  • 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-5).
  • Low leakage single seat valve.
  • Smaller and lighter than other temperature controls.
  • No additional adjustment tool is required, the regulator is equipped with a knob for setting the temperature.
  • Exceptional precision thanks to a special stem packing that influences the opening / closing of the valve.
  • Due to the presence of a split threaded coupling, installation on the pipeline is facilitated.

How to use a chart

If the inlet pressure (P1) is 0.4 MPa, the outlet pressure (P2) is 0.3 MPa, the flow rate is 80 kg / h, find the intersection point (a) of the lines P1 = 0.4 MPa and P2 = 0, 3 MPa. From this point (a) draw a line down to the intersection with the line corresponding to the flow rate of 80 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.
