RMG 300 Gas pressure regulator
The RMG 200 consists of a main pressure regulator system (the actuator and main valve) and the pilot unit (two form of control stages and auxiliary pressure stage). RMG 200 is designed to ensure that gaseous media outlet pressure is kept constant and unaffected with outer influences; providing excellent control for inlet pressures and flux variations. Additionally, a delicate filter is pre-switched to shield the operator in heavy climate areas. The difference between the RMG 200 intake tension and the exit pressure is used for additional power. The adjustable auxiliary load stress can be used to influence the static amplification and adjust the regulator in line mode. The voltage to be controlled at the outlet is determined at the pilot site and advised to be controlled by the pilot line. The output pressure is compared to the reference value (point spring force). Pressure from RMG 200 Gas Pressure Regulator is applied to the diaphragm. The charging pressure in RMG 200 acts within the actuator and acts proportionally on the surface of the valve, thereby inducing a flow shift. The seat of the valve is fitted without compensating for the inlet pressure. The movement of the auxiliary force is adjusted as a load stress according to the variance in control and the loading pressure. RMG 200 pressure is therefore controlled in accordance with the setpoint value, taking into account the output voltage. The RMG 200 controller is designed in a way that makes maintenance easy. The control unit (actuator, valve plate and valve seat) can be removed by simply removing the four screws. A single-sealed valve with six different orifice sizes can be applied to the unit; keeping into account that the maximum permissible inlet pressure varies depending on the size of the hole.
