Earth wire

Hi. Changing motorised valve on heating system. Old danfoss hpa2 valve has only 4 wires. New valve has an earth wire. Can I just connect this earth wire to the existing 2 earths from the mains and thermostat that are in the junction box. They’re 2.5 wire. One from valve isn’t

Yes all earths should be connected together.
