Proportional directional valves meter hydraulic flow in response to an electrical command. Select an execution by its spool symbol, nominal flow and stated pressure differential, control interface and electrical supply. Position feedback and integrated electronics are execution-specific features.
Compare pressure limits for each port and the manufacturer’s fluid, installation and operating conditions. De-energized behavior depends on the spool and electronics; a fail-safe position does not imply leakage-free isolation.
