ICS Pilot-Operated Servo Valve
Brand: Danfoss
The valve comprises three main components: valve body, function module and top cover.
ICS pilot-operated servo valves are pilot operated valves for regulating pressure, temperature and ON/OFF function in refrigeration systems.
ICS valves are designed for low and high-pressure refrigerants. ICS valves can be used on the high and low-pressure sides, in wet and dry suction lines and in liquid lines without phase change (i.e. where no expansion takes place in the valve).
The function of ICS valves is dependent on the pilot pressure applied from either a pilot valve or external pilot pressure source.
ICS 1 pilot has one pilot pressure connection and ICS 3 pilot has three pilot pressure connections.
