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 first controlled by
the main shut-off valve and then passed through the pressure regulator and finally delivered
to the patient through the flow outlet or the pressure outlet. Outlet pressure is fixed by the
EN
manufacturer and each combination valve is provided with a low-pressure relief valve to
protect against pressure regulator failure.
There are three basic alternatives:
•
combination valve with quick-coupler outlet, the outlet pressure is constant, and flow is not
controlled by the combination valve
•
combination valve with outlet via calibrated nozzles, outlet flows is controlled by the
combination valve and can be changed by the control head,
•
the combination valve of both alternatives.
