PRODUCT INFORMATION

Application, characteristics, technical data • device for systems acc. to DVGW worksheet G 600 (TRGI) or for RMG 300 „t" G 600 (TRGI) and G495/II • suitable for systems requiring dynamic regulation (gas furnaces) • suitable for natural gas and all non-aggressive gas media 2_ • large inlet pressure range • optional internal or external measuring connection _ • actuator with pressure compensation • easy maintenance due to exchangeable functional units _ • control system with optional - integrated safety relief valve (SBV) for gas leakages - with vent valve RMG 915 (if SBV is blocked) - with...

Application, characteristics, technical data *) Note: Where control devices are being used simultaneously for lower and upper actuating pressures, the difference between the two setpoint values pso and psu must be at least 10% greater than the sum of the re-engagement differentials Ap0 and Apu. **) The higher AG group applies to the first half, the lower AG group to the second half of the setpoint range.

The main valve body contains measuring bore holes which enable connecting an internal measuring connec- tion for the pilot and SAV. When using external measuring lines the internal connections are sealed using balls pressed into the bore holes. An adjustable throttle at the main valve body is used to tune the pilot to the pressure system. Optionally the safety relief valve for gas leakages (SBV) can be fitted to the regulating device. It is not required where a safety diaphragm has been fitted or is blocked when the venting valve RMG 915 is being added. The output pressure to be regulated...

Should the ambient temperature exceed the re- sponse temperature of the memory metal, the spring will extend longitudinally. Via the push rod the resul- ting high pressure forces the ball switch out of the snap-on pins. The conical closing body is set free and pressed by the pressure of the closing spring into the closing position between the valve seat and the abutment centred upon it. This design guaran- tees a safe closure. The closing body uses a material with a heat extension coefficient greater than that of the casing material. This produces increasingly greater closing forces with...

Device designation The diagram below applies to gas pressure regulators RMG 300 and RMG 300 „t" with integral SAV unit. It indicates the nominal flow for natural gas as a function of inlet pressure pe and outlet pressure pa. Nominal flow diagram for gas pressure regulator RMG 300 „t" _ i external measuring connection Nominal flow pn In m3/h (applicable to natural gas) The maximum nominal flow values qn can normally only be achieved where the outlet pipe is widened to a larger size. A maximum nominal flow of approx. 20 m/s also applies for this measuring point.
