In case of valve storage at temperature below -20°C do not use the valve until its
temperature reaches at least -20°C.
For the valves designed to be used with mixture of gases O
temperature is +5°C. In common use of the valve, frosting can appear on the valve
surface, which is caused by common physical reaction inside the valve when high
pressure in the valve is reduced to low pressure (Joule-Thomson effect). Check that
all associated equipment is connected to the valve via a hose of the length of at least
2 metres.

PRODUCT DESCRIPTION
Combination valve combines the function of shut-off valve of a high-gas cylinder and pressure
regulator for the use with medical gases. Gas from the cylinder is first controlled by the main
shut-off valve and then passes through the pressure regulator and finally delivered to the
patient through the flow outlet or the pressure outlet. Outlet positive pressure is fixed by the
manufacturer and each valve is provided with (external or internal) low-pressure relief valve
against undesirable exceeding of outlet positive pressure.
There are three basic alternatives:
•
Valve outlet via quick-coupler, the outlet flow is a constant one.
•
Valve outlet via calibrated nozzles, outlet flows can be changed by the control knob
•
The combination of both alternatives selector control knob.
A – Inlet stem
The valve is fitted to gas cylinder by a threaded
inlet stem. The inlet stem can be taper
threaded or parallel threaded of different size
depending upon cylinder size and material.
B – Filling port
Filling port is provided for filling the gas
cylinder. It includes a non-return valve (NRV).
The NRV means that special filling adaptors
are required to vent gas from the cylinder
during the filling process.
C – Pressure gauge
A cylinder contents pressure gauge is
provided. This can be active or non-active.
Versions fitted with active pressure gauge
enable to check cylinder content at shut-off
valve in both ON and OFF positions. The
versions fitted with non-active pressure gauge
enable to check cylinder content at shut-off
valve in ON position only.
D – Shut-Off valve
The combination valve is provided with a shut-
