high pressure regulators R100 series - Euromekanik AB

1 high pressure regulators R100 theefficient, sunstainable and safe distribution ofgassesgeneralR100 The R100 series consists of several effective high pressure regu-lators (monitors) for use in gas transmission systems, gas distri-bution networks and industrial gas pressure regulating R064, the predecessor of the R100, has demonstrated itsquality and usability for over 25 years. With regard to the R064,the R100 has been improved considerably and modified accor-ding to current R100 is a pilot controlled regulator with direct acting featu-res. The direct acting part is extremely fast, while the somewhatslower pilot minimises set point R100 series consists of five types of regulators :- R100: the pilot-controlled standard model;- R100SO: same as R100 but spring to open;- R100S: same as R100/R100SO but with R100(S)-SO low-noise cage; - R100(S)-M : monitor version of the R100 with or without low-noise cage;- R101S: same as R100 with hybrid low-noise cage.

2 All standard models are supplied with a pilot and are suitable foran inlet pressure up to 100 bar and an outlet pressure range up to and including 60 R100S pressure regulator is a low-noise version of theR100, with noise reduction up to 40 dB(A). The special low-noisecage reduces the sound at the source instead of damping it andis therefore very effective and satisfies the current requirementson sound level. Except for the low-noise cage, the R100S isidentical to the standard version R100. Higher outlet pressuresare available on (S)-MThe R100(S)-M can be used as working or as a fully openmonitor.

3 A monitor is an emergency regulator that is activatedimmediately after the main regulator fails open. In contrast toother safety devices, such as safety shut-off or safety cut-offdevices, the gas supply is not interrupted if the main regulatorfails to open. The construction and operation of the R100(S)-Mare similar to those of to the standard R100 regulator. Thisgives the R100(S)-M its unique properties with respect to fastaction, low lock-up pressure , accuracy and stabillity, making itsuperior to other fully open and working monitor designs. Themonitor can be supplied with (R100S-M) or without low-noisecage (R100-M) and acceleration R101S is a regulator with a hybrid low-noise cage.

4 Usinga low-noise cage always results in a reduction of are circumstances when the regulator must maintain aspecific nominal capacity in combination with a low-noise levelin case of both high and low inlet pressures. In those instan-ces, a regulator with a greater nominal diameter normally hasto be an alternative to this, Gorter Controls has succesfully deve-loped the hybrid low-noise cage. This hybrid low-noise cageguarantees noise reduction under normal operating extreme situations where inlet pressure and gas speeds arelow as is noisegeneration, thenoise reductionpotential can beoptimised in combination withmaximum capacityand minimumnominal this way, over-dimensioning Netherlands Belgium Danmark Norway Sweden England France Germany - AustriaR100, R100S, R100SO R100(S)

Noise reduction up to 40 dB(A) is possible, depen-ding on the user's environment.

6 >> Optimal control at pressure differences from barThe BAAI R100(S) distinghuises itself from the competition byits ability to control the gas pressure perfectly at pressure dif-ferences from bar. The optimally balanced valve construc-tion of the BAAI R100(S) thus makes it highly suitable forextreme applications.>> Special patented valve seat- long maintenance interval due to the erosion-free enclosure of the seat ring- bubble-tight even at low temperatures- low lock-up pressure >> Excellent control characteristics- high degree of control accuracy ( 1%)- low lock-up pressure ( 2,5%)- fast responsebecause of.

8 Moreover, noise reduction increases as thedifference in pressure across the regulator / R100S / R101 SIn a balanced situation, the control member (10) allows a flow rateequal to the gas demand; the outlet pressure Pa is equal to the setpressure. When the outlet pressure is lowered, for example by an inc-rease in gas demand, the direct control loop of the regulator begins tofunction. The lower outlet pressure under the diaphragm (8) leadsdirectly to a diaphragm shift and the control member (10) also opensfurther, which quickly allows a greater flow rate to pass the controlmember (10), and the outlet pressure Pa is consequently diaphragm shift causes gas volume to increase in the actuator (7)and the spring (9) is further compressed.

9 Thus a new balance situati-on is created at a lower outlet pressure . The indirect control loop of thepilot corrects this decrease in pressure . Due to the pressure drop men-tioned, the diaphragm (3) of the pilot will attain a lower position, bywhich the pilot valve (4) will be opened further, which causes a gasflow to the actuator (7). This causes the pressure in the actuator to inc-rease almost to the point that the set outlet pressure is reached. Theoutlet pressure is set using the adjusting screw (1) and set point adjus-ting spring (2). The gas flow to the pilot valve (4) is provided by the sta-biliser part.

10 The stabiliser (6) is a small regulator that maintains a fixeddifference between the outlet pressure and the feeding pressure (5)despite variations in inlet pressure increase in outlet pressure causes the opposite to occur. If gasdemand ceases, the control member shuts completely and the actua-tor pressure is reduced to with the outlet pressure , enabling the powerof the spring (9) to shut the control member (10).operation R100 / R100S / R101S / R100(S)-Mthe specialist in the efficient, sustainable and safe distribution of gassesChina - Japan Australia - New Zealand Colombia Brasil - IranR100(S)-MThe operation of the R100(S)-M, used as working or as a full open moni-tor is similar to the standard regulator R100(S).
