Solenoid valves play an important role within refrigeration and air conditioning
systems, controlling the flow of refrigerants. Though their base function –
turning the refrigerant flow on and off – is quite simple, this function is key to
ensuring system performance.
Understanding how solenoid valves work increases the likelihood that contractors
will install, remove and reinstall valves correctly, ensuring optimum system
performance and protection.
