On-off valves, electric HEE
Classic
The Festo HEE electrically operated on-off valves extend the HE range with electrical actuation. With 33 variants in port sizes G 1/8 to G 1 and supply voltage options of 24 VDC, 110 VAC and 230 VAC, compressed air circuits can be switched in remotely and automatically. The throttled pressure build-up on switch-on is retained compared to the manual HE.
Voltage variants 24 V / 110 V / 230 V - matching version for each control voltage without external converter
Port sizes G 1/8 to G 1 - MINI, MIDI and MAXI frame sizes covered
Throttled pressure build-up - prevents pressure peaks on electrical switch-on, protects actuators
PLC-compatible - electrical actuation integrable into higher-level controls and safety circuits
Classic system design - combinable with LF, LR, LOE and FRZ of the Classic range
