Danfoss ICM50-DN65,ICM100-150ANSI Motor operated valves Function

ICM, motor operated valves are designed for use
with the ICAD actuator with Display.
The driving force from the actuator is transferred
via a magnetic coupling (a) through the stainless
steel top housing (b) and thus eliminates
the need for a packing gland. The rotational
movement of the magnetic coupling (a) is
transferred to a spindle (c) which in turn provides
the vertical movement of the piston (d) and the
valve seat (e), to open and close the valve. The
closing force of the actuator, combined with
the the valve seat (e) and PTFE valve plate (f),
provides an effective seal to prevent leakage
across the valve port, when the valve is in the
closed position. To prevent damage to the PTFE
valve seat (e) and plate (f) from system debris, it
is recommended that a filter is installed upstream
of the valve. Please refer to page 14 for filter
sizing and application recommendations.
ICM 20 – 65:
Valve inlet pressure (P 1 ) acting on the underside
of the PTFE valve seat (e) also passes through
the hollow piston assembly (d) on to the top of
the piston (d) and balances the pressure acting
on the piston (d). Any trapped liquid across the
throttle cone (g) is allowed to equalise down
to the valve outlet without affecting the valve
performance.
ICM 100 – 150:
Function (valve)
Valve inlet pressure (P1) acting on the underside
of the PTFE valve plate (h) also passes through
the equalization hole (i) and ensures that the
servo piston (j) is pressure balanced. This will
equalize P1 and P2. During an opening operation
of the valve, the pilot piston (k) will be raised
from its valve seat inside the servo piston (j).
This allows the P2 pressure to escape through
the servo piston (j) to the outlet of the valve.
The pressure P1 will act on the underside of the
servo piston (j) and force it to open. This will
close the gap between the pilot piston (k) and
the servo piston (j) until the pressures P1 and P2
are equalized again. When there is no pressure
difference between P1 and the outlet of the valve
the pilot piston (k) is attached to the servo piston
(j) ensuring it to open up.
