As a single unit and in combination with our available directional control valves, the pressure switch can take on monitoring and protection tasks in water and oil hydraulics as well as in neumatics up to a max. pressure of 320 bar. A second version type series can be used in gas plant up to 100 bar.
Function
As a single unit and in combination with our available directional control valves, the pressure switch can take on monitoring and protection tasks in water and oil hydraulics as well as in pneumatics up to a max. pressure of 320 bar. A second version type series can be used in gas plant up to 100 bar.
Special feature
The switching element responds without delay. It can be driven hydraulically or pneumatically at different pressure levels. Within each pressure level it can be adjusted continuously and finely. A possible lead-seal protects against any unauthorized tampering with the adjustment. The pilot-control valve has a lockable manual operation. It can also be provided with a locking device so that it cannot be switched manually by unauthorized persons, and also cannot be switched back into its basic position even after responding to and being triggered by the switching element. On request the pressure switches can also be fitted with manual vent levers to allow excess pressure or pressure drop conditions to be simulated for test purposes. A further separate and externally located manual adjustment provides for any operator to switch back the pressure switch after this has responded and once operating pressure has again been reached. There is a DVGW reg. No. for the pressure switch in combination with a use as a high pressure safety shut off device.
