INTrODuCTION

Scope of manual
This manual provides instructions for installation, startup,
maintenance and spare parts ordering for the RP series
spring loaded regulators.
Product Description
The RP Series regulators are direct-operated with
non-balanced trim.
They are usually supplied with built in filter and can be also
provided with slam-shut controller for minimum pressure,
maximum pressure or minimum and maximum downstream
pressure.
The regulators of the RP series due to their operating
specifications are mainly used in those system where
sudden capacity variations are required, or else, where the
cut-off of the gas distribution is controlled by solenoid valve,
such as for the feeding of burners.

This product has been designed to be used with fuel gases of
7
1st and 2nd family according to EN 437, and with other non

aggressive and non fuel gases. For any other gases, other
than natural gas, please contact your local sales agent.

The following versions are available:
RP/011 • RP/022 • RP/033: Regulator
RP/011/66 • RP/022/66 • RP/033/66: Regulator with slam-shut
The standard gas pressure devices (regulators and safety
shut-off devices) are those used in the assemblies dealt with
into EN 12186 and EN 12279 and their use has to be under
the provisions into ENs 12186 & 12279.
Fail open stand-alone regulators cannot be used as a safety
accessory according PED 97/23/EC to protect downstream
pressure equipment.
In the pressure regulators (with or without built-in safety
shut-off devices) manufactured by Emerson Process
Management shall be used additional pressure accessories
(e.g. pilots or filters) manufactured and labeled by Emerson
Process Management.
Emerson Process Management will be not responsible for any
possible inefficiency due to installation of not own production
additional pressure accessories (e.g. pilots or filters).
When pressure containing parts of possible built-in safety
shut-off device (SSD) valve and pilot have different
maximum allowable pressures, the SSD is differential
strength type.

    Type RP OPEraTION Figure 5. RP Series Operational Schematic The movements of the diaphragm (D) are transmitted to the valve disc (O) by the stem (S) and the levers system (L). The downstream pressure through the pulse pipe (I) exerts a force under diaphragm (D) and this force is counteracted by the adjusting springs (M). The gas pressure on the diaphragm tends to close the valve disc;...
