Non Return Valves and Water Differential Pressure Switches采购内容
We are looking for the Non Return Valves and the Water Differential Pressure Switches to fit into our project. The units that we will be assembling are to be fitted into the main water supply for residential use; therefore they must be approved for drinking water. (Stainless steel or brass) The inlet pressure varies for different sites, but the water differential pressure will stay constant. If the inlet pressure is 100 PSI and the 1inch non return valve has a stronger spring fitted to hold 5 PSI when the outlet pressure drops below 96 PSI the water differential pressure switch would close sending a signal to the 1 inch latching solenoid to close. I have seen these manufactured as one unit but only in small sizes which will not deliver the flow of water required. If your company can supply these items we would require a sample of each to fit into the pipe work for testing purposes, is this possible and at what cost. 联系方式Co:Mudgeeraba Plumbing Add:16 Straire Drive, Robina, Australia Tel:61-07-55755234 Fax:61-07-55307355 Email:sbmack@bigpond.com 联系人：S H MacKenzie国家：Australia产品类别机械五金sbmack@bigpond.com
