Pressure Regulator 133 / 233 - Peppas Ltd

1 1 Pressure Regulator133 / 233 Benefits Accurate regulation Exchangeable componenttechnique Easy maintenance Suitable for HTBrequirements DVGW-approval (DIN 3380/81,VP 200).DescriptionThe 133/233 Regulator is adirect-acting, spring loadedregulator with an integratedsafety shut-off lever system ensures exactoutlet Pressure , and fastresponse when the flow are designed forresidential and industrial use,such as industries, and heatingplants, as well as for allinstallations where accuratepressure control, easyadjustment and fast responsetimes are required, such as forburners, industrial ovens,boilers, Regulator 133 / 233 Technical features Inlet Pressure rangePi: bar Outlet Pressure rangePo: 10 mbar 0,7 bar Accuracy classAC5/10, SG10/20, AG10/5 Operating temperature -20 C to +60 C Ambient Temperature -30 C to +60 C Acceptable gases Natural gas, propane, butane, air, nitrogen and all non-corrosive gases.

The requiredoutlet Pressure can be easily set toanother command range byadjusting the command variable, orby exchanging the spring.

3 Due totheir spring principle, theseregulators operate independently oftheir positions. They offer variousinstallation possibilities as a resultof flange connections between theactuator body and the regulatingunit and, flange connectionsbetween the actuator body and theSSV switching device. The nozzle,regulating unit, and SSV switchingdevice, can be exchanged withoutremoving the actuator body from theregulated member. The safety shut-off valve is equippedwith a thermally working models with a leaking gasblow-off valve (SRV) have a fixedblow-off pressure1). The blow-off Pressure is,independently of the setting of theoutlet Pressure , approximately30 mbar above ventilation/blow-off line has to beconnected to the ventilationconnection of the Regulator .

4 Themodels with safety diaphragms arenot equipped with the SBV and theventilation/blow-off line. If theworking diaphragm is damaged, thesafety diaphragm prevents gas fromleaking in unacceptable amounts. 1) See accuracy class SRV page 8diaphragm compartmentfeeler (1)(diaphragm)ventilationconnectiondesir ed-value settingloaded springloaded spring (10)flange connectionflange connectionactuator bodyactuator (4,7)(exchangeable nozzles)valve diskmeasuring unitwith lever system (34)valve rodreset with cap(26,35)SSV withthermal shutoffclosing spring (14)lever system (3)with actuatorregulating unit bodydesign withleaking-gas blow-off valve SRV(8)(6)(5)ventilation connectionwith sievedesign withintegrated safetydiaphragm3 Pressure Regulator133 / 233 Technical Data and Type DesignationType 133, Pi - bar Pressure rateInlet Pressure PN - bar PN - bar Outlet pressure8 - 420 mbar Flow rate, up to 65 m3/h Natural gas Working temperature-20 bis +60 C Connection / Sizesee page 5 Type 233, Pi - bar Pressure rateInlet Pressure PN - bar PN - bar Outlet pressure8 - 700 mbar Flow rate, up to 400 m3/h Natural gas Working temperature-20 bis +60 C Connection / Sizesee page 5 Type 133, Pi > - bar Pressure rateInlet Pressure PN - bar Max.
