Water cooling system valve

Solenoid valves ensuring operations reliability

Water cooling for rock drilling equipment serves an important function as they cool down the drill and drill head as well as transport away the drill dust from the drilling hole. On rock drilling machines vibrations, water hammering and harsh environment is critical, Danfoss recommends to use EV224B solenoid valve.
