D&D Ricambi Srl: the leader on supply of hydraulic components and systems
hydraulic components for construction, earthmoving, agricultural and industrial machinery
 
 
Pressure switches K4
 
 
  “K4” adjustable pressure switches permit opening or closing of an electric
circuit upon reaching predetermined pressure value . The preset pressure is
found by rotating the external screw located at the centre of the instrument
clockwise to increase and vice-versa to decrease the pressure set point value.
Mechanical stops protect both the spring and the micro-switch. from over
pressurization. The main characteristic of this series is that this miniature
pressure switch can be totally dismantled.
 
 
 
Pressure switches F4
 
 
  “F4” adjustable pressure switches allow a micro-switch commutation once a
preset pressure value is reached. Working on the central screw in the P2 execution or intercepting the regulator dowel put inside the instrument using a 2mm hexagonal screw, rotating the operating point in hourly sense to increase and vice-versa to decrease. Mechanical stops protect both the spring and the micro-switch from over pressurization.
 
 
 
Pressure switches F3
 
 
  “F3” adjustable pressure switches allow the commutation of a microswitch with exchange contacts once a preset pressure value is reached.
The preset pressure regulation is effected on the regulation knob inside the instrument and interceptable through a 2mm hexagonal key.
 
 
 
Pressure switches F3S
 
 
  “F3S” adjustable pressure switches allow the commutation of a microswitch
with exchange contacts once a preset pressure value is reached. The preset pressure regulation is effected on the regulation knob inside the instrument and interceptable through a 2mm hexagonal key.
The “F3S” execution is provided with a bigger diameter membrane that allows an excellent working operation at low pressure.
 
 
 
Pressure switches KR6
 
 
  “K6” and “KR6” adjustable electro-mechanical pressure switch, with exchange contacts, are
suitable for application where is not necessary to modify frequently the operating point. The regulation screw, interceptable with a 2mm hexagonal key in the executions “KR6” and
“K6/M3”, is situated inside the instrument, protected by an upper cap or a connector against accidental manumissions. Concerning the execution “K6/M12”, the operating point can be pre-settled in factory, or in alternative the Customer can adjust the value removing the four screws on the top of the instrument.
 
 
 
Pressure switches K7
 
 
  “K7” adjustable pressure switches allow the commutation of a micro-switch with exchange contact. The preset pressure is adjustable through a regulated screw put inside the instrument and protected by an external closure plug. Of compact and economical construction, the “K7” pressure switch is suitable for systems not requiring a constant alteration of the operating point, conversely, the possibility to block the protection plug can avoid unwanted or unintentional changes of the same value. Mechanical stops protect both the spring and the microswitch from over pressurization
 
 
 
Pressure switches K9
 
 
  “K9” adjustable pressure switches activate a microswitch once a preset pressure value is reached. The preset pressure is set by rotating the external nut clockwise to increase and vice-versa to decrease the value. The nut is supply with a locking device to stop the instrument once the pressure value is reached Mechanical stops protect both the spring and the microswitch from over pressurization.
 
 
 
Pressure switches F5
 
 
  “F5” pressure switches activate a microswitch once a preset pressure value is reached. The preset pressure is set by rotating the internal screw located at the center of the instrument. The internal screw is accessible by removal of the protection plug, clockwise to increase and vice-versa to decrease the value. The nut can be located when the set pressure is reached. Mechanical stops protect both the spring and microswitch from over pressurization. Of compact and economical construction, it is suitable for system not requiring a constant alteration of the operating set, conversely, the possibility to block the protection plug can avoid unwanted or unintentional changes of the same value.
 
 
 
Pressure switches K9-ATEX
 
 
  This pressure switch thanks to a special micro switch allow to combine the mechanical features of K9 standard with the ATEX II 2G EEX d II C T6 certification.
 
 
 
Pressure switches K5
 
 
  “K5” adjustable pressure switches activate a microswitch once preset value is reached. The pressure is set by rotating a graduated knob or, for the economical version, by a setscrew located on top of the unit. Both systems are supplied with a device permits locking the desired set pressure. Mechanical stops protect both the spring and the microswitch from over pressurization.
 
 
Pressure switches K51
 
 
  “K51” adjustable pressure switches activate a microswitch once preset value is reached. The pressure is set by rotating a regulation knob or, for the economical version, by a setscrew located on top of the unit. Both systems are supplied with a device permits locking the desired set pressure.
Mechanical stops protect both the spring and the microswitch from over pressurization.
