MULTIFUNCTIONAL WATER CONTROL VALVE DIAPHRAGM PISTON
1 Based on the initial development of water control valves, SME has come up with the upgraded series with dual controller.
2 After installation, the valves are able to keep functional without further adjustment. They are popular in water supply systems, esp. in high-rise buildings.
3 The valves are working against the differential pressure change, as automatically regulating the pressure in both upper and lower chambers.
4 Common constructions are piston type and that with diaphragm theory, fitted for various media and pipelines.
