Product Overview

The M3FB...LX... valve and the ZM... or ZM.../A terminal housing must be ordered
separately.
See data sheet N4591 for information on the ZM... terminal housing.
See sheet N4000 for a summary of refrigerant valves.
When placing an order, please specify the quantity, product description and type code.
Example :
1 control valve M3FB15LX/A
and
1 terminal housing ZM101/A
The armature or magnetic core is designed as a floating component within the pressure
system, so that no external shaft gland is required. The leakage losses common with
moving parts are thus avoided. The valve cross-section allows for easy flow whether the
valve is fully or only partially open. This reduces pressure losses and ensures quiet
operation.
The valves are fitted with extended female solder unions, making pipe connection easy.
The control signal is converted in the ZM.../A terminal housing into a phase cut signal,
which generates a magnetic field in the coil. This causes the only moving part, the
armature, to change its position in accordance with the interacting forces (magnetic
field, counter-spring, hydraulics etc.). The armature responds rapidly to any change in
signal, transferring the corresponding movement directly to the control disc, enabling
fast changes in load to be corrected quickly and accurately.
The force of the counter-spring closes the valve automatically (control path ports 1 –> 3)
if the power is switched off or fails.
