested to install differential pressure control valves at each energy transfer station to maintain flow and minimise the effect on individual branches when other branches close and open. The line sizes in branches are 300 dia to 450 dia with flow rates of 1700 gpm to 2200 gpm. Do you deal with such valves. The valves are expected to be self balancing. **** Hidden Message ***** Ganesh Krishnamurthy ARE Company: Halcrow Title: Principal Engineer Phone: +971-50-3580701 E-mail: ganeshk@halcrow.com **** Hidden Message ***** ganeshk@halcrow.com
