Pagination or Media Count:
An E-R hydraulic control valve that has two or more surfaces that can be moved relatively to one another to adjust a flow orifice size while maintaining a control voltage gradient across the E-R fluid and to seat one surface against the other to shut off fluid flow. Combining movable mechanical fluid flow clements with E-R fluid control allows initial tuning of the valve to a particular application by mechanical restriction of an orifice, and E-R operating control of the fluid. Seating the mechanical surfaces provides a fail-safe shut-down mode.
