                                                                                                                    N° 2 fori M4
In case of fluid temperatures higher than the maximum allowed, connect the
pressure switch to the pipe by inserting a metallic spiral between the pressure
switch and the pipe to facilitate heat dispersion.
Possibility of mounting on metallic clamp, exept for the waterproof casing versions.                    35 mm




OPERATION
When pressure increases: 1-2 opens, 1-4 closes.
In the pressure switch with blocking and manual reset at maximum pressure, the reset takes place when the pressure is below
the value set on differential.
