5. PRODUCT DESCRIPTION

Combination valve combines the function of shut-off valve of a high pressure gas cylinder and
pressure regulator for the use with medical gases. Gas from the cylinder is fi rst controlled by
the main shut-off valve and then passed through the pressure regulator and fi nally delivered to
the patient through the fl ow outlet or the pressure outlet. Outlet positive pressure is fi xed by the
manufacturer and each combination valve is provided with a low-pressure relief valve to protect
against undesirable exceeding of outlet pressure.
There are two basic alternatives:
• Valve outlet via calibrated nozzles, outlet fl ows can be changed by the control knob
• Valve outlet via quick-coupler (the outlet fl ow is a constant one) in combination with valve
outlet via calibrated nozzles where outlet fl ows can be changed by the control knob
A INLET STEM
The combination valve is fi tted to gas cylinder by a threaded inlet stem. The inlet stem can
be taper threaded or parallel threaded with diff erent size depending on the cylinder size and
material.
B FILLING PORT
A fi lling port is provided for fi lling the gas cylinder at a fi lling station, it has no function for
patient use. It includes a non-return valve (NRV). The NRV means that special fi lling adaptors
are required to vent gas from the cylinder during the fi lling process (venting and/or vacuuming
of cylinders).
