OPERATING PRINCIPLE :
The regulation takes place by means of a spring force by moving the diaphragm and the stem against the gas pressure flowing through the regulator, below the diaphragm assembly.The outlet pressure can be varied by means of adjusting the spring force.
The design offers constant set pressure(±5% of the set point)irrespective of change in inlet pressure and inlet flow.
Also available with external impulse line with vibration damping valve to achieve greater accuracy in outlet pressure. |
