Application, Characteristics, Technical Data Application Gas pressure regulator (GDR), direct-acting (operating without auxiliary power), for systems acc. to DVGW work sheets G 491 (A) and G 600 (A) (TRGI) Particularly suitable for dynamic regulation sections (e.g. gas fireplaces, natural gas supply systems, burner circuits, gas motor operation) Can be used as an equipment component on gas consumption facilities as defined in Regulation (EU) 2016/426. Can be used for the gases defined in DVGW work sheet G 260 / G 262 and neutral non-aggressive gases. (other gases on request) Integral...

Application, Characteristics, Technical Data Design and function R 100 The spring-loaded gas pressure regulator R100 has the function of keeping the outlet pressure of a gaseous medium constant within allowable limit values, independently of the effect of interferences, such as changes in the inlet pressure and/or in the gas tap, in the connected regulation section on the outlet side. The gas pressure regulator is composed of the actuator housing and the "diaphragm assembly plus actuator" functional unit. The double-seat valve seat model is pre-pressure-compensated. The gas flows through...

Types of Models / Options Safety diaphragm In the model with safety diaphragm, the safety diaphragm is located above the main diaphragm. When the main diaphragm is damaged, the safety diaphragm makes contact with the top cover of the diaphragm assembly and limits any inadmissible escape of gas into the surrounding atmosphere to a maximum of 30l/h (air). Safety diaphragm (Option not available for hydrogen version H2) Throttle valve RSD2 RSD2 throttle valve The RSD2 is a throttle valve which regulates the volume flow in the sensing/impulse line by means of a continuously adjustable...

Design Note All calculated pressures are absolute pressures for natural gas. (p+1 bar) The required KG value for a gas pressure regulator is determined with the smallest inlet pressure or lowest pressure drop. Calculation of the required KG value pd / pu > 0.5 Value flow rate coefficient KG at a subcritical pressure ratio KG = Qn / pd⋅(pu-pd) pd / pu ≤ 0.5 Value flow rate coefficient KG at a supercritical pressure ratio KG = 2∙Qn / pu The device is selected on the basis of its KG value from the table of flow rate coefficients (page 8) Device selection Closing pressure zone group: SZ 2.5 For...
