Posiflow Proportional Solenoid Valves ASCO Posiflow Valves are 2 way direct acting, and pilot operated fail closed Proportional Solenoid Valves in which flow is directly related to the electrical input. As input increases, so does the flow, and vice versa. Flow can be adjusted from 0% to 100% of the valves capacity to meet yourspecific application needs. Control achieved by applying straight voltage between 0 and 24 VDC via potentiometer or other variable power supply. Flow rate can also be regulated by a range of electrical inputs (sensors, transmitters, PLC, etc.) via an ASCO Electronic Control Unit or similar circuit. Suitable for use in air/gas, low vacuum service, as well as to precisely control flow of water.
