Dome pressure regulators

The pressure is regulated by the dome pressure regulator not by means of an adjustable pressure-actuated spring, but by means of a control gas that acts on a diaphragm in the dome. Depending on the pressure of the control gas that is set by means of a control pressure regulator, the diaphragm opens or closes the valve, thus changing the outlet pressure of the gas to be regulated. The process gas to be regulated can also be used as control gas and is then returned to the process circuit via a return valve. The pressure can also be regulated during operation without having to interrupt the process.


Dome Pressure Regulator – Series 747LE

Application

Dome pressure regulators are particularly suitable for line and machine installation for the process gas supply. The constant working pressure, irrespective of fluctuating tapping volumes and supply pressures, ensures a constant gas concentration and hence the quality of the downline processes. The use of dome pressure regulators is also to be recommended when large flow rates are supplied with small pressure differences.

Constant gas pressure for the process supply

The dome pressure regulator is operated in combination with a control pressure regulator (or proportional valve) via which the desired working pressure (downline pressure) is set. Either the gas to be regulated (process medium) or an external gas can be used as control gas for the control pressure regulator.

Dome Pressure Regulator – Series 757LE

Application

Dome pressure regulators are particularly suitable for line and machine installation for the process gas supply. The extremely constant working pressure ensured by the pilot control tube (PCT), irrespective of fluctuating tapping volumes and supply pressures, ensures a constant gas concentration and hence the quality of the downline processes.

The balanced seat design (BSD) compensates fluctuations in supply pressure. A bore through the valve seat and a special seal of the stroke movement relieves the pressure on the valve cone and the supply pressure exerts no force on the valve plunger.

The use of dome pressure regulators is also to be recommended when large flow rates are supplied with small pressure differences.

Process gas supply with particularly high back pressure consistency

757LE Series dome pressure regulators measure the prevailing working pressure not at the valve seat, but at the outlet from the pressure regulator, i.e. exactly at the point that is relevant for correct working pressure control (pilot control tube). The dome pressure regulator is operated in combination with a control pressure regulator (or proportional valve) via which the desired working pressure (downline pressure) is set. Either the gas to be regulated (process medium) or an external gas can be used as control gas for the control pressure regulator.
