pilot-operated pressure regulators RP 824
Only valves with open spring:
It is necessary to ensure on site, by an appropriate installation (e.g. not freely accessible) or
providing safety devices and/or positioning a clearly visible warning sign in accordance with
danger of
the regulations of EN 292 (formerly accident prevention regulations), that effective protection is
being
afforded against objects catching on an exposed spring in the pressure-regulating valve.
crushed
If required, MANKENBERG will assist in selecting a suitable type with closed bonnet.
Failure to observe this instruction: danger of crushing for the operating personnel
» Before installing a pressure-regulating valve, it is necessary to make sure that the pipeline section complies
with the recommended installation, as described in the relevant MANKENBERG data sheet. In particular, a
safety valve and a suitable strainer should be installed upstream of the fitting.
In some model series, a control line has to be laid between the pressure-regulating valve and
the pipeline by the customer – this is described in the above-mentioned recommended
installation.
note
Please note:
Only use control lines made of metal, not of plastic!
Distance of pressure-reducing valve/connection of control line to the pipeline 1 x DN upstream
of the valve and G10x DN downstream of the valve
Distance of back pressure regulator/connection of controllines to the pipeline ≥ 5x DN
upstream and downstream of the valve
Distance of vacuum control valve/connection to control line as for a pressure-reducing valve
DM or an back pressure regulator UV, according to design
When the medium is steam, lay the control line at an angle, with the gradient falling towards
the valve, see (catalogue) section <Know How Pressure-reducing valves%gt;
The control line should match the connection on the fitting.
Adjustable restrictors are integrated in the restrictor assembly to avoid vibrations.
The pressure-regulating valve should first be adjusted during the initial start-up by setting the adjusting screw
on the spring module to the operating conditions – see section
necessary to ensure before installation that there is sufficient room for the appropriate socket or open-jawed
spanner above/below the adjusting screw.
As a general rule, pressure-regulating valves should be installed in horizontal lines so that the
pilot valve points upwards.
