Temperature setting range
OB-1
| Temperature setting range (° С) | Withstanding temperature (° C) | |
| For liquid | For air | |
| 40-60 | 40-60 | 70 |
| 50-70 | 50-70 | 80 |
| 60-80 | 60-80 | 90 |
| 80-100 | 80-100 | 110 |
| 100-120 | 100-120 | 130 |
The term withstand temperature refers to the maximum temperature at which the bellows can withstand internal pressure.
Variants with a temperature control range of 30 ° C are available (only OB-1).

The term withstand temperature refers to the maximum temperature at which the bellows can withstand internal pressure.
- Easy installation thanks to the split threaded sleeve.
- Temperature adjustment is carried out using a knob without the need for additional tools.
- The double valve design allows higher flow rates than a single valve.
- Exceptional precision thanks to a special stem packing that influences the opening / closing of the valve.
- The OB-1G model provides excellent thermal stability thanks to the external pressure bellows.

How to use a chart
When selecting the nominal size of the temperature controller at inlet pressure (P1), outlet pressure (P2) and steam flow rates of 0.3 MPa, 0.25 MPa and 60 kg / h, respectively, first find the point of intersection (a) of the pressure lines on inlet 0.3 MPa and outlet pressure 0.25 MPa. From this point (a) draw a line down to the intersection with the line corresponding to the flow rate of 60 kg / h - the point of intersection (b). Since this intersection point (b) lies between the nominal sizes 15A or 20A and 25A, select the larger one, 25A.
* The flow chart is for reference.
