Discrete Proportional Valve System
Uses an intelligent combination of simple binary (ON/OFF) solenoid valves with varied port size to achieve stepped proportional control.
Two or more ON/OFF valves with differing flow coefficients are combined in a single manifold. Using selective actuation of the valves, a stepped approximation of a linear flow response is achieved. For example, a system of three valves gives 23 or eight possible flow states. The Discrete Proportional Valve can be designed to include a zero-flow state.
