The ICM motorized valve is comprised of up to 4
components:
• the valve body – often referred to as the ICV body
because it is used for ICM motor valves, ICS pilot
operated valves and ICLX solenoid valves.
• the function module – the ow regulating part of
the valve
• the top cover – on the ICM 20 through 65, the
function module and top cover are one part
• the ICAD motor actuator – the “brains” of the
valve

ICM/ICAD overview The combinations of valve and actuator are as follows:
* ICAD 600, 900 and 1200 were discontinued at the end of 2014. ICAD 600A is a direct replacement of ICAD 600 and ICAD 1200A is a
direct replacement of ICAD 900 or ICAD 1200.
