Duplomatic proportional directional control valves comprise of a normal control valve spool actuated in both directions by solenoids. The solenoids are proportional in that they will drive the spools to a position dependent on the electrical signal received by the solenoid. Typical applications are when control is needed to electronically vary flow and hence actuator speed.

Temperature
Oil temperature should be between +30ºC & +60ºC during normal operation. Oil life is greatly reduced if temperature exceeds 60ºC. As a general rule, oil life is halved for each 8ºC temperature exceeds 60ºC.
Filtering
It is necessary to keep the level of contamination within a hydraulic system at an acceptable level to ensure trouble free operation. Filtration should always be specified at a level that protects the most sensitive item or component in the system. |
