意大利FOX壓力開關(guān)F4/K4- 蘇州德魯夫一級代理

“F4”  adjustable pressure switches allow a micro-switch commutation once a preset pressure value is
reached. The set point is adjusted working on the
central screw (P3 execution) or intercepting the
regulation dowel situated inside the instrument, using
a 2mm hexagonal key (M2 and M3). Rotating clockwise
the set point is increased and vice-versa is decreased.
Mechanical stops protect both the spring and the
micro-switch from over pressurization
