Intended Use
The RME 005 A Control Valve is used in conjunction with the
RVC 300 Controller or another control device for controlling gas
flows and thus maintaining a desired pressure in a vacuum
system.
It must not be used for controlling liquid gases.

Functional Principle
The RME 005 A Control Valve opens and closes as a function of
the control voltage.
It will close or remain closed in the event of a power loss.

3 Installation
3.1 Vacuum Connection
Caution
Caution: vacuum component
Dirt and damages impair the function of the
vacuum component.
When handling vacuum components, take appro-
priate measures to ensure cleanliness and prevent
damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare
hands increases the desorption rate.
Always wear clean, lint-free gloves and use clean
tools when working in this area.

3.1.1 Flange Connections
Remove the protective lids and mount two flange
connections (Accessories →25).

12 BP 5059 BEN (2011-10)
Remove the protective lids and install the product to the
vacuum system.
DANGER
DANGER: overpressure in the vacuum sys-
tem >1 bar
Injury caused by released parts and harm
caused by escaping process gases can result
if clamps are opened while the vacuum sys-
tem is pressurized.
Do not open any clamps while the vacuum
system is pressurized. Use the type of clamps
which are suited to overpressure.
DANGER
DANGER: overpressure in the vacuum sys-
tem >2.5 bar
KF flange connections with elastomer seals
(e.g. O-rings) cannot withstand such
pressures. Process media can thus leak and
possibly damage your health.
Use O-rings provided with an outer centering
ring.
