- If the ambient temperature is above the set temperature or below 40 ° C, use OB-2G (with external pressure bellows).
- For applications with pressures over 0.5 MPa, it is recommended to use a model with stainless steel control parts.
- Available with capillary tube up to 5 m.
- Available with maximum temperature. (Valve mechanism and seat materials and bellows are different from the standard model.)
- Available with sleeve (SUS304 or PTFE cap) for fluid.
Temperature setting range
OB-2
| Setting range temp. (° C) | Withstanding temperature (° C) | |
| For liquid | For air | |
| 40-60 | 40-60 | 70 |
| 50-70 | 50-70 | 80 |

| 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.
- Options with a temperature control range of 30 ° C are available (only OB-2).
OB-2G

| 80-100 | 80-100 | 130 |
The term withstand temperature refers to the maximum temperature at which the bellows can withstand internal pressure.
- 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 due to special stem packing which influences the opening and closing of the valve.
- The OB-2G model provides excellent thermal stability thanks to the external pressure bellows.

The OB-2G model is available in sizes up to 125A.
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.
