The term withstand temperature refers to the maximum temperature at which the bellows can withstand internal pressure.
- Due to the presence of a split threaded coupling, installation on the pipeline is facilitated.
- No additional adjustment tool is required, the regulator is equipped with a knob for setting the temperature.
- Thanks to the double valve, the operating flow range of these models is wider.
- Exceptional precision thanks to a special stem packing that influences the opening / closing of the valve.
- The OB-3G model has excellent thermal stability due to the external pressure bellows.

How to use a chart
If the inlet pressure is 0.3 MPa, the outlet pressure is 0.15 MPa, the flow rate is 9 m3 / h, find the intersection point (a) of the differential pressure lines (∆Р = 0.15 MPa) (0.3 MPa - 0.15 MPa) and a flow rate of 9 m3 / h. Since this intersection point (a) lies between dimensions 32A and 40A, choose the larger of the two, 40A.
