Fine dosing metering valve with good control characteristics at high and low flow levels. (at maximum 10
knob turns open to closed). Please keep attention: only shut-off valves guarantee the secure interruption of
gas flow.

INSTALLATION
6.1. CYLINDER PRESSURE REGULATORS
The threads of the cylinder valve and the union nut must
be in impeccable condition.
Always use new gaskets. Gaskets must not be deformed
and must show no traces of dirt or metal turnings.
Attention: Do not use spanner extensions because they
may destroy the thread and the gasket. This can lead to
leaks or to complete and uncontrolled loss of the gas
supply.
When connecting or changing cylinders containing toxic
or corrosive gases, appropriate personal protection
measures must be taken (respiratory protection, eye
protection and protective clothing). Observe the MAK
values (maximum workplace concentration value; see
Technical norms for dangerous substances, TGRS 900)
and have the correct respiratory protection filters at
hand..
Before connection, check the rating plate to determine whether the equipment is suitable for the intended
use (type of gas, pressure, etc. see section 5).
PREPARATION
Use only cylinder connections appropriate for the type of gases used according to DIN 477.
CONNECTION TO THE CYLINDER
First screw the union nut onto the cylinder by hand. Pay attention to right- and left-handed threads! Align
1.
the regulator. Do not tilt it when setting it on!
Tighten the union joint with the appropriate open-end spanner. Do not use spanner extensions!
