2 EDM TYPICAL PERFORMANCE SPECIFICATIONS DESCRIPTION These proportional directional control valves are -way, direct operated, spring centered, sliding spool valves. They can be used to control flow direction and rate. Directional control is achieved by solenoid selection; flow rate is a function of the input signal amplitude. This model features spool position feedback via an LVDT for improved valve performance. If electrical power is lost, the valve spool will return to center position. SPOOL METERG Combination metering spools (code "C") meter oil into and out of the hydraulic actuator. These spools provide excellent control in most applications and are highly recommended where deceleration control of a hydraulic motor is required or in velocity feedback applications. Combination metering spools can also be used with a pressure-compensated module to provide proportional pressure compensated flow. The code C spool is not recommended for cylinders with ratios of./ or greater. Meter-in spools (code "I") meter oil into the actuator. This spool can be used in applications where the actuator is always working against a positive (resistive) load. Meter-in spools can be used with a pressure compensated module. Meter-out spools (code "O") meter flow out of the actuator. These spools are commonly used in applications with "run away" loads such as over-center loads. Meter-out spools are also used with high ratio cylinders. It is important to properly size a proportional valve to achieve good resolution. A common mistake when specifying proportional valves is selecting too high a rated flow capacity spool (low P). The result may be poor control of the actuator, particularly with respect to velocity and resolution. Ideal valve size is usually one that provides just enough maximum flow capability to achieve the desired velocity. Consult with Continental about special metering characteristics: unequal-metering, step metering, other nominal flows and other spool configurations. Use caution when applying a separate internally-drained pressure control valve between the actuator and the proportional valve. Back pressure created by meter-out or combination metering proportional valves can add to the spring load of the pressure control valve, resulting in a change of the control pressure level.
