Pressure regulators

Note:   The banjo to couple with the valve have to be orderd 

separately (R35 - RT28 - C23 - 025)

When installed in a pneumatic circuit, the pressure control sets the 
workingpressure of all the connected components.
The pressure adjustment will be thereby kept steady for a long 
time. 
It can also be used as an economizer when connected 
between the valve and the cylinder to operate. 
Pressure is being saved and rod speed decreased in the desired 
direction. A big energy saving is this way obtained.

Series of adjustable pressure switches used in pneumatics to 
check the min. or max. pressure of compressed air into a control 
or a feeding circuit of a machine.
These pressure switches have been equipped with N.O./N.C. 
contact able to bear 0,5A electric load at 250V.
It is advisable to fix the pressure switch vertically on the line to 
be checked to avoid that any impurity or condense inside the 
inlet could affect the correct working.
By means of the adjusting screw it is possible to reset the 
response value but by taking away the cap.

Throttle fitting

4.83.56

This fitting houses a cartridge with a calibrated orifice.
The orifice diameter causes a flow throttling thereby allowing the 
desired flow (see our Chart 1).
The throttle fittings are mostly used when the user knows the exact 
cylinder speed hand when no further settings of the cylinder
are requested.
The major advantage is that no undesired tamperings can occur 
and in case of vibrations the flow setting will remain stable.
